Herbs and the Nervous sytem Flashcards
What are the 3 devisions of the nervous system
cns, pns, ens
What is the ENS?
The ENS is composed of nerve cells in the wall of the gastrointestinal tract that are able to sense information and carry out a response without input from the CNS. ENS neurons can also independently send signals to the CNS, thus communication between the CNS and the ENS is bidirectional.
What is the PNS?
The PNS connects the CNS to the body’s organs, muscles, blood vessels, and glands.
What is the CNS?
The CNS includes the brain and spinal cord.
What connects the two hemispheres of the brain?
corpus callosum
name the 4 lobes that the cerebral cortex is devided into?
Frontal, Temporal, Perietal, Occipital
What is the function of the frontal cortex?
The frontal lobe (located at the front of the brain) is responsible for certain aspects of motor activity, speech, and thought processing.
what is the function of the perietal lobe?
The parietal lobe (located above the temporal lobe) processes information about touch, taste, pain, and temperature.
what is the function of the Temporal lobe?
To process auditory information
What is the funciton of the Occipital lobe?
The occipital lobe (located at the back of the head) receives and processes visual information.
What is the function of the basal ganglia?
The basal ganglia regulates skeletal movement and other motor functions with information it receives from the cerebral cortex.
what is the function of the thalamus?
The thalamus receives information from sensory systems of the body (e.g., the retina) and sends it to the cerebral cortex.
What is the function of the hypothalamus?
The hypothalamus regulates certain metabolic processes, including body temperature and the feeling of hunger or thirst. The hypothalamus also synthesizes and secretes hormones and acts as a bridge between the nervous and endocrine systems of the body
What structures are part of the limbic system and what is it’s function?
The limbic system, sometimes called “the emotional brain,” is a collection of tiny structures, including the amygdala and the hippocampus. Limbic tissues are found on both sides of the thalamus, just beneath the cerebrum. These structures play a key role in our emotional responses, the formation of memories, and our ability to make decisions, learn, and motivate.
What is the function of the medulla oblongata?
the brainstem is composed of the midbrain, the pons, the medulla oblongata (also known as the medulla). Nerve cells within the brainstem are involved in many processes including arousal and sleep, muscle tone and muscle reflexes, orchestration of breathing, blood pressure regulation, and modulation of pain. The medulla connects the brain to the spinal cord and allows for communication between the brain and the rest of the body.
what is the function of the cerebellum?
the cerebellum coordinates the execution of movement. It doesn’t initiate movement, but it receives sensory input from the spinal cord and other parts of the brain and processes these in order to create coordinated and precise movement—contributing to fine motor activity.
what is the function of the cerebral cortex?
The part of the cerebrum that provides the abillity to think, reason, and understand language. Devided into two hemispheres, each devided into 4 lobes.
what is the function of the cerebrum?
Controls many of the bodies functions, including: muscle function, voluntary activity, emotions, senosry integration, and learning
What is the function of the corpus collosum?
ensures communication between the left and right hemisphere in the brain.
what is the function of the pons?
relays information from the cerebrum to the cerebellum, along with the medulla it coordinates the involuntary control of the breath, maintains equilibrium by co-ordinating muscular movement.
what is the function of the midbrain?
controlls the movement of the eyes and also processes auditory and visual signals.
what are the three types of nuerons found in the brain?
sensory neurons, motor neurons, and interneurons.
what is the function of sensory neurons in the brain?
Sensory neurons typically have one or more long dendrites and a short axon and carry messages from sensory receptors throughout the body into the central nervous system.
What is the function of motor neurons?
Motor neurons have a long axon and short dendrites and relay messages from the central nervous system to muscles and glands.
What is the function of interneurons?
Interneurons are found only in the central nervous system where they connect one neuron to another.
What is the most common cells in the nervous system?
neurons are not the most common type of cell in the nervous system. Another type of cell, glial cells (also called neuroglia), outnumber neurons by 10-50:1
what is the function of glial cells?
Glial cells provide structural stability to neurons by wrapping themselves around them. They have a variety of other functions, including transferring nutrients from the blood to the neurons and creating myelin to support and insulate axons.
How do neurons communicate with one another?
Communication between neurons occurs in the synapse between the axon of one neuron and the dendrite of another. One cell can have over 150,000 synapses so there can be a lot of communication going on in one tiny area (Silverthorn, 2004)! There are two types of synapses: the electrical synapse and the chemical synapse. Chemical synapses are much more common and use chemicals called neurotransmitters to carry information from one neuron to another. There are many neurotransmitters that our body uses to communicate including norepinephrine, dopamine, and serotonin. Electrical synapses are less common and are only used when extremely rapid conduction of a signal is necessary (Costanzo, 2010).
What is the function of the spinal cord?
the spinal cord, which connects the brain to the rest of the body.
explain the blood-brain barrier
The capillaries of the CNS have a slightly different structure than the capillaries in the rest of the body. Weaving all throughout the brain, these capillaries are highly selective—they only allow certain substances to pass through their membranes. This web of selective capillaries is known as the blood-brain barrier and it is vital in isolating the brain from harmful substances that may be in the blood and sheltering the brain from toxins and from fluctuations in hormones, ions, and neurotransmitters.
Which two substances readibly cross the blood brain barrier?
Two important substances that do cross the blood-brain barrier are oxygen and glucose. Neurons consume oxygen at very high rates and the brain is responsible for about half of the body’s glucose use (McCance et al., 2010)! Certain pharmaceutical medications and some herbal constituents are also able to cross the blood-brain barrier.
What is the function of the Reticular Activating System in the brain?
Basically, the RAS connects the seat of involuntary functions in the brain (the brainstem) to the seat of consciousness in the brain (the cerebral cortex). Besides processing arousal and sleep, the RAS filters the information that we receive from our external environment, giving us the ability to focus on one thing and be only mildly aware of other things around us. It also aids in coordination during any physical activity, including the seemingly simple act of walking.
What is the circadian rhythm?
While the RAS keeps our brain quiet while we sleep, our circadian rhythm is what actually initiates that sleepy feeling. Circadian rhythms are physical and mental changes that follow a 24-hour cycle and that are typically in response to the amount of light or darkness in our environment. All of this is controlled by our internal “clock,” which resides in a complex network of neurons in the hypothalamus of the brain.
Circadian rhythms influence our sleep-wake cycle (because of the influence on melatonin secretion), the release of hormones, our body temperature, and insulin and cortisol release. Because they have such a wide-ranging influence on various body systems and functions, disruption to circadian rhythms can have significant effects on our health and wellness
How do emotions affect the body?
For a human to feel an emotion, sensory stimuli must first be fed into the cerebral cortex, where a perception of that stimuli is created. Information about the stimuli is then passed on to the limbic system. Feedback from the limbic system back to the cerebral cortex creates awareness of the emotion and feedback to the hypothalamus and brainstem initiate voluntary, as well as involuntary responses, such as changes in heart rate, behavioral changes, and movement of the body (Silverthorn, 2004). Thus, an emotion is much more than a thought in the brain; it can affect all areas of the body.
What are the two divisions of the PNS, as well as their functions?
The PNS has two divisions: the somatic motor system and the autonomic system. The somatic motor system contains neurons that control skeletal muscles (this is also known as the voluntary division of the PNS, because even though we don’t normally think, “I am going to pick up my right leg now,” as we are walking, we can control these movements). The autonomic system, or the involuntary division, controls actions of smooth muscles, cardiac muscles, and many glands.
What are the two divisions of the autonomic nervous system?
The autonomic nervous system is further divided into sympathetic and parasympathetic branches. These two branches work in tandem, each taking the lead depending on the situation.
when is the parasympathetic nervous system active?
The parasympathetic nervous system is activated when a person is resting and is often called the rest-and-digest mode of the nervous system.
Pupils: constrict
Saliva production: increases
heart rate: reduces
Bronchia: constricts
Digestive organs activity and bloodflow: increase
Pancreas activity: increase
Gallbladder activity: increase
urinary bladder: constricts
genitals: stimulates errection
when is the sympathetic nervous system active?
The sympathetic branch is dominant in stressful situations. When the sympathetic nervous system is dominant, one is in what is commonly referred to as fight-or-flight mode.
Pupils: dilate
Saliva production: decrease
Heart rate: increase
Bronchia: dilate
Digestive organs activity and bloodflow: decrease
Pancreas activity: decrease
Gallbladder activity: decrease
Adrenal madula: releases adrenalin/nordrenalin
urinary bladder: relaxes
genitals: stimulates orgasm.
What does the ENS do?
the ENS is composed of millions of neurons in the wall of the gastrointestinal tract (Silverthorn, 2004). These neurons receive messages from the vagus nerve and are responsible for promoting secretion of digestive juices, permitting food to pass from one area of the digestive system to another, and controlling peristalsis.
How do emotions affect digestion?
The ENS, the nervous system located in the gastrointestinal tract, controls digestion with or without input from the CNS and influences our mood and emotions.
Because emotional stimuli can share the same nervous system pathways as messages about digestion, emotions can also directly affect digestion. We feel the effects of the ENS when we experience nervousness as “butterflies in the stomach” or have diarrhea from anxiety. In fact, the ENS plays a key role in determining our mood and emotions. Thus, keeping the digestive system healthy is a great way to help avoid nervous system imbalance.
Which catogory of herbs offers support during stress?
adaptogens
what is stress?
stress is any response to a perception that requires an adjustment/change in the body, and is necessary for staying alive. Our body is constantly experiencing stress as our interior and exterior environments fluctuate and the body works to maintain homeostasis
what is homeostasis?
homeostasis, a state of physiological balance that allows our cells to remain stable despite external fluctuations and changes. It is when the body is unable to maintain that homeostasis that we start to notice the effects of stress on our physical body, especially the nervous system, and thus in our behavior, thoughts, and emotions.
What happens in the body during the stress response?
When the nervous system interprets a situation as stressful, the sympathetic nervous system (SNS) is activated. When the SNS is activated, the neurotransmitters norepinephrine (also known as noradrenaline) and epinephrine (also known as adrenaline) are released by the adrenal medulla (tissue located in the core of the adrenal glands, the little glands that sit on top of each kidney). These hormones are what cause the fight-or-flight response
The release of norepinephrine and epinephrine causes several shifts in the body: the heartbeat quickens, the breath quickens, blood pressure increases, glycogen (a form of stored energy) is pulled from storage and converted to glucose for energy, and the bronchioles of the lungs dilate. This all happens very quickly—minutes after we perceive a stressful situation
Another section of the adrenal gland—the cortex, or the outer tissue of the adrenal gland—secretes different hormones in response to stress, including cortisol. Receptors for cortisol are in virtually every tissue of the body so stress is truly felt everywhere (Tsigos et al., 2016). Cortisol is responsible for many physiological changes that would be useful if we needed to fight or to run for our lives, but are not as useful when we are driving in traffic “stressing” about our to-do list. Cortisol frees up bits of protein from our muscles and other tissues to liberate amino acids so that the liver can continue to produce glucose and keep blood sugar elevated. This way, the brain and heart receive more sugar than the rest of the body, allowing for continued physical activity and focus
In the first hour or so after cortisol is released, the immune system is stimulated (this is so that the body is prepared to resist trauma, infection, and hemorrhage). However, after that period of time, there is a decrease in immune activity and the body begins to not respond as well to immune challenges and makes fewer important immune cells such as macrophages and T-cells
What are the six effects of coritisol in the body?
- Cortisol breaks down muscle protein to liberate amino acids.
- Cortisol boosts prolactin levels, which antagonizes dopamine (our pleasure hormone).
- Cortisol stimulates the immune system in the first hour
or so after it is released, and later suppresses it - Cortisol decreases delta wave sleep patterns.
- Cortisol reduces absorption of dietary calcium
- Cortisol inhibits gonadotropinreleasing hormone,
which results in a decrease in the secretion of sex
hormones
How does stress effect sex hormones in the body?
Sex hormones, such as progesterone, estrogen, and testosterone, also decrease in response to cortisol (why would our body want to reproduce when we are assumed to be in a life-or-death situation?). The decrease in secretion of sex hormones is due to the inhibition of gonadotropin-releasing hormone (GnRH) by cortisol. GnRH is a sex hormone secreted by the hypothalamus and when it is inhibited by cortisol, it is not able to do its job of triggering the pituitary gland to produce and secrete other sex hormones (Breen et al., 2008).
How does stress cause osteoporosis?
When cortisol levels are high in the body, there is also a reduction in absorption of dietary calcium (potentially resulting in osteoporosis over the long term) and an increase in prolactin levels.
How does stress cause depression?
Prolactin antagonizes dopamine, our pleasure hormone—we don’t feel as much pleasure while we are perceiving stress. For this reason, among others, chronic stress has been associated with depression (van Praag, 2005).
Why does stress effect our abillity to sleep deeply?
Deep sleep is also less likely to happen during times of stress because there is a decrease in delta wave sleep patterns with increased cortisol (Bush & Hudson, 2010) (we need to run or fight, not take a nap!). Because we are meant to be fighting or fleeing when we are in this state,
What is the best way to clear cortisol from the body?
exercise clears cortisol from the body. If our body is not active (e.g., if we are watching a stressful movie while we sit leisurely on the couch) cortisol is cleared less quickly (Tsigos et al., 2016).
How does chronic stress create a mental state that makes it difficult to maintain homeostatis?
When stress becomes chronic (when the body is chronically exposed to stress hormones), our perception of “reality” can shift, causing us to be hyper-vigilant and thus perceive more stress, creating a cycle that feeds itself. Due to this feedback loop, chronic stress can cause anxiety, depression, weight loss or gain, fatigue, sleep disruption, insulin resistance, and hypertension. From chronic stress we may enter a state in which we are less able to maintain homeostasis in the body when the environment around us shifts
What are the 3 hallmarks of adaptogens?
- Improve resistance to and recovery from stressors;
- are generally safe for most people;
- have non-specific activity (instead of affecting one area of the body, they have a general effect on increasing resistance to stressors on the body as a whole).
How do adaptogens combat stress?
Adaptogens work to maintain our reserves of energy, enhancing the process of recovery from chronic stress (and usually other conditions, as well), and many can “recharge” the body, bringing it back from depletion. Most adaptogens are also immunomodulating (they tonify and restore balance in the immune system) and antioxidant (they help to neutralize potentially damaging agents, such as free radicals, from the body and so are often considered beneficial in warding off cancer).
Which herbs are known adaptogens?
Asian Ginseng (Pinax ginseng)
Ashwagandha – Withania somnifera (Solanaceae) – Root
Codonopsis – Codonopsis pilosula (Campanulaceae) – Root
Eleuthero – Eleutherococcus senticosus (Araliaceae) – Root
Tulsi – Ocimum tenuiflorum (Lamiaceae) – Aerial parts
What is the difference between white and red ginseng?
Red ginseng is white ginseng that has been steamed.
Red ginseng is more warming and stimulating than white ginseng
Red ginseng is more readibly available.
What are the herbal actions of Asian Ginseng?
Adaptogen, antioxidant, hypoglycemic, hypolipidemic, immunomodulant, stimulant
What kind of stress is Asian Ginseng best suited for?
Asian ginseng is an adaptogen specific for stress in the cardiovascular system and for individuals whose stress is affecting their heart or blood vessels.
What are the safety issues related to ginseng?
Asian ginseng may decrease blood clotting in people taking warfarin. Asian ginseng may interfere with blood glucose regulation and people with diabetes should only take Asian ginseng under the guidance of a qualified healthcare practitioner (Gardner & McGuffin, 2013).
What are the herbal actions of Ashwaganda?
Adaptogen, anti-inflammatory, antioxidant, antispasmodic, hepatoprotective, hypolipidemic, immunomodulant, nervine, sedative, thyroid stimulant
Is the energy of ashwaganda cooling or warming?
warming.
what does the name Ashwaganda mean?
ashwagandha means “that which has the smell of a horse, as it gives the vitality and sexual energy of a horse”
What kind of stress is Ashwaganda best suited for?
provides a boost in libido! It is best used as a long-term sexual tonic (ashwagandha does not often work acutely, to “get in the mood,” rather, it tends to work over the long-term for the person who’s libido suffers due to chronic stress) (Lad & Frawley, 1986).
a good choice for those with exhaustion, anxiety, insomnia related to stress, cloudy thinking, and lack of energy
Is Ashwaganda stimulating or calming?
whereas many adaptogens are stimulating, ashwagandha is calming. In fact, the species name (somnifera) suggests its use as a sedative and indeed, for some, it can be useful as a sleep aid. However, for some individuals, especially those with a lot of nervous energy, ashwagandha can, and should, be taken in the morning—the sedating qualities of the plant will calm the nerves rather than send them back to bed.
What are the known safety issues with Ashwaganda?
Ashwagandha should not be used in pregnancy unless under the care of a qualified healthcare professional. Because ashwagandha can modify blood glucose levels, those with diabetes should be under the care of a qualified healthcare professional when taking ashwagandha (Gardner & McGuffin, 2013).
Which adaptogen is often called “poor man’s ginseng” and is used as an analog for ginseng in chinese medicine?
Codonopsis
What are the herbal actions of Codonopsis?
Adaptogen, expectorant, hypoglycemic, immunomodulant
Is the energetics of Codonopsis warming or cooling?
slightly warming and moistening
What kind of stress is Codonopsis best suited for?
Codonopsis has a strong affinity for the digestive organs and strengthens both digestion and assimilation. Modern Western herbalists use codonopsis as an adaptogen when stress leads to digestive upset such as a lack of appetite, diarrhea, and/or bloating
How is Codonopsis used in chinese medicine?
In Chinese medicine, codonopsis is known as dang shen, and is regarded as an analog to Asian ginseng, though not as strong in its actions. Chinese medicine practitioners use codonopsis for Spleen and Lung qi deficiencies, fatigue, diarrhea, chronic cough, and organ prolapse
What are the safety issues with Codonopsis?
No known safety issues
Can codonopsis be used to treat respiratory and heart disease, and anemia?
Yes
What are the herbal actions of Eleuthero
Adaptogen, antioxidant, hypolipidemic, hypotensive, immunomodulant
Is the energy of Eleuthero cooling or warming?
warming
What kind of stress is Eleuthero best suited for?
It’s primary function is to increase endurance. Best suited for those who are suffering from burnout and fatique but who needs to keep going.
eleuthero is an adaptogen specifically “for those that work hard, play hard, and hardly sleep” (2007, p. 160). Eleuthero is commonly used to enhance physical performance and reduce fatigue and for most people, it does this without being overly stimulating. Germany’s Commission E approved eleuthero as “a tonic for invigoration and fortification in times of fatigue and debility or declining capacity for work and concentration, also during convalescence” (American Botanical Council, 2007, para. 5). Eleuthero is specifically indicated for exhaustion, irritability, insomnia, and mild depression and conditions such as angina, hypertension, hypotension, and various types of neuroses resulting from the stress response (Hoffmann, 2003). Eleuthero is also normalizing to the thyroid, so can be beneficial for those with hyperthyroid as well as hypothyroid conditions (Wood, 2008).
What is the difference between Eleuthero and other stimulants?
“The use of [eleuthero] typically generates no side effects, unlike traditional stimulants that possess addiction, tolerance and abuse potential, produce a negative effect on sleep structure, and cause…‘come down’ effects. Furthermore, [eleuthero] effectively increases mental performance and physical working capacity in humans”
What are the herbal actions of Tulsi?
Adaptogen, alterative, anticancer, antidepressant, antimicrobial, antioxidant, antispasmodic, cardiotonic, carminative, diaphoretic, emmenagogue, expectorant, galactagogue, immunomodulant, nervine, radioprotective
What is the relationship between tulsi and the hindu goddess Tulasi?
In Hindu mythology, tulsi is an incarnation of the goddess Tulasi—a goddess of protection. Tulsi plants are often planted at the door of one’s dwelling to protect all who live there. Use tulsi as your own protector against stress, illness, anxiety, and sadness!
What kind of stress is Tulsi best suited for?
Tulis is best suited for stress that causes anxiety and which impairs cognition and memory.
Tulsi is a nervine and anxiolytic, and has been shown to attenuate generalized anxiety and correlated stress and depression (Bhattacharyya et al., 2008). It is both a relaxing and stimulating nervine, promoting calm focus. It can help with cognitive performance and in cases of poor memory, attention deficit disorder (ADD), and attention deficit hyperactivity disorder (ADHD) because of its ability to enhance cerebral circulation, an action that may improve overall function (Winston & Maimes, 2007).
How is tulsi used in Auyerveda?
In Ayurveda, tulsi is used to kindle the digestive fire, clear mucus from the lungs or head, and strengthen the immune system. It is indicated for cold, congested, stuck conditions, which may be helped by the gently stimulating and moving effects of the volatile oils. It is considered balancing to all doshas, though may aggravate pitta dosha in excess (McIntyre & Boudin, 2012).
What are the safety concerns with Tulsi?
Tulsi may interfere with blood glucose regulation and people with diabetes should only take tulsi under the guidance of a qualified healthcare practitioner (Gardner & McGuffin, 2013).
What are the energetics of Tulsi?
Warming and drying
How does tulsi combat stress related depression and anxiety?
Tulsi affects reduces the production of cortisol via the HPA axis and at the same time increases the production of dopamine and seratonin
What are nervine herbs?
Nervines are essentially plants that “calm the nerves” and most nervines contain volatile oils, which, in part, are responsible for their nervine effect.
What role do the volatile oils play in nervine herbs calming effect?
Most volatile oils are nervine, carminitive, antispasmodic and anti-inflamatory. In addition to releasing tension in the nervious system, they also sooth and relax the smooth muscle of the vascular and digestive system as well as that of other organs, relieving spasms and making us more feel relaxed and at ease.
Volatile oils also act on our sense of smell, which is directly connected to the limbic system of the brain, which governs emotion and memory. When we catch the scent of an aromatic plant, nerve endings are stimulated to send impulses to the limbic system and to structures that manage stress in our internal organs;
All and all, this balanced state in our internal organs are reflected in our emotions.
Which herbs are nervines?
Lemon balm – Melissa officinalis (Lamiaceae) – Aerial parts
Lavender – Lavandula spp. (Lamiaceae) – Flower bud
Catnip – Nepeta cataria (Lamiaceae) – Aerial parts
Skullcap – Scutellaria lateriflora (Lamiaceae) – Aerial parts
What are the herbal actions of Lemon balm?
Antidepressant, antioxidant, antispasmodic, antiviral, carminative, diaphoretic, nervine, radioprotective
What are the energetics of Lemon balm?
Cooling and drying
What are the specific indications of lemon balm?

Mild tranquilizer used to ease nervous tension.
What are the safety issues related to catnip?
Catnip should be avoided in pregnancy
What is the botanical name for catnip?
Nepeta cataria (Lamiaceae)
Which parts of the catnip plant are used
aerial parts
What is the botanical name for skullcap?
Skullcap – Scutellaria lateriflora (Lamiaceae)
Which parts of the skullcap plant are used?
Aerial parts
What are the herbal actions of skullcap?
Analgesic, antispasmodic, bitter, hypotensive, nervine
What are the energetics of skullcap?
Cooling and drying
What are the specific indications of skullcap?
One of the best herbs for the mind that just won’t quiet down, a clinical trial of skullcap showed “noteworthy anxiolytic effects” in healthy subjects (Wolfson & Hoffmann, 2003). Skullcap is a great herb to turn to when there is a feeling of stuckness resulting from a constant state of stress that leaves one tense, exhausted, and suffering from heart palpitations (Rose, 2007). Skullcap is also indicated for people needing to release control, or as herbalist David Winston describes, those who are likely to “fly off the handle” when under stress and then feel hopeless and out of control as a result (Rose, 2007).
David Hoffmann (2003) calls skullcap “perhaps the most relevant nervine available to us in the Western materia medica. It effectively soothes nervous tension while renewing and revivifying the central nervous system” (p. 582). In a nod to its uplifting, nervine effects, herbalist Kiva Rose has renamed the plant with the much lovelier moniker “blisswort.” In general, skullcap is considered a nerve trophorestorative, meaning it restores balance to the nervous system by nourishing and rebuilding nerves. Holmes (2006) describes it as a nervous system restorative “for debilitating effects due to longstanding unproductive stress, whether caused by disease or excessive lifestyle” (p. 509).
Some individuals experience skullcap as a sedative, while others say that too much can make them feel jittery. Both effects are uncommon. Skullcap can be used fresh or dried for tea and tincture, though some herbalists recommend a fresh plant tincture as the most potent preparation of skullcap.
What are the safety issues related to skullcap?
Avoid during pregnancy
Avoid when taking sedatives (potentiates)
Skullcap products in the marketplace have a history of adulteration with germander, a hepatotoxic plant, so it is important to source skullcap from a reputable, trustworthy source. Overdose of adulterated skullcap tincture resulted in stupor, confusion, giddiness, and twitching of limbs. Holmes (2006) warns that skullcap root should be avoided during pregnancy. Skullcap may potentiate sedative medications (Hoffmann, 2003).
What is the botanical name for Linden?
Linden – Tilia spp. (Malvaceae)
What parts of linden are used?
Flower and bract
What are the herbal actions of Linden?
Anodyne, antifungal, antispasmodic, antitussive, carminative, diaphoretic, diuretic, expectorant, hepatoprotective, hypotensive, nervine
What are the energetics of linden?
Cooling and moistening
What are the specific indications for Linden?
Linden has been used widely for its calming and anxiolytic effects. Bathwater infused with linden has been used traditionally to ease anxiousness, irritability, and restlessness and to foster a calm and relaxed state for adults and children alike. Internally, an infusion of linden flowers is used in many cultures for people of all ages as a soothing nervine or gentle sedative for quelling anxiety, hyperactivity, and insomnia (King et al., 1898). As an infusion, linden has an agreeable aroma and flavor, owing to its aromatic volatile oils, and it combines well with other herbs in tea blends.
Linden has an affinity for the heart. It has a traditional reputation for cardiovascular and circulatory disorders, such as atherosclerosis, hypertension, and swollen ankles, and is sometimes combined with hawthorn for this purpose (Hoffmann, 1998; World Health Organization, 2010). Its relaxing effects and circulatory benefits can ease nervous headaches, sinus headaches, and migraines (Hoffmann, 1998; World Health Organization, 2010)
What safety issues are associated with Linden?
Linden should be taken separately from iron supplements and iron-rich food, as it may reduce iron absorption (Gardner & McGuffin, 2013).
What is the botanical name for chamomile?
Chamomile – Matricaria chamomilla (Asteraceae)
Which parts of chamomile are used?
Flower
What are the herbal actions of chamomile?
Anti-inflammatory, antimicrobial, antispasmodic, bitter, carminative, nervine
What are the energetics of chamomile?
Cooling and drying
What are the specific indications of chamomile?
Chamomile makes a soothing tea or tincture helpful for easing anxiety and tension. One clinical trial reported a significant anxiolytic effect in patients with mild to moderate generalized anxiety disorder who were given chamomile (Amsterdam et al., 2009). Another study a few years later by the same researchers found that chamomile “may provide clinically meaningful antidepressant activity” (Amsterdam et al., 2012). Chamomile may also help ease premenstrual syndrome (PMS) symptoms. A randomized, double-blind study reported a significant reduction in emotional symptoms after taking 100 mg of chamomile three times a day (Sharifi et al., 2014).
Due to its anti-inflammatory properties and cooling nature, chamomile is especially beneficial for those who experience anger and inflammation when under stress. A classic digestive herb due to its bitter, carminative, antispasmodic actions, chamomile also benefits those who experience gastrointestinal upset under stress.
What safety issues are associated with chamomile?
Those with allergic sensitivity to Asteraceae (daisy) family plants may experience sensitivity to chamomile. Chamomile has also been shown to potentially reduce iron absorption in humans when taken at the same time (Bone & Mills, 2013).
Which herbs are usefull for heart palpatiations caused by stress?
Some individuals feel the effects of stress in their heart as heart palpitations or a rapid heart rate. Linden (Tilia spp.) bract and flower, motherwort (Leonurus cardiaca) aerial parts, or hawthorn (Crataegus spp.) berry, leaf, and/or flower could be added to an anti-stress formula for this individual.
Which herbs are useful for digestive upsets caused by stress?
The digestive system of some individuals is affected by stress and manifests as “butterflies,” nausea, diarrhea, or indigestion. Chamomile (Matricaria chamomilla) flower, tulsi (Ocimum tenuiflorum) aerial parts, or lemon balm (Melissa officinalis) aerial parts could be added to an anti-stress formula for this individual.
Which herbs are useful for muscle tension caused by stress?
Some individuals hold stress in their muscles, resulting in tension in various places in the body. Skullcap (Scutellaria lateriflora) aerial parts or blue vervain (Verbena hastata) aerial parts could be added to an anti-stress formula for this individual.
What is the nervous system called in Ayerveda?
majja dhatu
Which dosha is the nervous system closely linked to?
vata dosha
Why is the nervous system closely linked to vata dosha?
The concept of movement applies to our thoughts and nerve impulses. Wherever movement exists, vata is present. In fact, the ancient ayurvedic rishis, or sages, likened our nerve impulses to a wind moving through the body (Frawley, 2000).
What is meant by the word Vitiation in the Ayurvedic system?

What is the word in the Ayurvedic system for nervous system disorders?
vata vyadhi (meaning vata disorder)
In the Ayurvedic system, what is are the two main cuases of nervous system imbalances?
Broadly speaking, nervous system imbalances are the result of either a blockage of the nerve impulses or weakened and depleted nerve tissue.
What are the causes of blockages of the nerve impulses in the ayurvedic system?
Blockage of the nerve impulses can be due to an excess of any of the three doshas: vata, pitta, or kapha, as well as accumulation of ama (undigested food or experiences).
What are the causes of weakening of the nerve tissue, within the Ayurvedic system?
Wasting or weakening of the nerve tissue is usually due to vata or pitta excesses. Vata dosha, which is cold, light, dry, and mobile, has a way of depleting any bodily tissue that it invades. Also, vata tends to move into empty spaces. So, areas of the mind and body that are left porous by deficiency or loss become easy hosts for vata dosha. Pitta dosha, with its strong and potentially destructive heat, has a way of causing depletion by burning tissue up (Frawley, 2000).
Explain the 5 sub doshas of Vata
Prana vayu is located in the head and centered in the brain. Prana vayu draws energy into the body through the five senses (Halpern, 2012). Prana vayu is also the motivating force behind the acts of inhalation, swallowing, sneezing, spitting, and belching, which are incidentally actions centered in the head, throat, and upper chest region (Frawley, 2000).
Udana vayu, located in the chest and centered in the throat, governs all upward and outward moving actions of the body. It is the upward and outward wind. Udana vayu is also connected to our muscle tissue, and a healthy udana vayu expresses as strong memory, strength, and ability to carry out our will in the world (Frawley, 2000). It may be worth noting that in order for muscles to move, nerve impulses are required.
Vyana vayu is centered in the heart and governs the circulatory system as well as the movements of the joints and muscles. Vyana vayu is referred to as the diffusive or pervasive air, largely due to its involvement in circulation (Frawley, 2000).
Samana vayu is based in the small intestine and governs the nerve activity that is involved in digestion (Frawley, 2000). Digestion isn’t just an interplay of microbiota, enzymes, and acids. The enteric nervous system pervades the gut (Enders, 2015) and is the house of samana vayu.
apana vayu is the downward moving air. Its center is the colon and is responsible for all processes of elimination, such as menstruation, urination, ejaculation, and excretion (Frawley, 2000).
What kinds of food is recomended for those with a vata imbalance?
food that is warm, moist and heavy.
