Adaptogens
Herbs help increase the body’s resistance to stress. They improve the body’s resilience by enabling it to physiologically adapt to problems before it reaches the point of collapse. An inability to cope with external pressures can have many health repercussions. They appear to work by supporting the function of the adrenal glands.
Alternatives
herbs that gradually restore proper function to the body, increasing health and vitality. Some of these herbs support waste elimination processes via the kidneys, liver, lungs, or skin. Others stimulate the digestive function of providing antimicrobial actions, while others simply work!
Anticatarrhal Herbs
Herbs help the body eliminate excess mucus, whether in the sinuses or from other parts of the body.
Anti-Inflammatory Herbs
Herbs with anti-inflammatory properties soothe inflammations or directly reduce the inflammatory response.
Antimicrobial Herbs
Help the body destroy or resist pathogenic microorganisms. They help the body strengthen its own resistance to infective organisms and throw off the illness.
Antispasmodic Herbs
Antispasmodics ease muscle cramps. They alleviate muscular tension and, as many are also nervines, can ease psychological tension as well. Some antispasmodic herbs reduce muscle spasms throughout the body, and some work on specific organs, systems, or types of tissue.
Astringents
Herbs have a binding action on mucous membranes, skin, and other tissue, which translates to an ability to shrink tissues and reduce secretions. These actions are related to the presence of chemicals called tannins, so named because they are used in taking leather. They precipitate protein molecules, reducing irritation and inflammation and creating a barrier against infections that is helpful in wounds and burns.
Bitters
Bitter-tasting herbs play a special role in preventive medicine. The bitter taste triggers a sensory response in the central nervous system, which sends a message to the gut. The gut in turn releases digestive hormones that lead to a range of effects, including stimulation of appetite and general stimulation of the flow of digestive juices. They also aid the liver in its detoxification work increase bile flow and stimulate gut self-repair mechanisms.
Cardiac Remedies
This is a general term for herbs that have beneficial actions on the heart and circulatory system. Some of the remedies in this group are powerful cardioactive agents, such as foxglove, while others are gentler, safer cardiotonic herbs, such as hawthorn and motherwort.
Carminatives
Plants rich in aromatic volatile oils, or carminatives, promote appropriate digestive system function, soothing the gut wall reducing inflammation, easing griping pains, and helping the body eliminate gas from the digestive tract.
Demulcents
Herbs high in mucilage, known as demulcents, soothe and protect irritated or inflamed tissue. They reduce irritation throughout the length of the bowel, reduce sensitivity to potentially corrosive gastric acids, help prevent diarrhea, and alleviate the muscle spasms that cause colic. They also ease coaching by soothing bronchial tension and relax painful spams of the bladder.
Diaphoretics
They promote perspiration, helping the body to eliminate wastes through the skin. some produce observable sweating, while others enhance normal background perspiration. They often promote dilation of surface capillaries, thus helping to improve poor circulation. This action is especially relevant in the treatment of fever.
Diuretics
Herbs that increase the production and elimination of urine. In herbal medicine, with its ancient traditions, the term is often applied in a general way to herbs that have a beneficial action on the urinary system. They help the body eliminate waste and support the whole process of inner cleansing.
Emmenagogues
Herbs stimulate menstrual flow and function. In most herbals, however, the term is used in a wider sense to indicate a remedy that normalizes and tones the female reproductive system.
Expectorants
Herbs stimulate the removal of mucus from the lungs, but the term is also often used to refer to respiratory system tonics. There are two basic categories of these types of herbs.
Stimulating expectorants irritate the bronchioles, causing expulsion of material.
Relaxing expectorants soothe bronchial spasms and loosen mucous secretions, helping with dry, irritating coughs.
