Q

What does the mycelial network do

A

it’s a root-like network that releases enzymes and acids to externally digest dead organisms and move nutrients back into the lifecycle.

Q

What is the most important action of beta-glucans and what are they

A

Beta-glucans are soluble fibres that come from fungi/mushrooms. They stimulate immune cells (macrophages, neutrophils, NKC, etc) and support
- optimal immune function
- promote immunomodulation
- anti tumour activity

Q

Why are mushrooms useful in cancer prevention

A

Compounds in medicinal mushrooms such as beta-glucans and triterpenes are anti-tumour,
sterols are anti cancer,
and lectins prevent tumour proliferation.
Beta glucans also support optimal immune funtion.

Q

Are mushrooms safe to use with drugs

A

Mushrooms demonstrate no appreciable inhibition of CYP450 enzymes which breakdown/metabolise drugs - therefore possibility of interaction is unlikely.

Q

8 therapeutic uses of Reishi

A

Immune modulating: increases number and activity of immune cells

Anti viral: Triterpenes inhibit replication of EB Virus and Hep B, inhibit and reverse transcriptase in HIV

Anti inflammatory:Triterpenes are anti inflammatory and anti histamine. Healthy ageing

Anti coagulant: Ganoderic acids inhibit platelet aggregation, thinning blood.CV disease support

Benign prostatic hyperplasia: 5a Reductase inhibitor therefore blocks conversion of testosterone to DHT/prostate growth

Stress and sleep: Triterpenes have sedative action, calm NS, support sleep and relaxation

Blood sugar regulating: Ganoderic acids increase insulin secretion and decrease resistance. - T2DM and PCOS

GI disorders: promotes regeneration of the gastric and intestinal mucosa - intestinal permeability, IBD, Peptic ulcers, gastritis, GORD.
Prebiotic therefore disbiosis use

Nervous system disorders:

21
Q

What does erinacine in Lion’s mane have a stimulatory effect on

A

stimulates production of NGF - nerve growth factor - a protein required to regenerate and repair nerve tissue.
Powerful anti oxidant
Alzheimers, concussion, MS, Parknsons, peripheral neuropathies, cognitive decline.

22
Q

What is the recommended dose of lions mane

A

1-6g/day

23
Q

Turkey Tail - what are its key components and what are they used for

A

2 polysaccharide extracts - polysaccharide K (PSK) and polysaccharide-peptide (PSP) used as drugs in cancer patients. PSK widely used in Japan.

24
Q

What are the 2 therapeutic uses of turkey tail

A

Cancer: anti: proliferative, metastatic, angiogenic. Can induce apoptosis of cancer cells.
PSK and PSP improves survival when combined with conventional therapies and protects against mutations caused by radiotherapy.
Especially indicated in hormonally driven cancers.

Immune modulatory: increases macrophage, T-lymphocyte, NKC.
Anti-viral against viruses eg EBV, HIV, Hep B.
Normalises overactive immune syst (good for autoimmunity) - no effect on healthy but upregulates immune system in immunocompromised.

25
Q

What is the dosage for turkey tail

A

1-9g/day

26
Q

Maitake - what are its important constituents

A

beta-glucans, metalloproteins, lectins, enzymes, ergosterol

27
Q

What are 4 therapeutic uses of Maitake

A

Immune modulatory: beta glucans stimulate macrophages, NKC, increase Th1 lymphocytes.
Fatty acids inhibit COX-1 and LOX-2 - reduce inflammation

Cancer: immune boosting effect of beta-glucans
Alleviate side effects of chemo eg loss of appetite/hair, vomiting
anti metastatic and inhibits tumour growth

CVD: contains protease which prevents clot formaiton
reduces LDL and regulates RAAS (normalising BP)

Metabolic disease: proteoglycans improve insulin sensitivity. Useful for T2DM and can help induce ovulation in PCOS.
Good for fatty liver issues as hypolipidemic

28

40
Q

Which 2 mushrooms might be useful for regulating blood sugars

A

Reishi: ganoderic acids increase insulin secretion and decrease resistance

41
Q

Which 3 mushrooms might be helpful for CVD

A
