(from Medicinal Mushrooms – A Clinical Guide by Martin Powell) Japanese name – Reishi or Mannetake (10,000 year mushroom / mushroom of immortality)
Chinese name – Ling Zhi (spirit mushroom – mushroom of spritual potency) The most famous of all the medicinal mushrooms, with annual sales of over US$2billion, G. lucidum’s wide ranging health benefits are due to its combination of high polysaccharide content (Stamets reports the fruiting body to contain 41% beta glucan) and wide range of triterpenoid compounds1-4. Over 130 of these have been identified, belonging to two families: ganoderic and lucidenic acids with functions including:
- Inhibiting Histamine Release
- Anti-hypertensive (ACE inhibiting)
- Inhibiting cholesterol synthesis
- Inducing apoptosis
- Inhibiting viral induction
- CNS sedation
- Immune modulation
Key Components – Triterpenes and polysaccharides
Dose – Chang reports the daily dose in folk use for cancer as 25-300g/day fruiting body as decoction (aqueous extract)52, and cases of spontaneous remission have been reported using similar doses. Concentration ratios of extracts vary with most in the range of 12-18:1. Taking an average concentration ratio of 15:1, this equates to 2-20g/day of extract, with most practitioners using the lower end of the range, in the region of 3-6g/day. For other conditions lower doses in the range of 1-3g /day are usual.
Levels of both polysaccharides and triterpenes are highest in the fruiting body and are traditionally extracted by hot water extraction (i.e. boiling to make a tea). However, while aqueous extraction is ideal for the polysaccharides, which are highly water soluble, the triterpenes are poorly water-soluble but highly alcohol-soluble. As the polysaccharides are precipitated out of solution by alcohol some manufacturers have taken the step of supplementing polysaccharide-rich aqueous extracts with triterpenes obtained through alcohol extraction in order to combine the benefits of G. lucidum‘s polysaccharides and triterpenes.
Caution – Patients on anti-hypertensive and sedative medication. G. lucidum‘s anti-coagulant properties mean that caution is also required when using it alongside anticoagulant drugs53. 1. Reishi mushroom: herb of spiritual potency and medical wonder. Willard T. 1990. Pub. Sylvan Press
