A popular gourmet mushroom, G. frondosa is also a highly regarded clinically, especially in cancer therapy.

As with other major anti-cancer mushrooms such as Lentinula edodes (Shiitake) and Trametes versicolor (Coriolus), polysaccharides have been shown to be the major active components of G. frondosa and several beta-glucan, heteropolysaccharide and proteoglycan fractions have been isolated with potent immuno-modulatory action, including D-fraction and MD-fraction1-5.

Most of the clinical research has been carried out by one group of researchers in Japan, initially using D-fraction together with powdered fruiting body, later switching to the more bioactive MD-fraction, again in combination with powdered whole fruiting body.

CANCER - A 1997 paper by Nanba reported benefits from D-fraction taken together with whole fruiting body in a range of stage III-IV cancers with G. frondosa increasing the benefit of chemotherapy by an additional 12-28%6. The paper further reports synergistic benefits from combining D-fraction and Mitomycin C (MMC) in an animal tumour model with D-fraction (1mg/day) showing superior tumour inhibition to MMC (0.5mg/day) on its own.

A subsequent paper by Nanba et al reported impressive results for MD-fraction and whole G. frondosa fruiting body powder in cancer patients who had discontinued chemotherapy because of side effects with improvement in seven of 12 liver cancer patients, 11 of 16 breast cancer patients and five of eight lung cancer patients, together with increases in IL-2 (a major Th1 cytokine) and CD4+7.

Further studies confirmed alleviation of side effects from chemotherapy, including loss of appetite, vomiting, nausea, hair loss and leukopaenia, as well as synergy between D-fraction and vitamin C2,7.

DIABETES - Various animal studies indicate benefit from G. frondosa in diabetes models but at high doses, in one case giving 1g/day G. frondosa powder to genetically diabetic mice and in another a purified alpha-glucan at a dose of 150-450mg/kg8,9.

In small scale clinical studies G. frondosa polysaccharide extract (dose unknown) was reported to control blood sugar levels in one patient and produce a 30% reduction in blood sugar levels in 4 other patients while inclusion of G. frondosa beta-glucans (150mg/day) in yoghurt produced significant improvement in blood glucose levels in 20 type II diabetes patients3,10.

POLYCYSTIC OVARY SYNDROME (PCOS) - In the majority of cases, PCOS is associated with some level of insulin resistance and G. frondosa polysaccharide extracts also show promise as agents for helping address this condition11.

In one Japanese study, ovulation was observed in 20 of the 26 women given a G. frondosa polysaccharide extract and six of eight women who failed to ovulate after being treated with clomiphene citrate did so after being given the polysaccharide extract. In addition, all three women who expressed an interest in becoming pregnant were able to do so12.

CHOLESTEROL - Inclusion of G. frondosa in the diet of experimental animals at 5-20% of feed produces reductions in cholesterol consistent with the results seen in other mushrooms13.

HYPERTENSION - A number of studies report short-lived hypotensive action for G. frondosa included in the diet of hypertensive animals (typically 5% of feed)14-16.


Main Therapeutic Application - Cancer, PCOS.

Key Component - Polysaccharides.

Dose - The optimum dose of D-fraction/MD-fraction in animal studies is reported to be 1mg/kg i.p. with human trials using D-fraction/MD-fraction at oral doses of 35-150mg/day in combination with 4-6g/day G. frondosa fruiting body.
