The ancient Chinese referred to these mushrooms as "Spirit Medicine", a text from 2838 BC claimed it was the most valuable herb. A long history of use has produced much anecdotal evidence of beneficial health outcomes for those lucky enough to have access to this plant.
Commonly called Reishi or Lingzhi these mushrooms are rare in the wild and very highly prized. Nowadays they are cultivated organically indoors and the company I deal with have invested much time and effort in growing and processing the mushroom to protect the high concentrations of Polysaccharides, Triterpenes, Organic Germanium and nearly 200 other active ingredients.
A search on the internet will show many claims about the curative properties of this mushroom but until those claims can be backed up by "rigorous scientific research", in Australia it must be regarded only as a dietary supplement which may help in promoting general well being.
If you have or suspect that you have a medical problem, you should seek advice from a health care professional.
