Reishi/Gano/Lingzhi is a basidiomycete, lamellaless fungus belonging to the family of polyporaceae. In nature, it grows in densely wooded mountain of high humidity and dim lighting. It is rarely found since it flourishes mainly on the dried trunks of dead plum, guercus serrata or pasonia trees. Out of 10,000 such aged trees, perhaps 2 or 3 will have Reishi/Gano/Lingzhi growth, therefore it is very scarce indeed. The spores of reishi have such tough outer husks that germination is next to impossible and this accounts for its rarity. It was said that in the old days when one discovered Reishi/Gano/Lingzhi, it had to be kept a secret even from one's closest relative and there was big celebration upon fruitful return. The herballous history of Reishi/Gano/Lingzhi had long been documented in the oldest Chinese pharmacopoeia written in about the first or second century B.C.. In it Reishi/Gano/Lingzhi had been recorded as having the most extensive and effective healing powers. It is because of this recognition that there is diligent research for methods of Reishi/Gano/Lingzhi cultivation feasible for commercial productions. At about 1972, the cultivation of Reishi/Gano/Lingzhi became successful and as a result, what was once only attainable by the privileged is now readily make available to everyone. A number of countries are now conducting sophisticated research in Reishi/Gano/Lingzhi hoping to further the practice and science of medicine. The booklet reports the result of such research.
