Commonly called the Ling-Zhi in China and Reishi in Japan. This species is one of the bracket fungi, but unlike most species, typically has a long slender stalk that attaches to the side of the "cap" of the fruiting body. This is one of the great longevity tonics of Chinese Medicine used in cancer treatment .
Reishi enhances immune response, alleviates chemotherapy side effects such as nausea and kidney damage. A number of anti-cancer constituents have been isolated from G. lucidum. These compounds have demonstrated antitumor and immunostimulating activities.
Various studies showed that Reishi, restricted blood vessels to prostate cancer tumours and stopped cancer cell proliferation. Anticancer effect of Ganoderma lucidum has been studied alone or in combination with chemothereupatic drugs as well as radio therapy effectively.
Ganoderic acids A and C from G. lucidum are inhibitors of farnesyl protein transferase, an enzyme that participates in Rasdependent cell transformation. Inhibitors of this enzyme represent a potential therapeutic strategy for the treatment of cancer .
The proliferation, maturation and activities of both T and B lympocytes, NK cells and dendritic cells improved significantly during both lab and animal tests when taking Reishi. Beta-glucan is the most constituent for immune support.
