Antrodia camphorata (Antrodia cinnamomea)
(from Medicinal Mushrooms - A Clinical Guide by Martin Powell)
Taiwanese name - Niu Chang Chih
This native Taiwanese mushroom is starting to attract interest because of the exceptionally high concentration of its triterpenoid compounds and their structural diversity. Other important bioactive compounds include polysaccharides, maleic/succinic acid derivatives, benzenoids and benzoquinone derivatives1-4. In the wild A. camphorata grows solely on the tree Cinnamomum kanehirai, a species of cinnamon that grows at altitudes of between 450 and 2,000m in the mountains of Taiwan. As the fruiting body only develops fully once the tree is dead, in the past many trees were felled to supply demand for this unique and extremely lucrative mushroom (wild A. camphorata fetches up to US$15,000/kg) and this, coupled with the fact that C. kanehirai itself is highlysought for furniture manufacture, has led to over-exploitation, with the result that C. kanehiraiis now protected by the Taiwanese government5.
To replace the wild-collected material, commercial cultivation of A. camphorata has been developed using a variety of techniques to produce either cultivated fruiting body, pure mycelium (grown by liquid fermentation), or mycelial biomass (mycelium and residual substrate). Levels of triterpenes are highest in the fruiting body products, which are also the most expensive, and lowest in the mycelial biomass products, with liquid fermentation mycelial products offering a cost-effective intermediate option. A. camphorata has a wide range of traditional indications, including alcohol intoxication, cancer, hypertension, fatigue, viral infection and liver disease1.
HEPATOPROTECTIVE - The use of A. camphorata by Taiwanese natives to counterthe adverse effects of excessive alcohol consumption was first reported by traditional Chinese medicine doctor Wu-Sha in 1773. In animal experiments both the fruiting body and mycelium have been shown to protect against alcohol-induced hepatitis and liver steatosis (fatty liver), as well as CCl4 and cytokine induced liver damage, ameliorating increases in AST, ALT and ALP levels and histopathological changes in a dose-dependent manner with no observed lesions5-9. A. camphorata fruiting bodies also inhibited alcohol-induced rises in cholesterol, hepaticlipids and liver enzymes in rats with moderate effect at a dose of 0.025g/kg and increased efficacy at a dose of 0.1g/kg10-12.
Separately it has been shown that A. camphorata possesses strong antioxidant activity and it has been suggested that this is a major contributor to its hepatoprotective properties13,14. Its antioxidant activity is correlated with the presence of total polyphenols, crude triterpenoids and the protein/polysaccharide ratio of the polysaccharide extract15. A. camphorata polysaccharides also show hepatoprotective and anti-hepatitis B activity16,17,while a number of maleic/succinic acid derivatives showed potent inhibitory activity against hepatitis C protease through competitive inhibition18.In addition A. camphorata has been shown to suppress the invasive potential of liver cancer cells through inhibition of NF-kappaB19 and to induce apoptosis in human hepatoma cells20-23.
CANCER - As well as its effects on liver cancer, multiple in vitro and in vivo studies show inhibition of cancer cell growth and migration, together with increase in apoptosis, invarious cancer cell lines including breast, prostate, liver, bladder, cervical and oral carcinoma1,24-29.
ASTHMA - The immune modulating and anti-inflammatory actions of A. camphorata offer potential in asthma treatment with animal experiments showing that A. camphorata polysaccharides dose-dependently inhibited the development of airway hyper responsiveness, airway eosinophilia and Th2 immune status30.
SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) - A mycelial extract of A. camphorata reduced urine protein and creatinine levels and suppressed changes in the kidney glomerular basement membrane (a histological hallmark of SLE) at a dose of 400mg/kg in a mouse model of SLE, suggesting ability to protect the kidney from autoimmune disease31,32.
CARDIOVASCULAR DISEASE - A. camphorata has traditionally been used to treat avariety of heart conditions, including hypertension and atherosclerosis, and A. camphorata extracts have been reported to inhibit thickening of blood vessel walls and to promote vasodilation33,34.
Main Therapeutic Application - Liver disease.
Key Component - Triterpenes, Polysaccharides.
Dose - While the more expensive fruiting body contains the highest level of triterpenes and is preferred in Taiwan for cancer treatment, mycelium produced by liquid fermentation is increasingly available and has been shown to offer a cost effective alternative for treatment of liver conditions, with a recommended dose of 1-3g/day.
Caution - Patients on anti-coagulant medication.
