Lignosus rhinocerus (Tiger Milk mushroom) is distributed in South China, Thailand, Malaysia, Indonesia, Philippines and Papua New Guinea. In Malaysia, it is the most popular medicinal mushroom used by the indigenous communities to relieve fever, cough, asthma, cancer, food poisoning and as a general tonic. In China, this mushroom is an expensive traditional medicine used to treat liver cancer, chronic hepatitis and gastric ulcers. The sclerotium of the mushroom is the part with medicinal value. This rare mushroom has recently been successfully cultivated making it possible to be fully exploited for its medicinal and functional benefits. The present study was carried out to evaluate the chronic toxicity of the sclerotial powder of Lignosus rhinocerus cultivar (termed TM02), its anti-fertility and teratogenic effects as well as genotoxicity.
