Brief Summary

Lingzhi(Ganoderma) is widely used in traditional Chinese medicine. Previous studies indicated that Lingzhi was safe, well tolorated, and improved symptoms as an add-on therapy to levodopa in early Parkinson's disease(PD) patients. Here the investigators design a multicenter, randomized, double-blind, placebo-controlled, delayed-start trial to evaluate the effects of Lingzhi on modifying disease progression in untreated PD patients.
