Abstract
Parkinson's disease is a slowly progressive degenerative disorder of the central nervous system. It is characterized by tremor when muscles are at rest, increased muscle tone, slowness of voluntary movements, and difficulty maintaining balance. In oriental medicine, these symptoms are diagnosed as yin(陰)-deficiency of liver and kidney, deficiency of qi(氣) and blood, retention of phlegm(痰), qi-stagnation and blood stasis. In this case, we diagnosed patients as deficiency of qi(氣) and blood type according to symptoms and treated by herbs that strengthen yang and benefiting yin for two weeks, while maintaining existing parkinson's western medication. After treatment, clinical symptoms were improved, while UPDRS (Unified Parkinson's Disease Rating Scale) score was decreased. These cases suggest that oriental medicine therapy maybe effective in the treatment of Parkinson's disease.
