A clinical study by Hong Kong Baptist University has discovered what may prove a breakthrough in the treatment of Parkinson's disease.

Researchers found that a traditional Chinese prescription medication, uncaria rhynchophylla, or gouteng, in use for more than three centuries, has proven effective in treating Parkinson's disease without the side effects prevalent in Western medication.

Li Min, an associate professor who led the research at the School of Chinese Medicine at the university, announced the results on Wednesday.

The study shows that the prescription can relieve non-motor symptoms of Parkinson's disease, such as depression, sleeping disorder, constipation and loss of appetite.
