A study has indicated that Chinese herb can help treat Parkinson's disease.

The results showed that volunteers who had taken the herbs slept better and had more fluent speech than those taking the placebo.
Now, Li Min, a traditional Chinese doctor at Hong Kong Baptist University and her colleagues have figured out how it might work.
Parkinson’s symptoms, such as muscle tremors, slowness of movement and rigidity, are caused by the progressive destruction of brain cells that produce dopamine.
According to Li, autophagy - a type of programmed cell death is the only known process that gets rid of abnormal proteins within cells.
"Enhancing this pathway may be key to treating Parkinson’s," she said.
