I have been taking baicalein (from Chinese Skullcap) for about 10 days and have found some noticeable improvement in my hand tremor. I also feel my lip tremor is getting better. I am going to increase the dosage a little bit.

There are also some studies on baicalein in China and someone had filed a patent application using baicalein and other Chinese herbs for treating PD. It states baicalein is neureprotective and is efficacious for tremors. It is in fact a very popular herb med in China for treating infectious diseases.
