Anyone know where I can find 250ml bottles of Gold Coin Grass? I believe it's also known as 'Jin Qian Cao' or 'Chin-chien Tsao', (depending on dialect, I suppose).

This is traditional Chinese medicine used for flushing the gallbladder and liver.

I'd also be interested in finding Chinese bitters.

I do not know if this product is available in Thailand.
