Herbs that Dispel Wind-Dampness

Sang Ji Sheng (taxilli herba) treats bi syndrome, but by which way?

There are generally three treatment strategies for dealing with bi syndrome: (1) expel wind-cold-dampness, (2) smooth, stretch, relax, and unblock the channels, (3) tonify Liver and Kidney yin. Sang Ji Sheng is sweet in flavor and tonifies the Liver and Kidneys, making it especially useful for elderly or debilitated patients.
