Chinese Herb Notes
- Chuan Mu Tong and Hu Po both drain fire from the Heart Channel and Small Intestine with pain or bloody urine. Both drain fire from the Heart but Chuan Mu Tong is more used for sores on the tongue while Hu Po calms spirit.
- Mu Tong can be sourced from both caulis akebiae and clematis armandii, but clematis is more common in the United States.
