Traditional uses
The bark with white latex threads when snapped. Used for low-back weakness and a cold picture of kidney yang. Some textbooks also group it with erectile difficulty when the low back is weak and cold. That prenatal “calm the fetus” use you may see elsewhere is prescriber territory, not a tea. Not a treatment for ED.
Common pairings
- Shu Di Huang 熟地黄
Yang and yin support together so warming is not empty.
- Rou Gui 肉桂
Two warmers. Rou Gui is hotter and more internal.
Cautions
Not for self-dosing. Care in pregnancy except under a licensed prescriber. Not for a hot, excess low-back injury. Can affect blood pressure in some reports.
