Traditional uses
Cooked gypsum is the textbook mineral for a yang-ming heat pattern: high fever, sweat, thirst, and a flooding pulse, in the old descriptions. That picture overlaps real emergencies. It is not a home fever powder.
Common pairings
- Zhi Mu 知母
The pair inside Bai Hu Tang: mineral clears, Zhi Mu protects fluids. Hospital-level patterns, not a tea.
Cautions
Not for self-dosing. Very cold. Do not use it to sit out a high fever. Mineral identity and preparation matter.
