Charred processed form of Sheng Di Huang (Rehmannia glutinosa root). Retains entry into the same Heart, Liver, and Kidney channels but with strengthened blood-cooling hemostatic action and moderated cold nature, making it suitable for blood-heat hemorrhage — hematemesis, hemoptysis, flooding and spotting — where unprocessed Sheng Di Huang would be too cooling.
Reference range for non-pregnant adults. Not a personalized prescription. Pregnancy, lactation, and pediatric use require specialist supervision.
Protective guidance only — when to avoid or use with caution. This block deliberately omits pregnancy, lactation, and pediatric dosing: any such use must be managed by a qualified TCM practitioner or appropriate specialist.
