Contraindications

Cautions

Cold and draining: not for Spleen deficiency with loose stool, for fluid damage in the late stage of a febrile illness, or for seminal emission from Kidney deficiency. Always decoct it wrapped. Only pharmaceutical-grade, asbestos-free talc is acceptable, and the powder must not be inhaled — do not dust it near the face of an infant, and keep it off broken skin.

Contraindicated in pregnancy: Used with caution in pregnancy — it is cold and drains downward; practitioner supervision required
