A pale-golden medicine created by Yun Gu to cure the parasite epidemic. It is a hundredfold concentrated essence that must be diluted—one drop in a full bucket of water. The patient drinks one bowl daily for three consecutive days. It forces parasites out of the body in a painful process but can eradicate the poison and restore the foundation. The herbal residues can be applied externally to festering wounds to accelerate healing.
