In the UK Shi Gao and Shui Niu Jiao (itself an alternative to Xi Jiao advised in the original) must be substituted. The typical replacements for Shui Niu Jiao are already in the formula (Xuan Shen and Huang Lian) as are almost all herbs to clear Heat from the Qi level making them hard to replace except by raising the dose of the existing herbs or adding any that address any specific symptom variations of this pattern.

Preparation: Decoction. The Shi Gao and Shui Niu Jiao should be decocoted for 15-20 minutes before the other herbs.

Actions: Clears Heat, resolves Toxicity, cools the Blood, drains fire

Contraindications: Yang deficiency or weakness of the Spleen and Stomach
