Shui Niu Jiao, which is a substitute for Xi Jiao advised in the source text, must also be substituted in the UK. Increasing Xuan Shen and adding Huang Lian to make a 3:1 ratio is the usual substitution.
Shi Gao must also be substituted which is harder to achieve.
Herbs like Sheng Di, Chi Shao and Mu Dan Pi are often added to the formula to increase its effectiveness so adding these may help but they are more Blood level herbs. Herbs like Huang Qin, Lian Qiao, Zhi Zi and Dan Zhu Ye may be more appropriate if the Qi level heat is strong.

Preparation: Decoction. The source text advises boiling the herbs in 8 cups of water until 3 remain which are taken warm througout the day. The dregs are then cooked once more with less water and taken again at night. Dosages may be adjusted according to the relative severity of Qi or Blood symptoms.

Actions: Clears Qi level Heat and cools the Blood

Contraindications: This formula is for a strong pathogen with a strong constitution and so it is contraindicated for people with Yang deficiency or weakness of the Spleen and Stomach
