Subsitutions:
In the UK several of these ingredients are illegal or hard to obtain. Gan Sui, Qing Fen and Bing Lang must all be replaced due to toxicity or legal reasons. In addition Yuan Hua and Qian Niu Zi are not commonly available. These all have the strong purgative actions that make this formula what it is and their removal will change the formula to have a gentler action. Replacing them with Qian Niu Zi and/or Ting Li Zi or Wu Ling San and Da Cheng Qi Tang with Yu Li Ren instead of Mang Xiao is probably the best substitution. It may make for a gentler formula aimed at a milder presentation but still quite strong by the standards allowed in the UK and people with the original presentation are best referred to a hospital.



Preparation: Ground into powder and formed into pills with water. Taken in 3-6g doses with warm water on an empty stomach in the early morning. If the condition improves and the patient remains strong it may be taken again with a reduced dosage 1-2 days later, otherwise it should be taken only once.

Actions: Promotes the movement of Qi and harshly drives out water and Heat accumulation

Contraindications: Pregnancy and in persons who are weak and debilitated. Gan Cao is also contraindicated to Gan Sui. Due to the toxicity the dosage and administration should be carefully monitored and the formula changed to Spleen and Kidney tonics once the acute condition has resolved.
