Dose:


Decoction: the above can be taken over the course of a day. In Powder: 3–6 grams twice daily (taken after meals if the stomach is weak or sensitive).

Cautions:


This is a Cold and Drying formula. It will harm the Spleen and for this reason is disliked by some TCM practitioners, especially of the ‘Earth School’. However, used as powder or pills it is far better tolerated and less likely to be so draining, yet is still markedly effective. It is still not used in Qi deficiency or Yin deficiency.

Modifications:


1. I find this better with Safflower (Hong Hua) added. Safflower opens the finest channels of the Liver to carry the other medicines deeper into the Liver organ. In addition, it counters the effect cold herbs have on capillary circulation, that is, to suppress it. Safflower is also accounted as the primary Liver medicine of the Six Excellent Medicines in the Tibetan Tradition.
2. The addition of Costus
Mu Xiang and Atractylodes Bai Zhu helps counter the cold effect on the Spleen.
3. Taken with
Si Wu Tang to nourish the Blood while simultaneously clearing Liver Heat. This is very useful in skin conditions with heat, but in someone who may still be pale faced and blood deficient. Useful for Acne, Eczema etc.

This is an extremely useful formula and is far better suited and more gentle in effect when used in pill or powder form, the decoction being reserved for strong Liver Heat conditions.
