In the UK the maximum legal dose of Ma Huang allowed without prescription is 1.8g per day, and a maximum of 0.6g per administration. This makes it difficult to get the effects required. If necessary it can be substituted with Zi Su Ye, Jing Jie and Fang Feng.

Shi Gao must also be substituted. In this instance Zhi Mu may make a reasonable substitution, or other Heat clearing herbs depending on the presentation.

Preparation: Decoction. Shi Gao should be decocted separately first.
In order to mitigate the agitation causing effects of Ma Huang it may be fried in honey first and when decocted the froth removed from the surface with a spoon.

Actions: Induces sweating and clears Interior Heat
