The low doses in this formula indicate a mild pattern. For more severe presentations individual herbs may be increased. Since Ma Huang is below the legal limit of 1.8g per day and a maximum dose of 0.6g per administration this does not need to be substituted but if it is to be increased it must be done with other warm exterior releasing herbs like Zi Su Ye, Jing Jie and Fang Feng.

Preparation: Decoction.

Actions: Releases the Exterior and dispels Wind-Dampness

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.
