Elucidation:
The syndrome is due to pathogenic factors invading shaoyang meridian and fighting against healthy qi in between the exterior and interior. Ingredient No. 1, as monarch drug, dispels the pathogenic factors located in the half exterior and restores the functional activity of shaoyang meridian. Ingredient No. 2 acts as minister drug to purge away heat located in the half interior. They are primary drugs for treating shaoyang disease, one for dispelling pathogenic factor, and the other clearing away the accumulated heat. Ingredients No. 5 and No. 6 can regulate the stomach and relieve vomiting, while ingredients No. 3, No. 4 and No. 7 supplement qi and strengthen body resistance to prevent the pathogenic factors from getting into the interior. These five ingredients play the role of adjuvant drug. Ingredient No. 4 coordinates the actions of various drugs in the recipe and also serves as guiding drug.

This recipe should be used with great caution for patients with shaoyang disease but manifesting deficiency of yin and blood because Ingredient No. 1 possesses lifting and dispersing action and ingredients No. 2 and No. 5 are of dry nature.
