Ingredients
Ren Shen 3-6g
Bing Lang 9g
Chen Xiang 3-6g
Wu Yao 6-9g

Subsitutions:
In UK Bing Lang must be replaced. Zhi Shi and Yu Li Ren are the standard replacements but unless constipation is a symptom the latter seems inappropriate. Zhi Shi will still direct the Qi downward and if a second herb is needed maybe Gua Lou to open the chest and dissipate accumulation.

Actions: Promotes movement of Qi, directs rebellious Qi downwards, expands the chest, dissipates clumping

Contraindications: Long term, significant deficiency of normal Qi
