Fei Er Wan is a 8-ingredient Chinese Medicine formula with Quisqualis Fruits (Shi Jun Zi) and Areca Nuts (Bing Lang) as principal ingredients.

 

Invented in 1156 AD, it belongs to the category of formulas that reduce food accumulation and transform Stagnation. Its main actions are: 1) kills parasites and 2) reduces accumulation.
