I have 3 packs of 100% monkey bezoar powder (hau cho shan) until to Dec 2007 from Eu Yan Sang. This one can clear away excessive phlegm, relieve cough and ease breathing, suitable for infants suffering from chronic cough. Especially for the bb around 1.5 years old or elder. The original price is $100 each now 3 packs is $240, if anyone have interest, pls pm me. Thx!
