Bi Yan Pian Formula 2 oz

I use this stuff everytime I get gunk in my chest. Works great. Taste not so good but I just add it to orange juice or something else.

None of the over the counter pills have worked as well as this. Summer allergies have been a problem all my life, but this helps where nothing else has. Bitter flavor is a hurdle to get past.

Take it when you start feeling congested and you'll be good in no time. It is bitter so take it with a bit of water.
