Very effective--watch dose

Posted by iHerb Customer on Oct 29, 2011 | Verified Purchase

This Sinus formula worked very well to dry up my sinuses, and after the second dose I coughed up a thick string of mucous which would have rattled around in my throat if this formula had not enabled me to cough it up. But I would slow down on taking this after the third dose because after my fourth dose, my sinuses were way too dry and I had to moisturize them with a nasal spray.

Thanks for your feedback!

Clarification of "lead"

Posted by iHerb Customer on Apr 10, 2009 | Verified Purchase

For a balanced look, one can go to and click on "CALIFORNIA PROPOSITION 65 WARNING LABELS" at the top of the home page for more information on the "lead" mentioned in prior review. Most likely you will conclude that the "lead" warning is only for trace amounts of something commonly found naturally in fruits, vegetables and herbs.

Not So Great

I generally love Dr. Shen's products. I never run out of yin chiao in the winter. These sinus tablets, however, don't seem to have any effect.
