They're called Er Chen Teapills by Plum Flower. They're also sometimes referred to as Er Chen Wan. They do help him but he'll still sometimes have sneezing attacks and I also sometimes notice that he's making some noises when he breathes. If he wasn't taking them he'd be a lot worse.

I put them in part of a chicken pill pocket and he now begs for his pills. I give them to him in the morning and then in the evening so he gets 2 pills a day. I think it took several weeks for me to notice a difference. Certain times of the year he's much worse than others though.

I originally got them from my holistic vet but you can also buy them online at this website: http://www.chineseherbsdirect.com/er...wan-p-337.html. Good luck.
