Review: Effective at reducing histamine - Effective, easy to take, taste is pleasant, effective for reducing histamine.
Review: Really helping! - I bought this to use on my all-white young cat with blue eyes that I got from the Humane Society. I understand that these white cats tend to have more health problems. She had bad sneezing, runny eyes, and developed scabs on her body. The vet gave her a steroid injection and some cream for her ears that were crusty, but I didn't want to keep going back to the vet, so I researched what I could do on-line, and besides, the vet's work didn't help much. Now I've been giving her powdered L-Lysine in her food, spraying Vetericyn on her ears (purchased from a farm supply store), and am using the Quercetin, one dropperful a day. After about a month on this regimen, she's almost perfect! No sneezing, her ears are MUCH better, and the scabs on her body are practically gone!

### ⭐⭐⭐⭐⭐ Not the same as the photo. Not as good as before.
*by Z***L on November 18, 2016*

These are not as pictured. They have two holes instead of one and are very hard to work with compared to the previous single hole design. In this double-hole bag, it's hard to open the neck to pour the water in. And the clip falls off if it is not in the closed position so if you want to let it dry on the inside to reuse, the clip falls off. The previous model had a single hole so it could hang easily on a hanger. And the clip stayed on in either the open or closed position. And it was easier to pour the water in. I hope they bring that enema bag back.
