This is the only brand I could find with bloodroot tincture, no other brand to compare. There are particles in the tincture, but I think it's normal for plant root. It works for what's it supposed to be. I wish the regular price is less expensive as I bought it when it's first promoted, after that the regular price is double, a bit too much to afford.
This product seemed to be effective within days of use. Symptoms did begin to abate very quickly without any side effects apart from a little irritation of the throat that was alleviated by flushing with water.
