I bought some of that. I think it is also known as Chapparal in which there is some warnings about it but you will need to check that out. There is another Mexican herb that has shown effective and if you want the info on it, PM me.
yeah I know coptis - a very bitter herb in Chinese pharmacopea. I don't think it has any antiprotozoan properties though. I was taking Chinese herbal prescriptions for several months last year - some of them containing coptis (huanglian); but results have never been stable.
That's the thing - herbals (or now chemical drugs) decrease the symptoms, even eliminate them. But as soon as anything is stopped - then it's back to square one, or maybe not square one, but nothing is stable.
I just read your post about the Chaparro Amargo. I have Entamoeba Histolytica and would like to try it for that. I went to the web page that you listed and they are out of the tinture. Do you know if I can buy it elsewhere? Do you know of anyone that has had success eradicating Entamoeba Histolytica?
