Well my experience with the Chaparro Amargo (Crucifixion Thorn) has been 100% positive - it really completely wipes out protozoa - and in my case more specifically, cryptosporidium.
When I started taking it, within about two days (30drops 2X day), I had absolutely zero symptoms left. Not only that, but I felt a great surge of energy and heat in my body. I was sweating in the night, and felt that toxins were really being expelled from my skin. The last remnants of those awful symptoms.
So I take it 7 days on, 7 days off. Actually, I didn't start taking it in time this week, waited a few days too long, and the symptoms came back. Which confirms that I must be loaded with cysts and that I have to do this continuously for a few more months.
Lineup, it really surprises me that you had no results with this herb - it is one of the most powerful herbs I've taken, really strong. And certainly the most powerful of all the ones I had tried against crypto - bitter Oleander
, chinese wormwood, etc. And even more efficient than the Alinia. Up to now, I had not been able to completely eradicate my crypto symptoms, but with Chapparro, no problem.
I sometimes wonder though, being a Mexican herb and all, if it doesn't have psychoactive properties - I've noticed a lot of agitation sometimes in me, very very vivid dreaming, and wonder if I can attribute it to the Chapparro.
Anyways, this is an herb I recommend highly. It has also been used to treat cancers.
