You are herxing.
Samento is very powerful stuff. I have no idea what Cowden is putting in there but it is much more powerful than Cat's claw. For me it gave me huge neurologic herxes starting from up from 18 drops .And I dont usually have generalized joint pain (sometimes my right ankle is a bit sore) but when i took Samento every joint in my body started to hurt at the same time, i discovered i have joints even in places that i had no idea they had joint tissue before
During herxes, it is important to detox:
