I am experiencing the same symtoms! I have just started the Clarkia tincture. Its been just over a week now. I have started having headaches and seem to have broken out in adolescent spots too! Someone suggested that it may be the toxins releasing from the dead parasites.
I hope I am using this stuff properly. I bought it with a view to eventually doing the liver cleanse, and was strongly advised to do a parasite cleanse first.
I live in the United Kingdom and I know of no-one here who uses this tincture. I feel horrified when I read about the parasites that some people have discovered. Can they really be living inside your gut? Watch this space!
