Hmm, the random spots on the face and lip would of made me doubt parasites too, until recently...i too get tiny wriggles in my lip from time to time. And it's not a muscle spasm. Try to pay very close attention to what your "muscle twitches" feel like. Is it like a quick, even pulse? Or...imagine an earth worm. Surely you've seen one before? Image how it moves; kind of constricts and rolls in that wormy way (gross, i know). Does it feel kind of like that? Keep in mind that Tapeworms are known for hanging out in muscle. I find it highly unlikey that the herbs damaged anything, but rather the herbs disrupted the worms you have scattered, causing them to swirm/move. This is very common with cleanses that target them. I, for example, had NO IDEA I was harboring worms until I started Clark's parasite cleanse (on a whim). It caused one large one to move. My scattering happened later, but now when I am doing something that is effecting them, they make themselves known throughout the body by "twitching" or squirming. Of course, I would never suggest you ignore what your instincts tell you, but just know that what you are experiencing is very common during para cleansing.
