Sure, you can and probably have had parasites
your whole life. They obviously have gotten bad enough to affect you now. The parasites
rarely hurt much--it's their infections, and yours might not had any. And laxatives would have no effect on a ball of parasites---The herbs she recommends would, especially Wormwood
, it would just break the ball up and send them wriggling them out of your digestive system--which really wouldn't help for long.
You need a zapper. Heck, just make the simple one she tells you how to build, for now and get the parasites
killed. There's issues with zappers right now in the US and Europe, so if you want to order one, make sure it's made elsewhere. They're very easy to make, so other areas of the world should do just fine.
And you may or may not see them. They break down pretty fast and unless they're right at the end, they'll be gone. Never use that as an indicator of infestation. If you have symptoms as outlined by Dr. Clark, that's really the only way to tell, although any more, you can just assume you have them. Their eggs are everywhere; you'll get them---have no fear.
