Part of the problem is that Acne has nothing to do with parasites. And the same applies to most of what Hulda Clark claims. There are a few parasitical cancers, but they are extremely rare.

Acne is caused from androgens and bacteria on the skin. The bacteria is always going to be there as it is a natural part of the body. So Acne needs to be addressed internally. I recommend using digestive bitters to cleanse the liver. This will allow the liver to do its job of breaking down the androgens properly. Bitters are bitter tasting herbs sold in health food stores. When they contact the bitter receptors on the tongue they stimulate the vagus nerve. This in turn causes the liver to flush. Recommended amount is 1/2 dropper full twice a day right before meals on the tongue. Remember to drink a lot of water throughout the day when using bitters. They are sold in health food stores under names like Grape Bitters and Swedish Bitters.

Zinc also helps with the proper breakdown of androgens. Recommended dose is 50mg a day with your largest meal to help prevent nausea. A B complex is also recommended since the liver requires B vitamins to metabolize hormones.
