The mantle of the skin is a fatty layer that maintains an acid layer. Soaps and shampoos destroy the fatty layer leaving the acid layer exposed, which is then neutralized by soaps also. The apple cider vinegar helps to restore the acid layer. The tea tree oil has antifungal properties.
The antifungal drugs will harm the liver and other tissues. They check liver values to make sure that there isn't already existing damage. Either way, the drugs will cause damage. Whether or not that shows up on subsequent lab tests can depend on several factors, but the damage will take place.
Most skin conditions involve a lack of sufficient Hydrochloric acid (HCL) levels in the stomach. Supplementing with HCL can help the skin and the entire digestive tract. I would advise following our HCL Protocol.
In 2003, the FDA mandated that all medical doctors do susceptibility testing prior to giving any type of antibiotic/antifungal. MDs are still not following this federal mandate. Antifungal drugs can cause fungal infections. This is the Paradoxal Effect.
