The cure must be based on scientific theories, not "remedies," and you have no way of knowing if it will cure you or not, and you don't know if it will be harmful to your body. And don't rely on medications like antihistamines, which my doctor told me won't cure it at all.
1. Watch your diet and take probiotics. Food that builds up in the body creates toxins that can trigger a lot of problems such as rashes.
2. Clean out your intestines. Activating the body's self-repair mechanism is the way to go! Our body has a very powerful self-healing function, it's just that many people don't activate it.
