Start by balancing your biological terrain first. A clean, healthy Diet that alkalinizes ans supplies a wide array of mineralizes is critcal. I prefer raw vegan for this for a variety of reasons.
Also cleansing your body to remove congestion and then stored toxins will be another crucial step. This includes bowel cleansing as well as Liver Flushing and cleansing.
You will also want to deal with parasites that are almost certainly dweeling in your current swamoy terrain.
All these steps taken together will allow the body to heal itself.
