I just wanted to throw in the name Dr. Hulda Clark here. Part of her method is based on frequency to directly kill the parasites/viruses/bacteria. She even has a book specifically called "The Cure For HIV / AIDS". The books go into more detail and also include an herbal process to cleanse the organs.
For the ones with gallstones or liver stones, the liver flush is great and very simple to do.
