How do you do a parasite cleansing and is it worth it?

Parasite cleanses are an unproven alternative approach to medicine. Alternative and complementary medicine approaches can be very helpful in managing our health, but cleanses and detoxes for various issues are among the most controversial, and are not backed by scientific evidence through rigorous research studies. They involve dietary changes and a variety of supplements. The cleanses often cause diarrhea (sometimes severe) and may interact with medications you are taking.
