This is just one of quite a few remedies which cost very little yet are highly effective for many if not most health issues. A few more examples are fasting, colon cleansing, urine therapy, magnesium & borax supplementation, FIR sauna. The first three, and MMS (and there are others) even on their own can cure many so called incurable diseases. If you combine a few, then immune system can be so strong ine might never get ill, and can live a much longer healthier, happier, and abundant life as a result.
There are no magic bullets though, and most essential is to deal with our "emotional" blockages, otherwise even if we cure one disease another will come back to poke us to help wake us up. The root cause of ALL dis-ease is the belief in the false sense of I, the cause of all suffering.
May peace be with you brother.
