For herbs to be effective they need to be fresh and not polluted with impurites as many are. I encourage herbal healing, but with the proper herbs which you do not get with many of todays supplements. If one can find fresh and pure herbs and knows how to take them then by all means I encourage people to do so.
A healthy body also produces what is called systemic enzymes that will destroy parasites. If one does not have sufficient systemic enzymes there are quality supplements that address that problem until the body can get back in balance and produce these enzymes in the quantity needed. Drugs are acidic and further weaken the body and encourage more pathogen growth. Its a free country and we can all do as we wish, but it is my belief all human disease and negative conditions are a result of an unhealthy PH balance. Address that balance, address the digestion that creates that balance and the body will rebound. parasites produce more acids so its a vicious cycle. Bentonite powder is by far the best way to eliminate acids from the organs. Its not an overnight process and can take up to a year or two. if I were you I would learn to write American and use the z in place of the s. If gives away your nationality as a Brit.
