This is Dr.Bailey, naturopathic doctor and oldest daughter of RG. Daddy retired a while back and I am now the president of Humworm. I will try to answer your quesstions.
1. Humaworm has helped many people who suffer from Irritable Bowel Symdrome. Parasites put off toxins which affect the liver. This causes the liver to concentrate on removing toxins instead of naking the 1-1 1/2 quarts of bile needed every day for good digestion. This can cause both chronic constipation, chronic diarrhea or a combination of both.
2. The Kidney cleanse will help dissole the stones. It is taken after the Humaworm parasite cleanse.
3. Oxypowder is fine, it is the same as epsom salts which are magnesium based. Either can be taken along with Humaworm. As noted in #1, when the liver is too busy removing toxins, it does not make enough bile. This is why some people will get a tad constipated during a parasite cleanse.
