You just need some basic corrections.
First you need to get rid of candida which causes the intestinal problems and sinus problems. It is way way ore common than parasites. (thanks to Hulda Clark for her misguiding info). Get the Candida Zapper by BioElectric which will truly kill it, not just chase it from one place to another like all the cheap candida cleanses do.
Second you need to cleanse your gall bladder, liver, and kidneys since they are your body cleansers.
Gall bladder cleanse- drink 1/4 cup olive oil mixed with a citrus drink before going to bed and then lie on your right side in bed.
Liver- fasting is best but most people are too flacid to do so and there is Silymarin 50mg which is a good cleanser.
Kidneys- Stone Breaker (take two eyedroppers full every morning)
