When I said less exsposier I was refering to parasites from animal products. parasites are a natural part of life.You can get roundworms from walking barefoot over soil.There are lots of good books on the subject.You can also contact a naturopathic practitioner for advise on your parasite issue.Garlic oil can be purchased at most healthfood stores.Dr. Hulda Clark has claimed intestinal flukes cause"all diseases"I hope he is wrong!It might take a while to kill theme off do to the length of there life cycle.Good luck!!
