I've had some success with topical EOs. When I first started out my parasites weren't resistent, as they are now. When I applied EOs along with taking an internal cleanse, I could feel them move down into the colon and rectum positioning for elimination.

When you use EOs you want to get the best. I have found Oshadhi, Young Living or Primavera Life or Maharshi Ayr-Ved products most reliable and unadultered. Most other brands are junk, even though they claim they are pure.

Make sure that you use a small amount of oil with you EOs, so that you don't burn your skin. EOs are very concentrated and volatile oils.

If you do a Google search you will find lists on EOs for parasites. Good luck
