I had to do a parasite cleanse for pinworms when I was a kid. Blech! Never want to go thru that again. Never ever ever! LOL!
Clarkia is another prepared parasite cleanse that people use. Either Clarkia or Paragone should do ya' just fine. :)
As a quick test to see if you have any, you can overdose on turmeric. Turmeric is very purifying to the entire digestive system and blood, and quite irritating to any little monsters you may have picked up in asia. TAke about 1,000 mg 3x a day for 7 days while doing colon cleansing and inspecting what comes out.
