I do not recommend DE for internal use as it is designed to microscopically slice the hard exterior of bugs such as fleas and ticks. It is rendered useless when wet, therefore it does not do anything helpful for parasite removal when injested. I have had customers in the past who have totally stopped their colons up by using DE.
The best parasite cleanse is one in which the entire body is cleansed at the same time...the organs, the blood, the joints, the muscles, etc. Humaworm is excellent for this purpose.
The natural chemicals in the herbs need to pass through the liver and into the bloodstream. Using an enema with the herbs will not give the same effect.
