Parasites may die and decay within the body or be flushed out. If they die in the body, infection from the decay is a possibility. So, for the next two weeks, I suggest an immune boosting protocol. Then, I think one more week of the anti-parasitic herbs is usually a safe measure. Afterwards, there is still the need to heal.
Parasites sometimes perforate organs.
They also tear up membrane linings in the intestines, they suck blood, they deposit excrement in the body that puts off an ammonia gas, and so on and so forth. I believe it is important to use rejuvenative tonic herbs once completing the parasite protocol. I usually suggest that people think of devoting a year and a half to liver regeneration. Some people also need heart herbs or kidney herbs or colon herbs. It is extremely difficult to find proper supervision for this kind of program.
