Mom, I have NO idea about "overdosing" on cloves, wormwood and blackwalnut hull, but I do know that over the long haul, MHs dewormer WORKS. I've passed all kinds of uglies!!!! I did my original parasite cleanse just a little over a year ago and have been on maintenance with it since then.
We live in an ocean of parasites. They are here to rid the planet of the curse of mankind. They are also here to rid our body of toxic wastes. If you don't feed them, they die. If you cleanse your body of toxins, they die.
There are foods that kill parasites ... pineapple, I eat at least one raw one a week as a meal ... pumpkin seeds are parasitic ... oregano oil ... olive leaf ... coconut oil and coconut.
If you do a month long parasite cleanse on Dewormer and still fill there is a problem, MH recommends Hulda Clark's Mop-up program.
