The thing about parasite, is you have to keep the body saturated for a extended length of time, you cannot really do that with Ivermectin and DMSO because it is too dangerous to toxic. Ivermectin is a great product, but in my opinion it is more of a One-Shot kill. It is not designed to take on a regular basis, in my opinion you need to decide what natural dewormer that you can take on a daily basis for a extended length of time, I remember when I got started 20 years ago one of the first things that I used was olive leaf, it literally started driving parasites out of my chin and was creating water blisters. So olive leaf in my opinion really gets overlooked. But in my opinion I would Target the liver because that's where the mixture goes in. If you really want to see some parasites coming out of your liver, what I have done was during a liver Purge, I would drop one gel cap of all of oregano essential oil. That means pure oil not diluted in a empty gel cap. I believe if you bring me any human, within one or two days I will have them expelling all kinds of creatures out of their body, especially the liver flukes.
