I think the best shot as far as frequency controlled electronics is a doug coil machine. I am trying to get feedback on a different forum. For me personally I feel like I have just about tried every avenue with medication and herbs. It still doesn't mean I don't take them, I do. But there has to be something more I can add to get rid of them. But, I think a doug coil machine is more appropriate that using a rife machine per say for the larger more cumbersome parasites.
Maybe you could luck out and someone might rent you one. Or maybe a chiropractic office might have one. I don't know.
