You might look at Dr. Lee Meritt's site, Medical Rebel. She believes virtually all diseases are caused by parasites and thinks highly of Ivermectin. It has a long history of being used safely. As a nurse assistant, I observe that those who use alternative treatments fair better than those who use only pharmaceuticals. God Speed His blessings to your father.
I took the leap and am so pleased. I really love my church and am learning so much more about Christianity and the Bible than I did as a Protestant. These ancient liturgies allow me to sink deeply into myself where I feel close to God. I trult feel myself becoming a better person. Why not give it a try?
It is hard to stand up to the medical system but it will help to find resources for natural health such as Green Med, Dr. Lee Merritt, homeopathic medicine. Move away from fear of allopathic medicine to a joy in being healthful and self-sufficient. The two of you are doing a great job; proud of you.
