My Dr. who is an MD, but uses Eastern medicine believes a large part of the population in the US have parasites and that even if infected and tested, they are not normally found. He uses natural medicine if possible, but experience has shown pharmaceuticals must be used to initially remove them, after that a regular regimen of natural products can be used. I am currently on 4 medications for parasites 2x day for 45 days, including Ivermectin. He also included an anti-fungal and homeopathic drops. His experience is that ridding the body of Parasites cures many types of illnesses, including some cancers. After 4 weeks, I am already feeling better. He took hair samples, performed a test for heavy metal toxicity, etc. I will find out more at next appt. There are so many simple cures they are keeping from us. He was trained in the military and worked in third world countries. At times he only had 2 medicines to prescribe guess what they were? Parasite medications. He found that these medications were curing a very wide range of illnesses. Now since in practice for many years in the US, he has found the same. I recommend everyone find a way to rid these from your body.
