Everywhere you research online about boosting your immune system it typically goes over the same stuff. Tumeric garlic vitamin C vitamin D, etc. I wonder if there is anything that is not heard of as much that is an extreme immune booster. I remember reading about some fruit called soursop that cures cancer but on the other hand It can also be toxic. I'm wondering if anyone knows of anything that the public or you won't find on Google that is an extreme immune booster beyond all the mainstream talks about?
