If you are in a car accident or get shot, stabbed or some other injury doctors are great, but for disease they are worthless and useless. You can knock out IBS with aloe vera. No drugs, no ignorant doctors just good cheap natural healing with a free and healthy plant. I can but the leaves in the grocery store where I live for a dollar and a half per leaf. I also have many plants growing in my yard for free. I drink one large leaf every day mixed with coconut water and flax seed.
