The Borrelia burgdorferi bacteria causes Lyme disease, which is a bacterial infection. Infected black-legged ticks or deer ticks bite humans, causing them to get the disease. Ticks are little arachnids that prefer grassy or woodland areas to live. There are various natural treatment for lyme disease in humans. A few examples include vitamin B-1, vitamin C, fish oil, alpha lipoic acid, magnesium, chlorella, cat's claw, garlic, olive leaf, turmeric, and glutathione.
