MS is a chronic, progressive, degenerative disorder that affects nerve fibers in the brain and spinal cord characterized by intermittent damage to myelin – a fatty substance that surrounds and insulates nerve fibers and facilitates the conduction of nerve impulse transmissions – caused by the destruction of specialized cells (oligodendrocytes) that form the substance. Demyelination causes scarring and hardening (sclerosis) of nerve fibers usually in the spinal cord, brain stem, and optic nerves, which slows nerve impulses and results in weakness, numbness, pain, and vision loss. Because different nerves are affected at different times, MS symptoms often worsen (exacerbate), improve, and develop in different areas of the body. Early symptoms of the disorder may include vision changes (e.g., blurred vision, blind spots) and muscle weakness. In Ayurveda MS is treated with Langhana therapies to remove ama and dosha accumulation. If possible Ayurveda suggests using strong purifying methods (Shodhana) such as Pancha Karma to remove the dosha + ama deposits in the body. If this is not possible then Shamhana therapies can be used with the person over a long period of time. Shamhana therapies are preferable when the patient is too young, too old, too weak, too debilitated. Proper diet and regimen are also advised in addition to the prescription of nerve tonics, to restore the function of the nervous system.
