Chiropractic is not something new. With time it has become more specific and understandable. The basic idea of chiropractic is that a misalignment of the spine that allegedly interferes with nerve signals from the brain is the cause of most medical problems. By aligning the vertebrae and removing restrictions on the spinal nerves, chiropractic claims to allow the spinal cord to more effectively relay messages back and forth the brain, thus promoting better health. Meruchikitsa is an ayurvedic equivalent of chiropractic.
