Your skin is the biggest organ in your body, so it’s common sense to want to keep it healthy and practices to promote radiant skin span many centuries and cultures. Ayurveda, a system of holistic Indian medicine, identifies dryness as one of the main disease pathways and the primary contributor to aging and degeneration. Many conditions from chronic constipation to osteoarthritis and even neurological disorders are seen in Ayurveda to have their roots in chronic loss of lubrication throughout the physiology. Dryness is a natural side-effect of aging, but it can be accelerated or stymied through lifestyle choices.
