Dry brushing, also known as garshana, is an Ayurvedic technique that promotes lymphatic health. It is essential to maintain lymphatic health as it filters toxins, viruses, and bacteria. The skin is our largest organ and is one of the drainage pathways via sweat. It drains fluid from the tissues of the body. Unlike the cardiovascular system, which has a heart that pumps blood throughout the body, the lymph moves primarily with exercise, breathwork, and massage.
