Sa-Wan Herbal Ball / 2 Pack / 50 Grams. The herbal ball treatment is traditionally a hot treatment. The Sa-Wan Ball is soaked for five minutes, and then steamed in a steamer for 10-20 minutes before use. It is pressed along the Sen Sib lines, or acupressure zones of the body in a series of motions that include: a pressing with steady downward pressure: a "rock 'n roll," or back and forth motion: a "rolling" or orbital circular motion: and a " dragging" motion which is used to increase blood flow and lymphatic drainage. The Sa-Wan ball is used in combination with traditional Thai or Swedish massage or as a tool to work on specific parts of the body that need special attention for muscular tightness or pain. Some of the herbs in the Sa-Wan ball include Lemongrass, Tumeric, prai, Kaffier Lime, Camphor, and Tamarind. Available in small 2 pack - 50 gram (facial) and large 2 pack - 150 gram (body) sizes.
