Moxibustion is a technique that boost immune function and energy levels. It improves digestion, slows down the progression of arthritis and can benefit skin disorders. Moxibustion utilizes an herb called artemisia vulgaris, a mossy substance, that is burned directly on the skin. The heat of the herb opens the pores of the skin and allows the oil from the herb to penetrate the skin, causing therapeutic effects. The patient will experience a warm to hot sensation and the oil leaves a yellow stain on the skin. This is traditionally a more Japanese acupuncture style, which Rachael is adept at practice.
