Thai poultice massage is a technique that involves special poultices made of herbs and spices that are wrapped in muslin or cotton and steam-heated. Steam heating allows the natural essential oils and aromas of the herbs and spices to be released. During massage, the poultices provide moist and nutrient-rich relaxation to the skin and muscles. While offering comfort, the poultices also work with the body's natural energy to promote harmonization of the body's energy flow. They do this by loosening energy blockages and stimulating blood circulation.
