This variation of traditional Thai Massage that for centuries was used only in the Royal Thai Palaces uses only hand, thumbs and body weight balance to deliver the service. It is based on the principles of acupressure and involves working on the body's energy lines to release blocks that are said to cause discomfort and disease. Specially prepared warm herbal compresses, Luk Pra Kob, are also applied to help draw out toxins and promote circulation.
