LaStone Therapy is not your typical “hot stone massage”. It is a trademarked style of massage, founded by Mary Nelson of Tucson, AZ. LaStone Therapy uses both hot and cold stones (when needed) to massage the body. The use of cold stones may not sound very appealing, however, they have a very therapeutic effect when used in conjunction with the hot stones. Alternating between heat and cold both stimulates and relaxes the circulatory system, which is very detoxifying for the body. In cooperation with heated stones, chilled marble stones create a dramatic movement of fluids within the body. The combination of cold and heat creates a “flushing out” action of the toxins.
