The heat therapy used in the clinic consists of two different types. One type used is a TDP lamp. The TDP lamp or TDP mineral lamp is a far infrared light which increases the circulation of an area and loosens the muscles and tendons so the body may be able to heal the area of concern. The other type of heat therapy is called moxibustion. Moxibustion is the use of an herbal stick to perform the same function as the TDP lamp. The herb is incorporated into a charcoal stick so that it stays lit for use where warmth, dryness, and increased circulation of an area is needed.
