Sennenkyu Taiyo 24 Self-Heating Moxa Plaster

A self-adhesive moxibustion plaster that eliminates the need for external heat sources. Heat is generated through the oxidation of refined, powdered iron. This heat in turn vaporizes a proprietary moxa formula that permeates the skin's pores providing the benefits of moxa therapy. The 0.25" x 1.3" dia plaster produces an average temperature of 40°C (104°F) warmth for approximately 30 minutes.
