This is the lamp hand mined in the Himalayan mountains that utilizes halotherapy to help treat respiratory ailments. Made from a large, solid crystal of genuine Himalayan salt, the lamp employs the millennia old natural remedy first introduced by Hippocrates in ancient Greece. An included 15-watt bulb gently heats the salt, which releases charged particles that help allergy and asthma sufferers clear their airways. Unlike remedies using processed chemicals, crystallized Himalayan salt contains over 80 essential minerals such as sulfate, magnesium, calcium, and potassium. The salt maintains its efficacy for five years and its pink/orange color varies naturally. The lamp’s 5 1/2" diameter base is made with rich-hued 1 1/2"-thick rosewood. Due to the hand-made nature of this item, each is unique and weighs 27-35 lbs. Plugs into AC with 6' cord. 13" H x 7 1/2" W x 5" D.
