Himalayan Salt Lamps make an attractive feature in any living space. Salt Lamps can enhance the quality of the air at your home and reduce asthma and hypersensitivity very quickly and also naturally. Himalayan Salt Lamps are actually solid blocks of Himalayan Salt that have been hand-carved. Deep underground mines in Khewra, Pakistan, are the only source of true Himalayan Pink Salt. Within the hollowed-out center of this block of salt is a light bulb followed by power cord that emits both light and heat.
