In Tibetan, "Lum" indicates the traditional knowledge and practices of bathing in natural hot springs, herbal water or steam to adjust the balance of mind and body, to ensure health and treat illnesses. Sowa Rigpa, the Tibetan name of the medicinal practice, literally meaning the knowledge of recuperating, was originated on the Qinghai-Tibet Plateau with an average altitude of 4,000 meters above the sea level. The traditional Tibetan medicine prescriptions of treating illness with herbs and minerals date back 2,500 years. (Xinhua/Purbu Zhaxi)
