"Things that can go wrong..." Disease is viewed in Tibetan medicine as an imbalance of the three humors - but the exact word in Sanskrit as in Tibetan is literally "things that can go wrong." The three major elements of the body are called wind, bile and phlegm.
Wind is sometimes translated as neural energy. There are winds that relate to the upper body: which enters the upper body,as when we swallow, speak, etc. Other winds relate to the lower body: energy in and out down the body, as in the case of detention or release excretions, menstruation and orgasm. And yet other winds relate to blood pressure, motor skills, as well as different types of energy in relation to the heart.
Bile handles certain aspects of the digestion and assimilation, such as liver bile. It also relates to various aspects of pigmentation, as when we catch a sunburn, as well as hemoglobin, red blood cells and health related to vision.
Phlegm concerns systems mucos and lymph in the body. It relates to colds, sinus problems and to sinovial fluid in the joints. For example, rheumatism and arthritis are phlegm disorders.
A Tibetan doctor examines the relationship between these three elements by taking your pulse, discussing your symptoms, and looking for external signs of imbalance or illness.
