The Changtang Plateau is the highest spot in the world, featuring a highly frigid climate and a scarcity of oxygen. The plants and animals that are able to survive there boast a high adaptability to their harsh environment. The Four-Volume Medical Code notes that everything in the world can be used as medicine, which holds especially true in this part of the world. Here, there are animals, plants and minerals that can all be adopted as medicinal materials. Major ones include the following
1.Rhodiola. Growing in the rocky places of snow-covered mountains, Rhodiola is of a cold nature and can be used to treat acute betrite diseases. It therefore has a curative effect on those who suffer from TB, spitting blood, poisoning and a scarcity of oxygen.
