Common Names: King of Herbs, Edaxia, Locoweed
Scientific Names: Oxytropis falcate
Oxytropis falcate, commonly known as 'edaxia' or the 'King of Herbs' in Tibetan medicine, is a wild Leguminosae plant native to the Qinghai-Tibet plateau, China, thriving at elevations between 2700 and 4300 meters. Despite its long history of traditional use in treating various ailments like inflammation, influenza, pain, bleeding, and anthrax, edaxia remains significantly under-researched. Preliminary studies suggest potential potent painkilling effects attributed to its content of phenethylamines. While the plant's composition is somewhat characterized, there is limited research, with a single rat study exploring topical pain-killing and anti-inflammatory effects. Some sources indicate that dried and processed oxytropis falcate is used as a health supplement, containing compounds like beta-sitosterol and pinocembrin, believed to lower cholesterol, reduce swelling, and aid concentration. However, caution is advised due to its poisonous nature in raw plant form, and despite its use in traditional Chinese medicine, there is limited understanding of its benefits and potential side effects. Individuals considering oxytropis falcate supplements should consult healthcare professionals to ensure safety and determine appropriate usage.
