Blood-Full Grass, called "Yugu Xingnabu" in Tibet, is mainly distributed in Yunnan, Ningxia, Tibet, Qinghai, Guizhou, Gansu, Shaanxi, and other regions in China. In Tibetan medicine, it is directly referred to as "jiegu wood," and it has the effects of dispelling wind, promoting diuresis, invigorating blood circulation, and promoting meridian flow.
【Research Objective】
To study the anti-inflammatory and analgesic effects of water and alcohol extracts of blood-full grass, a traditional medicine used by the Yi people in Yunnan.
【Research Methods】
The safety of the two extracts of blood-full grass was evaluated using the maximum dosage. The anti-inflammatory and analgesic effects were studied through experiments using the xylene-induced mouse ear swelling method, the acetic acid-induced mouse writhing method, and the hot plate-induced mouse foot pain method.
【Research Results】
Both extracts of blood-full grass significantly inhibited xylene-induced mouse ear swelling. They also showed significant antagonistic effects against acetic acid-induced mouse writhing. In the hot plate test, blood-full grass significantly prolonged the licking time of the mouse's foot.
【Research Conclusion】
Administration of water and alcohol extracts of blood-full grass to mice (at doses 630 times and 600 times the clinical human dosage, respectively) did not cause obvious toxicity. Both extracts of blood-full grass exhibited good anti-inflammatory and analgesic effects.
【Traditional Chinese Medicine Application】
In traditional Chinese medicine, blood-full grass is used not only in Han medicine and Tibetan medicine but also by the Hani people to treat fractures and sprains.
The Tujia people use it to treat bruises, sprains, fractures, and swelling.
The Buyi people also have their own folk recipes, using the stems and branches of blood-full grass to treat rheumatic joint pain, bruises, fractures, and bleeding from wounds.
