Pharmaceutical use of Graptopetalum and related plants
View Patent ↗The present invention relates to compositions comprising Graptopetalum and uses thereof Graptopetalum can protect animals from liver diseases and medical conditions, such as inflammation, steatosis, and fibrosis. In particular, Graptopetalum inhibits proliferation of activated hepatic stellate cells, which play a pivotal role in liver fibrosis. Graptopetalum also has anti-fibrosis activities as well as inhibits proliferation of lung fibroblasts. Therefore, in addition to being a prophylactic and therapeutic agent for the liver, Graptopetalum is useful against fibrosis or inflammation of tissues or organs other than the liver, in particular lung, kidney, and bladder. Other plants in the family of Crassulaceae, particularly Echeveria, have similar effects as Graptopetalum.
1. A method of treating a subject suffering from or susceptible to a liver disease or medical condition, comprising administering an effective amount of a pharmaceutical composition that comprises an ethanolic Graptopetalum extract to the subject, wherein the liver disease or medical condition is selected from the group consisting of liver inflammation, liver steatosis, liver fibrosis, liver cirrhosis, and hepatitis B.
2. The method of claim 1 wherein the ethanolic Graptopetalum extract is obtained from Graptopetalum paraguayense.
3. The method of claim 1 wherein the liver disease or medical condition is liver inflammation.
4. The method of claim 1 wherein the liver disease or medical condition is liver fibrosis.
5. The method of claim 1 wherein the liver disease or medical condition is liver cirrhosis.
6. The method of claim 1 wherein the liver disease or medical condition is hepatitis B.
7. The method of claim 1 wherein the liver disease or medical condition is liver steatosis.
8. The method of claim 1 wherein the pharmaceutical composition is administered orally.
9. A method of treating a subject suffering from or susceptible to a liver fibrosis, comprising administering to the subject an effective amount of a pharmaceutical composition that comprises a Graptopetalum extract.
10. The method of claim 9 , wherein Graptopetalum extract is obtained by extracting the whole Graptopetalum with ethanol, acetone, chloroform, or methanol.
