Are there scientific studies that prove the medical effectiveness of Rheum palmatum?

Yes, there are several scientific studies that prove the medicianl effectiveness of Rheum palmatum. Here are some studies that are worthy of notice.

According to a study published by "Advances in experimental medicine and biology", Rheum palmatum has been found to have several medicinal effects, including the treatment of lung, liver, kidney, womb, and bladder diseases, as well as cancer and diabetes. Additionally, Rheum palmatum has been shown to be effective in alleviating conditions such as diarrhea and constipation. Its therapeutic properties have also led to the development of various pharmaceutical formulations containing its extract.

In another study published by "Zhongguo Zhong xi yi jie he za zhi Zhongguo Zhongxiyi jiehe zazhi = Chinese journal of integrated traditional and Western medicine", the extract of Rheum palmatum was found to have beneficial effects on patients undergoing hemodialysis, including significant increases in serum levels of albumin, pro-albumin, fibrinectin, and HDL-c, as well as apolipoproteins A1. Additionally, it was observed that treated patients experienced a decrease in serum levels of TC, LDL-c, apo B, and apo B/apo A1. These findings suggest that Rheum palmatum extract may play a crucial role in improving lipid profiles and albumin levels in hemodialytic patients.

A different research published by "Zhongguo Zhong xi yi jie he za zhi Zhongguo Zhongxiyi jiehe zazhi = Chinese journal of integrated traditional and Western medicine", Rheum palmatum has been found to improve renal function by inhibiting the production of IL-6. This results in a reduction of immune inflammation, which is beneficial for chronic renal failure patients. Additionally, treatment with Rheum palmatum led to a significant decrease in serum creatinine levels, indicating an improvement in renal function.
