Biological Activities
Sonchus asper has demonstrated significant antihypertensive activity through recent investigations into its aqueous-methanolic extract. When administered to hypertensive rats, the plant extract effectively decreased both blood pressure and heart rate in a dose-dependent manner. Specifically, higher doses of the extract were found to be most effective at preventing the rise in blood pressure caused by glucose and egg-fed diets. Furthermore, toxicity studies indicate that the extract is safe, showing no significant negative alterations in blood chemistry at tested levels. These findings provide strong scientific evidence that supports the traditional medicinal use of this plant in managing hypertension.

Conditions
Preparations
Sonchus asper is prepared as an aqueous-methanolic extract derived from its aerial parts for scientific evaluation. This specific preparation was tested at doses of 250, 500, and 1000 mg/kg to determine its biological effects. The study revealed that the aqueous-methanolic extract significantly decreases blood pressure and heart rate in a dose-dependent manner. In particular, the 1000 mg/kg dose of this extract produced the maximum antihypertensive effect observed in the rats. Ultimately, the aqueous-methanolic extract of Sonchus asper demonstrated considerable antihypertensive activity, supporting its traditional medicinal use.
