Dr. Liu Aifen
Long-term use of Apocynum venetum leaf by patients with hypertension may lead to toxicity, such as nausea, vomiting, abdominal distension, and diarrhea. Apocynum venetum leaf helps clear liver fire and possesses heat-clearing and diuretic properties, thereby lowering blood pressure; however, it should not be taken long-term. Additionally, intake of greasy and high-calorie foods must be reduced to prevent a subsequent rise in blood pressure.
