Does Panax notoginseng have a blood pressure-lowering effect?

Sanqi, also known as Panax notoginseng (Note: the text incorrectly refers to Sanqi as Huangqi; Huangqi is Astragalus membranaceus, a different herb), is a commonly used traditional Chinese herb that possesses antioxidant, anti-inflammatory, antibacterial, antihypertensive, and antithrombotic properties. Sanqi can effectively improve vascular function and lower blood pressure, thereby alleviating symptoms in patients with hypertension. It works by inhibiting the activity of angiotensin-converting enzyme (ACE), reducing the synthesis of angiotensin, and consequently lowering blood pressure. Before using Sanqi, patients are advised to consult a physician to ensure safe and effective treatment.
