Efficacy and Effects of the Traditional Chinese Medicine Alisma Rhizome

Alisma (Alisma orientale) is a commonly used traditional Chinese medicinal herb, yet many people in daily life may be unfamiliar with it—even unaware of its name. In fact, Alisma possesses numerous therapeutic effects and clinical applications. So, what are the pharmacological effects and therapeutic uses of Alisma?

Pharmacological Effects and Therapeutic Uses of Alisma

Alisma is native to Northeast China and is an aquatic plant. While the entire plant is toxic, it exhibits multiple medicinal properties. Alisma demonstrates anti-atherosclerotic, diuretic, and antihypertensive effects. It also possesses antibacterial and anti-inflammatory properties, making it useful for treating infections caused by certain pathogenic microorganisms.

Alisma helps prevent atherosclerosis. It reduces hepatic fat content and effectively inhibits fat accumulation in the liver, thereby preventing vascular atherosclerosis and suppressing the formation of intimal plaques in blood vessels—ultimately helping to prevent arterial hardening. It also exerts a pronounced diuretic effect. After ingestion, Alisma increases urine output while decreasing blood urea nitrogen and chloride levels. Its diuretic action is especially notable in patients with nephritis.

        Alisma also exhibits antihypertensive effects. Its ethanol extract induces gradual arterial constriction, promotes vascular relaxation, increases blood flow in the major coronary arteries, reduces ventricular pressure, and consequently lowers blood pressure. Moreover, Alisma may serve as an adjunctive agent in cardiac surgery. Additionally, Alisma possesses antibacterial and anti-inflammatory properties; for instance, it can be used to treat contact dermatitis. We hope this information proves helpful to you!
