Introduction

In general, boiling litchi shells in water may help lower blood pressure as an adjunct, but it cannot replace standard medical treatment. When using litchi shell water to assist in regulating blood pressure, ensure the litchi shells are thoroughly cleaned to avoid impurities affecting health. Consumption should be moderate each time, avoiding excessive intake that could burden the body. Patients with hypertension should still strictly follow medical advice and take antihypertensive medications on schedule.

Generally, boiling litchi shells in water may assist in lowering blood pressure, but it cannot replace standard medical treatment. Detailed analysis is as follows:

Litchi shells contain certain natural plant components that may mildly affect blood vessels—for instance, potentially helping to dilate blood vessels and improve blood circulation, thereby exerting a slight auxiliary regulatory effect on blood pressure. Additionally, drinking water boiled with litchi shells increases fluid intake, which helps promote the excretion of sodium from the body, offering some benefit in maintaining stable blood pressure. Therefore, it can provide some auxiliary support in lowering blood pressure. However, the effectiveness of litchi shell water in lowering blood pressure is very limited and cannot achieve the results of pharmaceutical treatments. Hypertension is a complex chronic disease whose development is related to multiple factors such as heredity, environment, and lifestyle. It requires comprehensive management through standardized medication, dietary adjustments, regular exercise, and other integrated approaches.

When using litchi shell water to help regulate blood pressure, ensure the shells are thoroughly cleaned to avoid harmful impurities. Consumption should be moderate—excessive intake may burden the body. Patients with hypertension must strictly follow medical advice, take antihypertensive medications regularly, and monitor blood pressure changes periodically. If discomfort or abnormal blood pressure fluctuations occur after consumption, seek medical attention promptly.
