Does Ophiopogon japonicus (Mai Dong) increase or decrease blood pressure?

Generally, Ophiopogon japonicus (MJ) may help lower blood pressure, and it is recommended to use MJ according to medical advice. Detailed analysis is as follows:

MJ contains various bioactive components, such as ophiopogonin and polysaccharides. These components have effects of vasodilation and improved blood circulation, thus helping to lower blood pressure. Additionally, MJ can enhance the activity of β-adrenergic receptors and inhibit the renin-angiotensin-aldosterone system, and these mechanisms also contribute to its blood pressure-lowering effects.

Individuals with hypertension or other cardiovascular diseases are advised to consult a qualified traditional Chinese medicine practitioner or physician before using MJ or any other herbal medicine to ensure safety and effectiveness. Moreover, MJ should not be used as the sole treatment method, but rather as part of a comprehensive treatment plan under medical supervision. During use, monitor your body's response closely, and seek timely medical advice and adjustments if any discomfort occurs.

In daily life, it is recommended to maintain healthy lifestyle habits, such as regular作息 (sleep-wake cycles) and avoiding excessive fatigue, which can help stabilize blood pressure levels.
