Can onions lower blood pressure?

onions do not lower blood pressure.

Food has no therapeutic effect, so onions do not lower blood pressure levels. High blood pressure means that the lateral pressure of blood on the blood vessel wall is higher than normal, and the substances contained in onions do not dilate blood vessels or reduce blood volume, so they do not play a role in lowering blood pressure. Patients with high blood pressure should strictly follow the doctor's advice to use nifedipine, metoprolol, enalapril and other drugs.

Patients with high blood pressure should develop healthy daily life and eating habits to help control blood pressure levels.
