vasodilators
Blood passage openers
Vasodilators are substances or medications that widen blood vessels by relaxing the muscles in vessel walls.
This lowers blood pressure and improves blood flow.
Common vasodilators include nitroglycerin for chest pain and drugs for hypertension.
Alcohol and heat act as natural vasodilators: The wine made her cheeks flush as blood vessels dilated.
