Aspirin’s Proven Benefit When arteries are already narrowed by the buildup of plaque, a clot can block a blood vessel and stop the flow of blood to the brain or heart.

Taking a regular dose of aspirin diminishes the ability of your blood to clump together into clots by targeting the body’s smallest blood cells..

A mild and transitory vasoconstrictor effect exists, which depends mainly on the caffeine concentration in the VSMC. However, the main and predominant effect of caffeine on the vascular wall is vasodilating, acting equally on the VSMC directly or indirectly and also on the endothelial structure.

Does caffeine restrict blood flow to brain?

This is likely the cause of the throbbing, pulsing pain most people experience during migraine.

Does alcohol constrict or dilate blood vessels?

At intoxicating levels, alcohol is a vasodilator (it causes blood vessels to relax and widen), but at even higher levels, it becomes a vasoconstrictor, shrinking the vessels and increasing blood pressure, exacerbating such conditions as migraine headaches and frostbite.

Is aspirin a vasodilator?
