Vasospasm: When there is vasospasm of the arteries in the brain, an intraarterial infusion of verapamil or balloon angioplasty of the major vessels can help to overcome the arterial narrowing too. Maintaining high cardiac output, elevated blood volume, and relatively dilute blood concentration (hematocrit 30) can reduce the risk of stroke due to vasospasm. ...Read more
Blood vessels have the capability of increasing or decreasing their diameter. When a blood vessel dilates, it generally leads to lowered blood pressure. Drugs that cause this are termed vasodilators. These can act on arteries or veins. Some classes of vasodilators include nitrates, calcium channel ...Read more
Unknown: The national institutes of health center for complementary and alternative medicine has no listing for burdock. Webmd does but doesn't comment on mechanism. Be aware that some formulations of burdock contain belladonna which is poisonous if overdosed. Unlikely that the mechanism of burdock has ever been systemically studied as no one would pay for it. This is the problem with all otc herbs. ...Read more
Sure.: But, for what purpose? Nitrates (for example found in beetroot juice) & folic acid can possibly lower blood pressure at least in part via vasodilation.

If we know what you want to do, we can probably answer better. ...Read more

Caffeine is...: Caffeine has a near-identical chemical structure as theophylline, a well known bronchodilator. As for the vasculature, caffeine typically vasoconstricts the peripheral vasculature as reflected in increased systolic & diastolic pressure, but not cardiac output or left ventricular contractility. Caffeine also blocks (inhibits) Adenosine in the brain--this is what keeps you awake... ...Read more

Depends: I am not sure if you're looking for a medication that would cause either of these. I wouldn't recommend anything like that. But simply heat or cold cause vasodilation and vasoconstriction respectively. Early on, cooling an extremity injury helps with decreasing inflammation. Later (24 to 48 hrs), heating may help in promoting circulation. ...Read more

Maintaining appropriate levels of Nitric Oxide is extremely important to our overall health. ...Read more

No vasodilator: Vascular headaches result from vasodilation. Medications used to treat migraine headaches constrict blood vessels or block (beta) adrenergic (vasodilating) substances. Alternative medicine approaches include the use of omega 3 fish oil, feverfew, co-enzyme q10 and melatonin. Massage therapy, aromatherapy, acupuncture and acupressure have also been used. Feverfew has scientific support. ...Read more
Alcohol is a vasodilator and midodrine vasoconstrictor, if you took both which would win and how do you know?
If verapamil is a vasodilator how can it be a headache medicine when vasodilation caused headaches?
If a vasodilator dramatically improves my vision dexterity mental clarity & more, does that mean something keeps my brain from gettingenough blood/O2?
Think this way: Like stepping on a garden hose cuts down the amount of water coming out of the hose, a vasodilator would remove your foot from the hose allowing more water to flow.
