Headaches: Can green tea provide relief?

Green tea is derived from the same plant specifically Camellia sinensis as black tea, but it is cured in a different manner. This tea is common in Japan and China as well as in other countries as well.

Green tea is often suggested as a healthy beverage and considered as a natural measure for various conditions such as those who have high level of cholesterol. The tea might also beneficial in managing certain kinds of headaches including migraines. Sadly, green tea is also a potential trigger for headaches in some individuals.

Connection between green tea and caffeine

The main active ingredient in green tea that both relieves and triggers headaches is caffeine. Always bear in mind that green tea includes a moderate dosage of caffeine, usually 8-36 mg of caffeine in a 5 oz. cup. This is relatively lower than the caffeine present in a 5 oz. of black tea which contains between 25-110 mg.


Even though green tea can be effective in alleviating headaches in some individuals, it might actually be a trigger in some cases.

Link between caffeine and analgesics

Caffeine is often combined with analgesics such as acetaminophen and aspirin since it helps increase the effectiveness. A dosage of caffeine can help make the pain medications a lot more effective.

With this in mind, an individual is allowed to use less medication per dosage, thus reducing the risk for side effects, rebound symptoms as well as addiction. Caffeine also helps with the absorption of the medication at a rapid rate which allows the individual to achieve relief sooner.

The addition of caffeine and using less medication reduces the risk of the individual for potential side effects as well as minimizing the risk for habitual or addictive use. The quantity of caffeine present in a 5 oz. cup of green tea is similar to the commercial over-the-counter brands of the aspirin variants that include caffeine.

What is vasoconstriction?

Another method in which the caffeine in the tea alleviates headaches is via vasoconstriction. Right before the onset of the migraine, the blood vessels in the head start to dilate. Caffeine can cause the blood vessels to constrict. A cup of green tea along with its moderate dosage of caffeine can stop a headache.

Can green tea cause headaches?

Even though green tea can be effective in alleviating headaches in some individuals, it might actually be a trigger in some cases. The caffeine can sometimes trigger migraines directly. More often, the headaches manifest due to withdrawal to caffeine once an individual ceases the consumption of caffeine after an extended period of regular usage. Due to this, it is recommended to avoid daily intake of caffeine by those who suffer from frequent headaches.
