Catechins from tea reduce headaches
Effect of Catechins on Upper Respiratory Tract Infections in Winter: A Randomized, Placebo-Controlled, Double-Blinded Trial.
Significant headache improvement noted
We conducted a randomized, double-blinded, placebo-controlled trial to explore how consuming catechins from green tea affects symptoms like headaches during upper respiratory tract infections (URTIs). Our participants were healthy individuals who either received a bottled beverage containing 490 mg of catechins or a placebo without any catechins.
Impressively, we observed that those in the catechin group reported significantly reduced headache durations compared to the placebo group. Specifically, our findings showed a substantial improvement, highlighting the positive influence of catechins on not only headaches but also other URTI symptoms such as nasal congestion and running nose.
By integrating daily catechin consumption from bottled drinks, we discovered that these compounds can indeed help alleviate some discomforts associated with URTIs. Overall, this suggests that a simple addition to our diets, like enjoying green tea, could be beneficial in reducing the severity of headaches when dealing with winter colds.

Catechins may alleviate headaches
Effect of Catechins on Upper Respiratory Tract Infections in Winter: A Randomized, Placebo-Controlled, Double-Blinded Trial.
Study relevance: moderate.
We conducted a rigorous, double-blinded, placebo-controlled study to investigate the impact of catechins, particularly from green tea, on headaches during upper respiratory tract infections (URTIs) in winter. In our trial, healthy Japanese participants were divided into two groups: one received bottled beverages containing 490 mg of catechins, while the other received a placebo with no catechins.
The findings were promising. Participants in the catechin group experienced a significant reduction in headache duration compared to those in the placebo group. Specifically, our study revealed a notable decrease in the severity of headaches, alongside other symptoms such as running nose and nasal congestion. This suggests that consuming catechins may offer some relief.
While the study highlights the potential benefits of catechin consumption through bottled beverages, it is essential to note that the investigation doesn't isolate the effects solely on headaches. Therefore, we should view these results with an understanding that other variables might affect our conclusions regarding headache relief.

Green tea's role in migraine relief
Analgesic effect and mechanism of the three TCM-herbal drug-combination Tou Feng Yu pill on treatment of migraine.
Combination effects complicate assessment
We investigated how Tou Feng Yu pill (TFY), which includes green tea extract, influences migraine-related headaches. In our study, we observed that TFY significantly reduced pain responses in models of induced pain, indicating its potential effectiveness in alleviating headache symptoms.
Notably, TFY appeared to modify key biochemical markers associated with migraines. For example, we noticed decreases in plasma calcitonin gene-related peptide (CGRP) and serum nitric oxide, which are often linked to migraine episodes. At the same time, levels of certain neurotransmitters and vasoprotective factors improved, suggesting that TFY could play a role in managing migraine symptoms.
However, it's crucial to mention that while TFY shows promise in treating headaches, we did not specifically isolate the effect of green tea extract on its own within this study. Therefore, the exact contribution of green tea to the overall efficacy of TFY remains unclear. Overall, these findings point to the need for more detailed research to better understand how each component, including green tea, impacts headaches within this herbal combination.

Less frequent headaches
I suffered from terrible headaches three to four times weekly, but after taking melatonin consistently, they've significantly decreased to just two each month. Improved sleep quality seems to be the key.

Reduces morning headaches
I was waking up with headaches, about 30-40% of the time. After starting melatonin, my morning headaches have nearly disappeared, and I’m sleeping much better. I highly recommend this.

No more headaches
Some melatonin products left me feeling hungover with a splitting headache, but this cleaner brand helped me sleep without such issues the following day. I’m satisfied with its effects.
