Study Finds Peppermint Tea Improves Memory, Attention in Healthy Adults

 A randomized placebo-controlled clinical trial found that a single cup of peppermint tea produced measurable improvements in memory and attention in healthy adults, according to a study published in May 2025 in the journal Human Psychopharmacology. Researchers at Northumbria University in the United Kingdom observed that drinking 200 milliliters of brewed peppermint tea led to better scores on cognitive tests compared to a placebo group.

The study also recorded increased oxygenated blood flow to the brain's prefrontal cortex, the region responsible for focus and decision-making, within a short window after consumption.

Neither the cognitive improvement nor the increased cerebral blood flow was observed in the placebo group, the study stated. Researchers noted that the effects appeared to operate independently of each other, suggesting peppermint may influence brain function through multiple biological pathways simultaneously. The findings indicate that a standard mug of peppermint tea is sufficient to produce these acute effects on brain performance and physiology....<<<Read More>>>...
