Evidence Summary

A small placebo-controlled study (PMID: 26571987) found that 300 mg/day of ethanolic holy basil leaf extract improved specific cognitive parameters including reaction time and error rates on cognitive tests, with some reduction in P300 latency. A 1996 crossover trial (PMID: 8880292) reported significant reductions in fasting blood glucose (by ~17.6%) and postprandial blood glucose in patients with non-insulin-dependent diabetes mellitus. Holy basil was also included in a multi-herb adaptogen formula that reduced perceived stress, anxiety, and improved sleep quality compared to placebo (PMID: 41656269), though its individual contribution cannot be isolated from that combination study.
