The evidence, graded

expert consensusUS safety reviewers (2026) judged 6 sage ingredients made from the leaf or the oil, sage leaf extract among them, safe as used in products made not to cause allergy. They were concerned that some compounds in sage, called terpenes, could cause allergy, and told makers to avoid harmful levels. A product with 0.005% leaf extract, diluted for the test, didn’t irritate or cause allergy in a repeat patch test on 53 people. For 6 other sage ingredients they had too little data to judge.Raj 2026 · International Journal of Toxicology ↗
