What are the scientifically proven benefits of mint?
Quick answer
Mint (Mentha piperita) has clinical-trial evidence for IBS symptom relief, post-surgical nausea reduction, and antimicrobial activity. Peppermint oil is recognised in published gastroenterology guidelines. Fresh mint in juice is milder than oil but contributes the same active compounds — menthol and rosmarinic acid.
Mint is one of the most well-studied herbs in the world. Clinical evidence is particularly strong for digestive benefits — a meta-analysis found peppermint oil significantly superior to placebo for relieving IBS symptoms and abdominal pain. Mint also demonstrates significant antimicrobial activity against both Gram-positive and Gram-negative bacteria, strong antioxidant capacity, and antiviral properties.
