Peppermint

Peppermint oil has an NNT of 3 for IBS abdominal pain relief, meaning one in three treated patients achieves clinically meaningful benefit. Peppermint's NNT of 3 for IBS compares favorably to statins, which require 50 patients treated for one to benefit in primary prevention. Peppermint has among the most statistically compelling evidence of any essential oil in clinical use. Using raw peppermint essential oil in a capsule preserves both the aromatic and gut-directed therapeutic effects, unlike enteric-coated commercial capsules alone.
