After meals or at first sign of discomfort
“Peppermint oil capsules are licensed as a pharmaceutical treatment for IBS in several countries. The same active compound — menthol — relaxes gut smooth muscle in the tea. This is not folk medicine. This is established gastroenterology.”
How peppermint relaxes the gut — the smooth muscle mechanism
Menthol, the primary active compound in peppermint, activates calcium channels in the smooth muscle of the gut wall, causing relaxation. This reduces the spasms and cramping associated with irritable bowel syndrome. A 2014 meta-analysis of 9 clinical trials found peppermint oil significantly superior to placebo for global IBS symptom relief. Peppermint tea has lower menthol concentration than capsules, but consistent daily consumption provides meaningful digestive support.
Liquorice root: the most underrated digestive herb
Glycyrrhiza glabra (liquorice root) contains glycyrrhizin, which has demonstrated anti-inflammatory activity in the gastrointestinal tract. A 2012 trial in the journal Phytotherapy Research found DGL (deglycyrrhizinated liquorice) significantly reduced symptoms of non-ulcer dyspepsia. For throat health, liquorice root's demulcent properties coat inflamed mucous membranes — providing the soothing effect used in traditional medicine systems from Ancient Egypt to Ayurveda.
Hercules: the protector's formula
Hercules was the divine protector of mankind — tested, reliable, unbeaten. Mint and liquorice have been the digestive pharmacist's go-to combination for over three millennia because nothing has yet improved on them. Drink it after meals, after a rich dinner, when travelling, or at the first sign of a sore throat. The dosing is simple: one cup, brewed properly, as needed. This is the most straightforwardly useful blend in the MyLifeTea range.
