While you may know it as the flavour of choice to remedy bad breath, peppermint was actually traditionally used in Herbal Medicine to aid digestion and help relieve stomach pain caused by gas.

While this aromatic herb can be steeped as a tea, cooked into anything sweet or savoury, or added as a dainty garnish to your favourite dish, our Bye Bye Bloating ensures you get all the benefits of a therapeutic dose.  Additionally, because we use the whole leaf form capsule rather than the oil, our product ensures you get all the added synergistic benefits of those leafy greens.

Additional research is studying the effects of peppermint on irritable bowel syndrome (IBS).

This research investigates the in vitro influence of 14 different edible plants, including peppermint, on the activities of digestive enzymes. It was found that peppermint had the second highest stimulation effect of all spices on digestive enzyme activity. The study concludes that the in vitro influence of peppermint has “a beneficial stimulatory effect on digestion through stimulation of lipase.”

Irritable Bowel Syndrome (IBS)

The researchers in this study conducted randomized placebo trials to assess the efficacy of peppermint oil capsules for the treatment of active irritable bowel syndrome (IBS). As compared to placebo, peppermint oil was found to be significantly superior for the improvement of the participant’s IBS symptoms and abdominal pain. The researchers conclude that “peppermint oil is a safe and effective short-term treatment for IBS.”

This study tested the effectiveness of peppermint oil in patients with irritable bowel syndrome. The results showed that, subjectively, “75% of the patients in the peppermint oil group showed a >50% reduction of basal total irritable bowel symptoms score compared with 38% in the placebo group.” Objectively, a statistically significant reduction of the total irritable bowel syndrome symptoms score was found with peppermint oil, but not with the placebo.
