Peppermint for Digestive Health

Research suggests that peppermint, particularly in oil form, has been discussed in the scientific literature as a potential dietary supplement for managing digestive symptoms, especially in the context of irritable bowel syndrome, where one 2022 review identified it alongside other dietary strategies as a tool for addressing gut microbiome imbalance and symptom relief. However, the overall picture is mixed. A 2025 systematic review examining plant-based digestive supplements found that while peppermint is among the most commonly included ingredients in commercial products marketed for conditions like bloating, reflux, and dyspepsia, the majority of associated health claims rest primarily on traditional use rather than robust clinical evidence. The available evidence here draws from review-level literature rather than direct randomized controlled trials or meta-analyses, and researchers in both studies emphasize the need for more standardized preparations and rigorous clinical research before strong conclusions about efficacy can be drawn.
