Menthae piperitae folium - herbal medicinal product
European Medicines Agency
EMA recognizes traditional use of peppermint leaf for indigestion and flatulence; this does not convert IBS peppermint-oil evidence into a generic leaf claim.
Reviewed guidance
Peppermint leaf for intestinal gas
Peppermint leaf has recognized traditional use for digestion-related complaints such as indigestion and flatulence. This is distinct from the stronger, condition-specific evidence for enteric-coated peppermint oil in IBS.
What this means
Traditional short-term relief of digestion-related symptoms including flatulence using peppermint-leaf preparations.
How to use it: Keep peppermint leaf and peppermint oil separate. A broad intestinal-gas claim should not borrow IBS evidence from enteric-coated peppermint oil or treat essential oil as interchangeable with leaf tea.
Safety & cautions
Peppermint leaf can worsen heartburn or reflux. People with gallstones or other biliary problems should use caution. Do not ingest undiluted peppermint essential oil as a substitute for a labeled oral product.
Get medical care for symptoms that are severe, last longer than expected, get worse, or otherwise concern you.
Household preparations
Practical ways to use the ingredient may not provide the same form or amount discussed in the evidence.
