peppermint oil + caraway oil

This is a fixed-dose herbal combination consisting of peppermint oil (Mentha x piperita L.) and caraway oil (Carum carvi L.), specifically developed by Dr. Willmar Schwabe (often referred to by the code WS 1520). It is primarily indicated for the treatment of functional gastrointestinal disorders, including functional dyspepsia and irritable bowel syndrome (IBS). The mechanism of action is multi-targeted: peppermint oil acts as a local spasmolytic on the smooth muscles of the gastrointestinal tract by blocking voltage-gated calcium channels, while caraway oil exerts carminative effects and acts synergistically to reduce bloating, flatulence, and abdominal pain. The formulation is typically enteric-coated to bypass the stomach and target the intestines, thereby reducing the risk of gastrointestinal reflux or heartburn associated with peppermint oil.
