Peppermint oil has a long history in traditional medicine for supporting digestive health, including issues related to the gall bladder. In folk and herbal medicine, peppermint oil has been used to relieve symptoms such as indigestion, bloating, and biliary colic (pain related to the gall bladder). The rationale is largely based on the oil's antispasmodic properties—primarily due to its menthol content—which can relax smooth muscle in the gastrointestinal tract. This traditional use is documented in various herbal pharmacopeias and texts, especially in European and Middle Eastern traditions.

From a scientific perspective, most clinical studies on peppermint oil have focused on its effects in the context of irritable bowel syndrome (IBS) and general dyspepsia, rather than specifically on gall bladder function or diseases such as gallstones or cholecystitis. There is limited direct scientific evidence that peppermint oil supports the gall bladder itself. However, some studies have shown that menthol can relax the sphincter of Oddi (the muscle controlling bile flow from the gall bladder), which may theoretically ease biliary pain. Still, this effect has not been widely studied or confirmed in large clinical trials specifically targeting gall bladder health.

In summary, while peppermint oil is widely used in traditional medicine to support the gall bladder and relieve related digestive discomfort, scientific validation for this specific application is weak. The evidence base primarily supports its traditional, not scientific, use.
