Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Caraway (Carum carvi) seeds have a long history of use in traditional medicine systems, particularly in Europe and the Middle East, for alleviating digestive complaints such as gas (flatulence) and bloating. This use is rooted in traditional herbalism, where caraway is often included in "carminative" formulations—remedies aimed at relieving discomfort from gas and aiding digestion. Traditional sources, including folk medicine and historical pharmacopeias, recommend caraway seeds as an after-meal digestive aid, sometimes in combination with other herbs like fennel or anise.

From a mechanistic perspective, caraway contains volatile oils (notably carvone and limonene) that are thought to relax the smooth muscles of the gastrointestinal tract, potentially reducing spasms and facilitating the passage of gas. While there is some preliminary scientific evidence and a handful of small clinical studies suggesting benefits for functional dyspepsia (indigestion), often in combination with peppermint oil, the evidence specifically for gas and bloating is limited and does not meet the standards of robust clinical validation. Most clinical trials focus on combination products, making it challenging to isolate the effect of caraway alone.

In summary, the use of caraway for gas and bloating is primarily justified by traditional use, supported by plausible mechanisms and limited scientific investigation, but high-quality, large-scale clinical trials are lacking. Thus, the evidence is rated as moderate for traditional use, with some emerging, but not definitive, scientific backing.
