Ajwain (Carom Seeds) for Bloating Relief

Research suggests that ajwain (Trachyspermum ammi) may offer relief from bloating and related gastrointestinal discomfort, with the evidence base drawing from a mix of clinical trials, mechanistic studies, and traditional use documentation. Two randomized controlled trials provide the most direct clinical support: one double-blind RCT found that a formulation containing ajwain significantly reduced bloating frequency and severity compared to both placebo and dimethicone, while a second clinical trial of an ajwain and celery combination reported symptom improvements in functional dyspepsia. Laboratory and pharmacological research offers plausible mechanisms, including demonstrated antispasmodic effects on gut smooth muscle and enhanced digestive enzyme activity in vitro, both of which align with ajwain's longstanding traditional classification as a carminative. Studies indicate that limitations exist, however, as several supporting sources are traditional use reviews or surveys rather than controlled trials, the clinical trials tested combination formulations rather than ajwain alone, and the overall body of high-quality human evidence remains modest in size, warranting further independent research before firm conclusions can be drawn.
