Curcuma, most commonly referring to Curcuma longa (turmeric), has been used both traditionally and in modern phytotherapy for digestive complaints, including dyspepsia. The scientific evidence supporting its use in dyspepsia is moderate. Several randomized controlled trials and systematic reviews have evaluated turmeric extracts and their active constituents (notably curcumin) for their ability to alleviate symptoms of functional dyspepsia, such as bloating, gastric discomfort, and early satiety. These studies generally indicate that turmeric may reduce symptoms compared to placebo, with efficacy comparable to some conventional treatments like prokinetic drugs. The proposed mechanisms include stimulation of bile production, anti-inflammatory effects, and modulation of gastric motility. However, the quality of evidence is limited by relatively small sample sizes, heterogeneity in formulations and dosages, and short study durations. While most studies report turmeric to be well-tolerated, high-quality, large-scale trials are still needed to confirm efficacy and establish optimal dosing. Regulatory bodies such as the European Medicines Agency (EMA) recognize turmeric rhizome preparations as traditional herbal remedies for digestive disturbances, further supporting its use. In summary, the use of Curcuma for dyspepsia is supported by both traditional use and a growing body of scientific literature, though more robust clinical data would help to solidify its position in evidence-based medicine.
