A recent study suggests that turmeric, the spice responsible for giving curry its yellow color, may be as effective as conventional drugs in treating indigestion. Scientists believe that considering the use of turmeric in clinical practice could be justified based on these findings.
The study, published online in BMJ Evidence-Based Medicine, revealed that curcumin, a natural compound found in turmeric, could potentially match the effectiveness of omeprazole, a medication used to reduce excess stomach acid, in alleviating indigestion symptoms. Professor Krit Pongpirul, from Chulalongkorn University Faculty of Medicine in Thailand and the study author, highlighted that turmeric, derived from the Curcuma longa plant’s root, contains curcumin known for its anti-inflammatory and antimicrobial properties and has been historically used in South East Asia for medicinal purposes, including indigestion treatment.
To investigate turmeric’s efficacy compared to conventional medications, the research team conducted a 28-day trial involving 206 patients aged 18 to 70 suffering from functional dyspepsia, a recurring upset stomach. The participants were divided into three treatment groups: turmeric with curcumin capsules, omeprazole, and a combination of turmeric and omeprazole.
Functional dyspepsia symptoms include feeling overly full after meals, early satiety, and stomach or food pipe discomfort. While omeprazole is a common proton pump inhibitor used to treat these symptoms, its long-term use has been associated with potential risks such as bone fractures, nutrient deficiencies, and increased infection susceptibility.
After the trial period, the participants showed significant improvements in symptom severity, particularly in pain and other symptoms, as measured by the Severity of Dyspepsia Assessment score (SODA). The study revealed that both curcumin and omeprazole groups experienced notable reductions in symptoms, with curcumin users showing consistent satisfaction scores over time, possibly due to taste preferences.
Although some participants using curcumin displayed mild liver function test abnormalities, no serious side effects were reported. Despite the study’s limitations, including its small size and short duration, Professor Pongpirul emphasized the need for larger, longer-term studies to validate these initial findings. He concluded that the results of this randomized controlled trial provide compelling evidence supporting turmeric’s potential in treating functional dyspepsia, warranting further consideration of curcumin in clinical practice.
