Colombo (Jateorhiza palmata), also known as calumba, is a traditional herbal remedy primarily used in African and European herbal medicine. Its main application has historically been as a bitter tonic to stimulate appetite and aid digestion. The roots contain alkaloids (such as jateorhizine), bitter principles, and starches. In traditional systems, especially European and colonial-era herbalism, Colombo was used to address digestive complaints including indigestion, flatulence, and belching. The rationale for its use in belching (eructation) comes from the general belief that bitter tonics improve gastric function, promote secretion of digestive juices, and thus reduce symptoms associated with slow or weak digestion, including gas and belching.

However, there is a paucity of modern scientific studies specifically examining Colombo’s effects on belching or eructation. The mechanism is presumed to be similar to other bitters: by stimulating the gustatory nerves, bitters are thought to enhance saliva and gastric secretions, potentially improving digestion and mitigating upper gastrointestinal discomfort. Despite this traditional use, there is limited clinical evidence directly supporting Colombo’s efficacy for belching. Most evidence remains anecdotal or extrapolated from its general use as a digestive aid in herbal formularies and traditional medicine references.

In summary, Colombo’s use for belching is primarily rooted in traditional herbal practices rather than rigorous scientific validation, and the evidence supporting its specific use for this symptom is weak.
