Piper nigrum (black pepper) has a long history of use in traditional medicine systems, particularly Ayurveda and Traditional Chinese Medicine, for a variety of digestive complaints, including belching (eructation), indigestion, and flatulence. The traditional rationale is that black pepper stimulates digestive fire ("agni"), increases saliva and gastric juice secretion, and thereby improves digestive efficiency and reduces symptoms like bloating and belching. The active compound, piperine, is thought to enhance gastrointestinal motility and enzymatic activity, although these effects are primarily inferred from traditional use and general studies on digestion.

Scientific studies directly evaluating Piper nigrum for belching are lacking. While some research supports its role in enhancing digestive enzyme secretion and improving bioavailability of other substances, there is insufficient direct clinical evidence linking black pepper or piperine to a reduction in belching specifically. Most supporting data come from animal studies or broader assessments of digestive health. Thus, the use of black pepper for belching is justified primarily by traditional practice rather than scientific validation, and the evidence remains limited.
