Pimpinella, commonly known as anise or Pimpinella anisum, has a long history of traditional use for digestive complaints, including belching (eructation), flatulence, and mild dyspepsia. In traditional medicine systems such as Ayurveda and European herbalism, anise seeds are used as a carminative—an agent that helps expel gas from the gastrointestinal tract and relieve discomfort associated with bloating and belching. Historical texts and ethnobotanical records frequently mention the use of Pimpinella for this purpose, often in the form of teas, tinctures, or as a component of digestive mixtures.

Modern scientific research on the efficacy of Pimpinella specifically for belching is limited, with most clinical studies focusing on its general effects on digestion or use in mixtures with other herbs. Some in vitro and animal studies suggest that anise has antispasmodic and carminative properties, which could theoretically reduce gas and belching, but direct human evidence is lacking. Thus, the primary justification for its use in treating or supporting relief from belching is based on traditional practice rather than robust scientific validation.
