Rating (out of 5): 2
Boldo (Peumus boldus) has a long history of use in traditional medicine in South America, particularly in Chile, for a variety of digestive complaints, including belching (eructation), dyspepsia, and bloating. The leaves of boldo are used as a tea or infusion and are believed to have carminative and cholagogue effects—meaning they help to relieve gas and stimulate bile flow, which may support digestion. Historical texts and ethnobotanical surveys document its use for these purposes, often alongside other herbs. The presumed mechanism is related to its content of essential oils (such as ascaridole) and alkaloids (like boldine), which may have mild antispasmodic effects on the gastrointestinal tract.
However, scientific studies specifically investigating the efficacy of boldo for belching are very limited. Most available evidence comes from traditional usage and anecdotal reports rather than rigorously controlled clinical trials. Some laboratory studies indicate that boldo extracts can stimulate bile secretion and may have mild digestive effects, but direct evidence for its effectiveness in treating or reducing belching specifically is lacking. Therefore, while its use for belching is justified by traditional medicine, the scientific evidence base remains weak.
