Boerhavia diffusa, commonly known as "Punarnava," is a plant widely used in traditional Ayurvedic medicine. Its use for dyspepsia (indigestion) is primarily based on traditional knowledge rather than robust scientific validation. In Ayurvedic texts, Boerhavia diffusa is described as having "deepana" (appetizer) and "pachana" (digestive) properties and is often included in formulations intended to alleviate digestive disorders such as loss of appetite, abdominal discomfort, and indigestion.

The ethnobotanical use of Boerhavia diffusa for digestive complaints is supported by its inclusion in several classical Ayurvedic preparations for dyspepsia and related gastrointestinal disturbances. Some preclinical studies suggest that extracts of Boerhavia diffusa may possess mild digestive stimulant and anti-inflammatory effects, which could theoretically contribute to symptomatic relief in dyspepsia. However, controlled clinical trials specifically evaluating its efficacy for dyspepsia in humans are lacking.

Therefore, the use of Boerhavia diffusa for dyspepsia is justified by a long-standing tradition and historical usage, but scientific evidence remains limited and indirect. Its use should be considered as adjunctive and guided by traditional practices rather than modern clinical data.
