Holy Basil (Tulsi) for Respiratory Health

Research suggests that holy basil (tulsi) may have therapeutic potential for respiratory conditions such as asthma, bronchitis, colds, and cough, with its bioactive compounds — including flavonoids, terpenoids, and alkaloids — thought to underlie these effects. The available evidence, however, is largely limited to a single narrative review drawing on traditional use and preclinical findings, with no clinical trials, randomized controlled studies, or meta-analyses currently represented in this summary. Studies indicate that while certain medicinal plants including tulsi show promise as adjuvant treatments for respiratory ailments and as sources of novel therapeutic agents, the authors of the review themselves acknowledge that much of the supporting evidence remains preliminary. Readers should be aware that the current body of research does not yet establish efficacy in humans, and more rigorous clinical investigation is needed before firm conclusions can be drawn.
