Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Punarnava (Boerhavia diffusa) has been traditionally used in Ayurveda and other traditional systems of medicine in India for a variety of ailments, including respiratory conditions such as cough. In the context of spastic cough—a cough characterized by spasms or fits—punarnava is valued primarily for its expectorant, anti-inflammatory, and antispasmodic properties as described in classical Ayurvedic texts. Historically, it has been included in formulations aimed at managing bronchial conditions, reducing mucus, and soothing irritated airways. Its Sanskrit name, meaning "renewed" or "rejuvenated," reflects its broader use in revitalizing health and addressing fluid imbalances, which can be related to respiratory discomfort.

From a scientific perspective, there are some preclinical studies indicating that punarnava possesses anti-inflammatory and mild antitussive (cough-suppressing) effects, but robust clinical evidence specifically for spastic cough is lacking. Most of the current scientific literature focuses on its diuretic, hepatoprotective, and anti-inflammatory actions rather than direct effects on cough. Thus, its use for spastic cough is primarily justified by traditional use and anecdotal reports, rather than strong scientific validation. The evidence rating of 2 reflects the presence of some supportive traditional documentation and limited preliminary pharmacological research, but an absence of well-designed clinical trials for this specific indication.
