Punarnava for Anti-Inflammatory

Research suggests that Punarnava (Boerhaavia diffusa) possesses anti-inflammatory properties attributable to a range of bioactive compounds, including flavonoids, phenolics, alkaloids, and rotenoids, as identified in preclinical and laboratory studies. The available evidence comes entirely from review articles rather than clinical trials, meaning direct human evidence is currently lacking, though both reviews consistently support the plant's anti-inflammatory potential. Studies indicate that much of the observed anti-inflammatory activity may be linked to the plant's broader antioxidant properties, and researchers have noted that many individual bioactive constituents remain underexplored. A notable limitation across the literature is the low bioavailability of the plant's active compounds, and scientists are investigating nanocarrier-based delivery strategies to address this challenge, underscoring that substantial further research — including controlled human trials — is needed before firm conclusions can be drawn.
