Kachnar (Bauhinia variegata) has a long-standing presence in traditional Ayurvedic medicine, where it is used for a variety of health conditions, including infections. The bark, flowers, and other parts of the plant are often incorporated into formulations intended to “cleanse the blood” and manage swelling or abnormal growths, but also occasionally in preparations for managing fevers and infections. The rationale for its use in infection, including viral infections, is largely based on ancient Ayurvedic texts and traditional use, rather than robust modern scientific validation. Modern scientific studies related specifically to antiviral activity of Kachnar are limited. Some preliminary in vitro studies suggest that extracts of Bauhinia variegata possess antimicrobial properties, but most research focuses on antibacterial, antifungal, or general anti-inflammatory effects rather than direct antiviral action. There is currently no strong clinical or laboratory evidence to support its efficacy specifically against viral infections in humans. In summary, the use of Kachnar for viral infection is rooted in tradition, with limited and indirect scientific support. Its use in this context should be regarded as traditional, and anyone considering Kachnar for this purpose should consult a healthcare professional.
