Indian mallow (Abutilon indicum) has a long history of use in traditional medicine systems, particularly in Ayurveda, Siddha, and Unani practices in India. For the treatment of external bleeding, various parts of the plant, especially the leaves, have been used topically as poultices or pastes. These preparations are believed to help staunch bleeding and promote wound healing. The traditional rationale often cites the plant's purported astringent and soothing properties, which may help constrict blood vessels and facilitate clotting when applied to minor wounds or abrasions.

In terms of scientific validation, there are limited studies directly evaluating the hemostatic effects of Abutilon indicum on external bleeding. Some in vitro and animal studies have reported anti-inflammatory, antimicrobial, and wound healing activities, which could indirectly support its use in managing wounds and minor bleeding. However, these studies are preliminary and do not specifically measure effects on external bleeding in humans. As such, the use of Indian mallow for this purpose is primarily justified by traditional knowledge, with modest supportive evidence from general wound-healing research but lacking direct clinical trials or robust scientific validation for hemostatic properties.
