Butea monosperma, commonly known as "flame of the forest," has a well-established history of use in traditional Ayurvedic and folk medicine in India. Regarding afterbirth pain (the discomfort experienced by women following childbirth due to uterine contractions as the uterus returns to its pre-pregnancy size), several ethnobotanical surveys and classical Ayurvedic texts mention the use of various parts of Butea monosperma, especially its flowers and bark, for managing postnatal conditions, including pain and inflammation. These uses are largely based on its reputed anti-inflammatory, analgesic, and uterine tonic properties in traditional systems.

However, direct scientific validation for Butea monosperma specifically addressing afterbirth pain in humans is limited. Pharmacological studies have shown that extracts of the plant possess anti-inflammatory and analgesic activities in animal models, which could theoretically provide relief from afterbirth pain. These findings offer some biological plausibility for its traditional use, but there are no controlled clinical trials or robust scientific studies specifically investigating its effectiveness for afterbirth pain in postpartum women.

In summary, Butea monosperma’s use for afterbirth pain is primarily supported by tradition, with a modest pharmacological foundation, but lacks direct clinical evidence. The rating reflects the presence of traditional evidence and some supporting mechanism from laboratory studies, but the absence of direct clinical research for this particular indication.
