Butea monosperma (commonly known as Flame of the Forest or Palash) has a history of use in traditional Ayurvedic medicine, where it is believed to have various health benefits, including supporting blood circulation. Classical Ayurvedic texts sometimes mention Butea monosperma as a component in formulations intended for cardiovascular health or for improving "rakta" (blood) quality and flow. These uses are generally based on empirical traditional knowledge rather than modern pharmacological validation.

Scientifically, there is limited research directly evaluating Butea monosperma for the treatment or support of poor circulation. A few preclinical studies have examined the plant's antioxidant and anti-inflammatory properties, which could theoretically have supportive effects on vascular health. For example, some extracts have shown vasodilatory and anti-inflammatory activity in animal models, but these studies are preliminary and not specific to the condition of poor circulation in humans. No robust human clinical trials have established its efficacy for this indication.

In summary, the use of Butea monosperma for poor circulation is primarily traditional, with anecdotal and historical support but only weak preclinical scientific evidence. Its role in supporting circulation remains to be confirmed by rigorous clinical studies.
