Caesalpinia crista (also known as Kantakari, Bonduc nut, or Fever nut) has a well-documented history in Ayurvedic and other traditional systems of medicine. Its seeds and other parts have been used to treat a variety of ailments, including hemorrhoids. In traditional texts, it is often mentioned for its purported ability to reduce inflammation, promote wound healing, and act as an astringent—properties that could be beneficial in managing hemorrhoidal symptoms such as swelling, bleeding, and discomfort.

However, the scientific evidence supporting the use of Caesalpinia crista specifically for hemorrhoids is limited. While some in vitro and animal studies suggest that the plant extracts possess anti-inflammatory, analgesic, and antimicrobial activities, there are no high-quality clinical trials or substantial pharmacological studies directly evaluating its efficacy for hemorrhoids in humans. Most of the support for its use in this condition comes from traditional knowledge, ethnobotanical surveys, and anecdotal reports. As such, the evidence rating is low (1 out of 5), reflecting that while traditional use is established, scientific validation is lacking.

In summary, the use of Caesalpinia crista for hemorrhoids is primarily justified by traditional practices, with minimal scientific evidence to confirm its effectiveness or safety for this specific indication.
