The use of the blackboard tree (Alstonia scholaris) for the treatment of constipation, especially in children, is primarily justified by traditional medicine rather than scientific validation. In various traditional medicinal systems across South and Southeast Asia, different parts of the blackboard tree, including its bark and leaves, have been employed for a variety of ailments, including digestive issues such as constipation. Folk healers sometimes administer preparations made from the bark, which is believed to have mild laxative properties. However, the evidence supporting its effectiveness for this indication is limited to anecdotal and ethnobotanical reports. There are few, if any, rigorous clinical studies evaluating the safety or efficacy of blackboard tree extracts for constipation in children. Most available research on Alstonia scholaris focuses on its antimicrobial, anti-inflammatory, and antimalarial properties, with scant attention to its effects on gastrointestinal motility or bowel habits. Furthermore, some constituents of the plant can be toxic at higher doses, raising safety concerns, especially in pediatric populations. In summary, while there is a tradition of using blackboard tree in some cultures for constipation, scientific validation is lacking, and caution is advised until further studies establish its safety and efficacy for this use.
