Synopsis

Source of validity: Traditional
Rating (out of 5): 1

The use of the blackboard tree (Alstonia scholaris) for the treatment of hemorrhoids is primarily rooted in traditional medicine practices, especially in South and Southeast Asia. Traditional healers have used various parts of the tree—such as the bark, latex, or leaves—for their purported anti-inflammatory and astringent properties. In Ayurvedic and folk medicine, decoctions or pastes made from the bark are sometimes applied to affected areas or consumed to alleviate symptoms associated with hemorrhoids. The rationale behind this use is based on the general belief in the plant’s ability to reduce inflammation, promote healing, and provide relief from pain and swelling.

However, scientific validation for these effects is limited. While some laboratory studies have identified anti-inflammatory and antimicrobial properties in extracts of Alstonia scholaris, there is a lack of high-quality clinical trials or pharmacological studies specifically evaluating its efficacy in the treatment of hemorrhoids. Most of the available evidence is anecdotal or derived from broader studies on traditional medicinal plants. Therefore, the support for its use in hemorrhoids is weak from a scientific standpoint, and further research would be necessary to confirm any therapeutic benefits.

In summary, the use of blackboard tree for hemorrhoids is based on tradition rather than robust scientific evidence.
