Synopsis

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

The use of the blackboard tree (Alstonia scholaris) for treating ear infections or earache is primarily based on traditional medicine, particularly in South and Southeast Asian countries. In Ayurveda and various folk medicinal systems, extracts from the bark, leaves, or latex of the blackboard tree are sometimes used externally or as ear drops to relieve ear pain and manage infections. However, scientific validation for this specific use is limited. Some studies have reported that Alstonia scholaris possesses antimicrobial, anti-inflammatory, and analgesic properties, which could theoretically contribute to relief from ear infections or earaches. Nevertheless, these studies are mostly preclinical, conducted in vitro or on animal models, and do not specifically address ear conditions. No robust clinical trials or systematic reviews confirm its efficacy or safety for otic (ear) applications in humans. Additionally, the latex and extracts can be irritant or toxic if misused. In summary, while there is a traditional basis for using blackboard tree preparations to treat ear ailments, strong scientific evidence and safety data supporting this practice are lacking. People considering such remedies should exercise caution and consult qualified healthcare professionals before use.
