Sage-leaf alangium (Alangium salviifolium) is a plant used in various traditional medicine systems, particularly in South Asia and parts of Southeast Asia. In Ayurveda and some folk medicinal practices, parts of the plant—such as the roots and leaves—are used to treat a range of ailments, including dizziness, vertigo, and nervous disorders. The use for dizziness is primarily based on traditional herbal knowledge rather than modern pharmacological validation.

The rationale in traditional texts is often linked to the supposed calming, nervine, and anti-inflammatory properties of the plant, with preparations sometimes administered as decoctions or infusions. However, a review of contemporary scientific literature reveals a lack of robust clinical studies or pharmacological investigations specifically examining the efficacy of Alangium salviifolium for dizziness or vertigo. While some studies indicate potential CNS (central nervous system) activity or antioxidant effects, these do not directly substantiate its use for dizziness in a controlled or clinical context.

In summary, the application of sage-leaf alangium for dizziness is grounded in traditional use, with very limited or indirect scientific evidence to support its effectiveness for this specific indication.
