Lebbek (Albizia lebbeck) is primarily used in traditional medicine systems such as Ayurveda and Unani for various skin conditions, including eczema. The bark and leaves of Lebbek have been employed for their anti-inflammatory, antipruritic, and astringent properties. Historical texts mention its use for alleviating itching and soothing irritated skin, which aligns with some of the symptoms of eczema (atopic dermatitis). However, direct references to its use specifically for "eczema" are mostly interpretative, as ancient descriptions often refer to broader skin ailments rather than the modern clinical definition of eczema.

Scientific studies on Lebbek's effects on eczema are sparse. Some in vitro and animal studies suggest that extracts of Albizia lebbeck possess anti-inflammatory and antioxidant activities, which could theoretically be beneficial for inflammatory skin disorders. For example, a few studies have shown that Lebbek bark extract can inhibit histamine release and reduce edema in experimental models, lending some plausibility to its traditional use for pruritic (itchy) conditions.

Nonetheless, there is a lack of robust clinical trials or direct research on humans specifically evaluating Lebbek for eczema. Therefore, its use for eczema is justified primarily by traditional practice rather than strong scientific validation, and the supporting evidence is limited.
