Morinda, often referring to Morinda citrifolia (commonly known as noni), has a history of use in traditional medicine systems, particularly in Polynesia, Southeast Asia, and parts of India. In these traditional contexts, various parts of the Morinda plant—including leaves, fruit, and roots—have been used for a range of skin conditions, including eczema (also known as atopic dermatitis). Preparations such as crushed leaves or topical applications of noni juice have been applied to the skin with the aim of reducing inflammation, itching, and infection.

However, scientific evidence supporting the effectiveness of Morinda species for eczema is extremely limited. A few laboratory studies have indicated that noni possesses anti-inflammatory and antioxidant properties, which could theoretically benefit inflammatory skin conditions. Yet, there is a lack of clinical trials specifically evaluating Morinda’s efficacy for eczema in humans. No major dermatological guidelines include Morinda as a recommended treatment. Thus, while traditional use exists and there is some plausibility based on basic pharmacological properties, the overall level of supporting evidence remains weak and primarily anecdotal.

In summary, Morinda’s use for eczema is based on traditional practices, but robust clinical evidence is lacking.
