Henna (Lawsonia inermis) has been traditionally used in various cultures for its soothing and cooling properties, including as a topical application for skin irritations such as itching. In regions of South Asia, the Middle East, and North Africa, folk medicine often recommends henna paste for rashes, eczema, and pruritus (itching), attributing relief to its natural cooling effect and possible anti-inflammatory actions. The leaves are ground into a paste and applied directly to affected areas.

From a scientific standpoint, there are a few in vitro and animal studies suggesting that henna possesses anti-inflammatory, antimicrobial, and antioxidant properties, which could theoretically help with conditions causing skin irritation or itching. However, robust clinical trials or systematic reviews supporting its efficacy specifically for pruritus in humans are lacking. The absence of large-scale, well-designed studies means current evidence is limited and primarily anecdotal. Some small studies and traditional reports note improvement in symptoms, but these are not sufficient to form a strong evidence base.

In summary, while the use of henna for itching is grounded in traditional practices and supported by preliminary, low-level scientific evidence for related properties, it cannot be considered scientifically validated for this specific indication. Individuals should also be aware of potential allergic reactions to henna, which could worsen itching in some cases.
