Rating (out of 5): 2

Bentonite clay has been traditionally used for various skin ailments, including lesions, wounds, and dermatological irritations. Its use is rooted in folk medicine across different cultures, where it has been applied topically to support healing, absorb exudates, and provide a protective barrier against infection. The clay’s absorptive properties are believed to draw out impurities, toxins, and excess moisture, which may help keep lesion areas clean and reduce inflammation. Historical texts and ethnobotanical records document its use for minor wounds, ulcers, and insect bites. However, scientific validation for bentonite’s effectiveness in treating skin lesions is limited. A small number of in vitro and animal studies suggest that bentonite may have mild antibacterial properties, and its absorptive nature can help with moisture control. Some recent investigations have explored its use in wound dressings or as an adjunct in treating diabetic ulcers, but these studies are preliminary and not conclusive. No large-scale, high-quality clinical trials have established bentonite clay as an evidence-based treatment for lesions in humans. Current medical guidelines do not endorse bentonite for lesion management, but its generally low risk profile (when used externally) and long-standing traditional use mean it is sometimes included in alternative or complementary approaches. Users should exercise caution, as improper use can cause irritation or interfere with wound healing.
