Charcoal poultices, typically made by spreading a paste of activated charcoal and water onto a cloth applied to the skin, have a long history in folk medicine traditions for drawing out irritants and supporting comfort after insect bites or minor skin concerns. Research suggests that activated charcoal's highly porous structure gives it notable adsorptive properties, meaning it may help bind certain toxins and irritants on the skin's surface. Some studies indicate that charcoal-based preparations could help reduce localized discomfort and swelling associated with insect stings, though rigorous clinical trials specific to poultice applications remain limited. While this remedy continues to be valued in home care practices around the world, individuals with open wounds or sensitive skin may want to explore the available evidence and consult a healthcare provider before use.
