Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Castile soap is primarily used for its cleansing properties and has a long history of traditional use for skin hygiene, including cleaning minor wounds and supporting general skin health. The soap, originally made from olive oil in the Castile region of Spain, is known for being gentle and natural compared to harsher chemical soaps. Historically, people have used Castile soap to clean skin affected by minor infections or irritations, under the belief that keeping the area clean would support healing. However, there is limited direct scientific evidence that Castile soap itself treats skin infections. Most of its benefit comes from its ability to remove dirt, debris, and some microbes from the skin’s surface, which may help reduce the risk of infection or prevent worsening, rather than actively treating existing infections. Unlike antibacterial soaps, Castile soap does not contain added antimicrobial agents. Its traditional use in wound care and skin cleansing is well documented, but clinical studies specifically validating its use as a treatment for skin infections are lacking. Therefore, while Castile soap is valued for its mildness and effectiveness as a cleanser, its direct role in treating skin infections is supported more by tradition and basic hygiene principles than by robust scientific validation.
