Synopsis

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

The use of orange pigment, specifically mercuric oxide (often referred to as “red mercuric oxide” or “orange pigment” due to its color), for treating cuts and wounds has traditional roots rather than being validated by modern scientific evidence. Historically, mercuric oxide was used as a topical antiseptic and wound dressing in the early to mid-20th century before the risks of mercury toxicity were well understood. Its vivid orange color made it a recognizable treatment in some regions and settings. However, there is minimal high-quality scientific data supporting its efficacy in wound healing or infection control compared to modern antiseptics. The pigment’s antimicrobial properties were the rationale for its use, yet the significant risk of mercury absorption and toxicity has led to its discontinuation in most medical contexts. Current medical guidelines do not recommend orange pigment (mercuric oxide) for cuts, and safer, more effective alternatives are preferred. Thus, while its use is justified by historical practice, it lacks robust scientific validation, and its application today is generally considered obsolete and potentially hazardous.
