Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Purified silver, particularly in the form of silver sulfadiazine cream, has a well-established role in the management of skin lesions, especially burns and chronic wounds. The antimicrobial properties of silver have been known for centuries, but scientific validation came with the development and clinical adoption of silver-containing dressings and creams. Silver ions (Ag+) disrupt bacterial cell membranes and interfere with microbial DNA, making them effective against a wide range of pathogens, including antibiotic-resistant strains. Multiple clinical studies and reviews support the efficacy of silver-based products in reducing wound infection rates, promoting healing, and improving outcomes in burn patients. For example, a 2017 systematic review published in "Burns" journal confirmed that silver sulfadiazine is effective in preventing wound infection, though it may not necessarily speed wound closure compared to some newer dressings. Other preparations, such as nanocrystalline silver dressings, have also shown promise for chronic ulcers and diabetic foot lesions, although evidence for accelerated healing is mixed. The use of purified silver for lesions is therefore justified by both historical tradition and modern scientific research, with the latter providing moderate-quality evidence for its antimicrobial and wound-management benefits. However, concerns about cytotoxicity, delayed healing in some wound types, and potential for argyria (skin discoloration) limit indiscriminate use. Current guidelines recommend silver-based treatments primarily for infected or high-risk wounds rather than all lesions.
