Synopsis

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

Iodine is scientifically validated for use in supporting and treating infections, particularly as a topical antiseptic. Its antimicrobial properties have been recognized since the 19th century, and it remains a cornerstone in infection control protocols. Iodine, especially in the form of povidone-iodine, acts by rapidly penetrating microbial cell walls and inactivating proteins and nucleic acids, leading to cell death. Peer-reviewed studies have consistently demonstrated its broad-spectrum efficacy against bacteria (including antibiotic-resistant strains like MRSA), viruses, fungi, and protozoa. It is commonly used to disinfect skin prior to surgery, clean wounds, and sterilize medical equipment.

The World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) both list iodine-based solutions as effective antiseptics. Clinical trials and laboratory studies rate its effectiveness highly, with minimal resistance reported. While oral or systemic iodine is not typically used to treat infections (except in severe iodine deficiency affecting immune function), topical application is standard in medical and first aid settings worldwide.

In summary, iodine’s use for infection is not only traditional but is also strongly supported by scientific evidence and global medical guidelines, making it a gold standard for topical infection prevention and minor wound care.
