Synopsis

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

Gigartina, a genus of red algae, has been traditionally used in various cultures for its potential health benefits, including support for skin health and the management of skin infections. Historically, Gigartina species have been valued in folk medicine, particularly in coastal regions where seaweeds are a common part of the materia medica. Preparations from Gigartina have been topically applied to the skin to help soothe irritation, promote wound healing, and potentially combat superficial infections. The rationale for these uses is often attributed to the presence of sulfated polysaccharides (such as carrageenans), which may have mild antimicrobial and anti-inflammatory properties based on in vitro studies.

However, while there is some preliminary laboratory evidence showing that extracts from Gigartina can inhibit the growth of certain bacteria and viruses, robust clinical data in humans are lacking. No large-scale controlled trials have confirmed its efficacy for treating or preventing skin infections. Most of the support for this use comes from anecdotal reports and traditional practices rather than from rigorous scientific validation. As such, Gigartina’s use for skin infections remains primarily supported by tradition, with limited evidence from modern biomedical research.
