Bisabolol is a naturally occurring monocyclic sesquiterpene alcohol, most commonly derived from German chamomile (Matricaria recutita). It is widely used in traditional herbal remedies for its soothing and healing properties, but its use to support or treat infection has some degree of scientific backing. Laboratory studies have shown that bisabolol exhibits antimicrobial activity against a range of bacteria and fungi, including Staphylococcus aureus and Candida albicans. The mechanism is thought to involve disruption of microbial cell membranes and inhibition of biofilm formation, thereby reducing the ability of microorganisms to colonize and proliferate.

Clinical data, however, is limited. Most evidence comes from in vitro (test tube) studies or animal models, with few well-controlled human trials evaluating bisabolol as a stand-alone antimicrobial agent. In topical formulations, bisabolol is often included to support skin barrier function, reduce irritation, and potentially lower infection risk in minor wounds or dermatological conditions. Its anti-inflammatory and soothing effects may provide additional benefits in such contexts.

Overall, while there is laboratory evidence supporting bisabolol’s antimicrobial properties, clinical validation is modest, especially regarding its use as a primary agent for treating established infections. Its main value currently appears to be as an adjunct in topical preparations, where it may help reduce infection risk in combination with other ingredients. Further clinical research is needed to establish its efficacy and safety as an infection-fighting agent in humans.
