Bisabolol is a natural monocyclic sesquiterpene alcohol found primarily in chamomile (Matricaria recutita). It is widely recognized for its anti-inflammatory, soothing, and skin-calming properties. The use of bisabolol in supporting or treating itching ears is supported by scientific evidence, albeit largely indirect and of moderate strength.

Topical bisabolol has been shown in several studies to reduce skin irritation, redness, and inflammation due to its ability to inhibit pro-inflammatory cytokines and support the skin barrier. These properties are relevant to conditions such as pruritus (itching) that often result from irritation, mild dermatitis, or allergic reactions in the ear canal. While there are no large-scale, direct clinical trials evaluating bisabolol specifically for itching ears, its inclusion in products designed for otic (ear) use is typically based on its general dermatological efficacy and its excellent safety profile.

Some over-the-counter ear drops and skin care preparations use bisabolol as a key ingredient to soothe irritated or itchy skin, leveraging its ability to calm the skin and reduce sensations of discomfort. However, the evidence base is largely extrapolated from studies on other parts of the body, rather than direct studies of the ear canal. Thus, while there is a scientific rationale and supportive evidence from dermatological research, more targeted studies are needed to fully validate its effectiveness for itching ears specifically.
