Bisabolol is a naturally occurring compound found in chamomile (Matricaria recutita) and other plants, known for its anti-inflammatory, soothing, and antimicrobial properties. Its use in the management of cold sores (herpes labialis) is primarily supported by its ability to reduce inflammation and potentially inhibit viral activity, though direct evidence is limited.

Laboratory studies have shown that bisabolol can suppress inflammation and may have mild antiviral effects, including some activity against herpes simplex virus (HSV), the causative agent of cold sores. For example, in vitro research suggests bisabolol can reduce HSV-1 replication, but these effects are generally modest compared to standard antiviral drugs like acyclovir. Additionally, bisabolol’s anti-inflammatory and skin-soothing actions can alleviate symptoms such as redness, swelling, and discomfort associated with cold sores, which may contribute to its inclusion in topical treatments.

Clinical evidence, however, remains sparse. Most studies evaluating topical cold sore treatments containing bisabolol include it as one component in multi-ingredient formulations, making it difficult to isolate its specific benefits. There are few, if any, high-quality randomized controlled trials directly investigating bisabolol as a standalone treatment for cold sores.

In summary, bisabolol is included in some cold sore products due to its anti-inflammatory and mild antiviral effects, but the scientific evidence supporting its efficacy is limited. It may provide symptomatic relief, though it is not a replacement for established antiviral therapies.
