Bisabolol

Bisabolol is a sesquiterpene alcohol most recognized for its prominent role in German chamomile (Matricaria chamomilla), where it comprises up to 50% of the essential oil. This compound exists in two primary forms: α-bisabolol (levomenol) and β-bisabolol, with the alpha form being the most therapeutically active and widely studied [1]. Beyond chamomile, bisabolol appears naturally in candeia tree (Eremanthus erythropappus) bark, Brazilian rosewood, and various mint species.

What sets bisabolol apart from other terpenes is its exceptional stability and bioavailability when applied topically. Unlike many volatile terpenes that rapidly degrade or fail to penetrate skin barriers effectively, bisabolol maintains its molecular integrity and demonstrates consistent absorption rates [2]. This stability explains why it has become a cornerstone ingredient in pharmaceutical and cosmetic formulations, particularly in European markets where chamomile-based medicines hold official monograph status.
