Synopsis

Rating (out of 5): 2

Ylang ylang (Cananga odorata) essential oil has been used traditionally in aromatherapy and folk medicine to promote relaxation, reduce stress, and support emotional well-being. Its use is rooted in traditional practices, particularly in Southeast Asia, where the flowers are used in rituals and personal care for their calming scent. The rationale for its application to support the parasympathetic nervous system—a branch of the autonomic nervous system responsible for “rest and digest” functions—comes primarily from these traditions.

Some small-scale studies and anecdotal reports suggest that inhalation of ylang ylang essential oil may induce relaxation and reduce physiological markers of stress, such as heart rate and blood pressure. For example, a few clinical trials have noted reductions in heart rate and blood pressure following ylang ylang inhalation, which may be interpreted as activation of the parasympathetic nervous system. However, these studies are limited in size, design, and replication, and the overall scientific evidence is weak and not conclusive.

Thus, while there is a traditional basis for using ylang ylang to support relaxation and potentially parasympathetic activity, robust scientific validation is lacking. Most claims rely on its historical use and limited preliminary research rather than strong, consistent scientific evidence.
