Aromatherapy can be used with minimal risk when it is supervised by caregivers.
Essential oils are used by health professionals, mainly via the olfactory route in the emotional sphere. They improve the well-being of patients as a complementary approach.
Inhalation provides an immediate effect through the passage of aromatic molecules into the nasal mucosa and stimulation of the olfactory bulb. Dry inhalation from a stick does not a priori present any risk of drug interaction. The oils used in hospitals for their benefits on the emotional sphere, are considered to be the least toxic.
