Scientists have discovered that lavender, a scented flower, relaxes and can help people relax and could even be a safer alternative to anxiety medications.
The study conducted on mice showed that the drug sprayed lavender linalool compound should be felt – not absorbed by the lungs – to feel the soothing effects, which could be used to relieve stress and preoperative anxiety disorders.
Mice exhibit fewer signs of anxiety when they smell the scented flower.
"In traditional medicine, it's long been believed that odorous compounds derived from plant extracts can relieve anxiety," said Hideki Kashiwadani, co-author of Kagoshima University's Japan.
The scented flower can also serve as an alternative to current anxiolytics (anxiolytics) such as benzodiazepines, known to cause memory problems, bad growth in humans and birth defects.
In the study published in Frontiers in Behavioral Neuroscience, research rs tested mice to see if it's the smell of linalool – that is, the stimulation of olfactory neurons ( odor-sensitive) in the nose – triggering relaxation.
They discovered that the linalool odor had an anxiolytic effect in normal mice. However, that did not stop their movement.
This contrasts with benzodiazepines and linalool injections, whose effects on movements are similar to those of alcohol.
"The results suggest that linalool does not act directly on GABAA receptors, unlike benzodiazepines, but must activate them via olfactory neurons on the nose in order to produce its relaxing effects," Kashiwadani explained.
"Our study also opens the possibility that the relaxation observed in linalool-fed or linalool-fed mice is actually due to the odor of the compound emitted by their expired breath."
Lavender could also be used in pre-surgery or by those who have trouble getting on drugs, the team said.
