Can Lavender oil cause breast growth in children?

by | Aromatherapy, Chemistry, Children, Essential Oils, Research, Safety

The claim that Lavender essential oil has been linked to pre-pubertal breast growth in children has been making the rounds since 2007. The most recent publication of cases, in 2019, catapulted this claim back into the spotlight, unfortunately with more sensationalism than solid evidence.

Watch a recording of Robert Tisserand’s presentation where he challenges the link between Lavender oil and actual cases, with the help of new laboratory analyses and an epidemiological study.
