Essential oils, which are obtained through mechanical pressing or distillation, are concentrated plant extracts that retain the natural smell and flavor of their source.
Each essential oil has a unique composition of chemicals, and this variation affects the smell, absorption, and effects on the body. The chemical composition of an essential oil may vary within the same plant species, or from plant to plant.
Synthetic oils are not considered true essential oils.

What age range are boys at risk for gynecomastia?
Male gynecomastia is a common clinical symptom observed during infancy, adolescence, and older age. Some physicians theorize that periods of major hormonal change may lead to the condition. However, prepubertal gynecomastia is relatively rare due to lower circulating hormone levels. Some scientists suspect that boys in this range may be more susceptible to hormonal changes and disrupting chemicals, which may lead to gynecomastia.
Is direct skin exposure the main link to male gynecomastia or can smelling or inhaling essential oils, as in aromatherapy, be linked, too?
The clinical cases have only described using essential oils on skin or topical exposure and not aromatherapy. In the NIEHS study, the team described whether topical exposure to the chemicals led to hormonal activity. Further studies are needed to determine if the same can be said about aromatherapy.
Are girls affected by lavender and tea tree oils?
Because breast growth is a natural process for pubescent girls, it is more difficult to determine whether pure essential lavender oil or tea tree oil have the same effect in females as males. A clinical case was reported in 2019 (https://pubmed.ncbi.nlm.nih.gov/31393563/
