The purpose of this study is to explore the potential for an association between the development of prepubertal gynecomastia and history exposure to lavender essential oil, tea tree essential oil, and other essential oils.
After being informed about the study and privacy, parents will give informed consent and complete the APICHS (Aromatic Plant Ingredient \& Child Health Survey), a validated measurement tool for determining exposure to plant-based ingredients in pediatric personal care products.
