Parents of children ages 2 to 15 years old will provide data using the APICHS.
Other: No Intervention
There is no intervention; observation only.

Primary Outcome Measures :
  1. Lifetime prevalence of prepubertal gynecomastia [ Time Frame: Baseline ]
    The number of participants who were exposed to lavender and tea tree essential oils and had ever experienced prepubertal gynecomastia

  2. Lifetime prevalence of precocious puberty [ Time Frame: Baseline ]
    The number of participants who were exposed to lavender and tea tree essential oils and experienced prepubertal gynecomastia

  3. Endocrine Disruption - Comparison between exposed and unexposed [ Time Frame: Baseline ]
    The difference in rates of endocrine disorders between children who were exposed to lavender or tea tree essential oil and those who were not. Exposure is measured using the Aromatic Plant Ingredient and Child Health Survey (APICHS), which measures total exposure, providing a continuous variable ranging from 0 to unlimited exposures, and a dichotomous yes/no exposure outcome variable.
