Don’t take our word for it. Here’s every fact on this site, with its evidence grade, its caveats, and a link to the source, so you can check us.
We start you on the strong ones: findings that have been replicated or come from one large, well-controlled study. Moderate and weak facts are here too, labeled for what they are. Use “Link to this fact” to share a single card.
Green, natural and unscented / Self-reported survey
'Natural' essential oils have not been shown safe for hormone-sensitive children: the only survey claiming so had about a 5% chance of detecting even a tripling of risk.
Moderate evidence: Power figure is evidence base arithmetic from the paper's group sizes and observed baseline; absence of proof of safety is not proof of harm.

Green, natural and unscented / Review of other studies
Even a review that found little evidence of harm from lavender and tea tree oil in children warned that 'a lack of evidence of harm cannot be interpreted as evidence of safety' for essential oils in children's products.
Moderate evidence: Direct quote; the review's own conclusion is that the link is unsupported.
