The difference between a vial of oil and sprig of plant are, of course, one of concentration. Henley et al. (2007) [1] is the lavender, tea tree oil as an estrogen mimic study that everyone goes to, and there have a been a few papers in the interim but none with exactly the same focus. The hepatotoxicity of Lavender is usually associated with coumarin and is more hand waving than anything else. A vial of oil is obviously different than a sprig of plant. And a soap, or cream is obviously different than both a plant or vial of oil. But all of the above listed contain the suspect oils. It doesn't seem like a good idea to hotbox baby clothes with endocrine system disrupting allergens, even at low concentrations.
