THE CAUSES OF ESTROGEN DOMINANCE
Strictly speaking, it's possible that we are all -- men, women and children -- suffering a little from estrogen dominance, because there is so much of it in our environment. You would have to virtually live in a bubble to escape the excess estrogens we're exposed to through pesticides, plastics, industrial waste products, car exhaust, meat, soaps and much of the carpeting, furniture and paneling that we live with indoors every day. You may have on-and-off sinus problems, headaches, dry eyes, asthma or cold hands and feet for example, and not know to attribute them to your exposure to xenohormones. Over time the exposure will cause more chronic problems such as arthritis and premenopause symptoms, and may be a direct or indirect cause of cancer.
This is part of an article regarding the effects of estrogen dominance in our bodies. What has this got to do with homemade soap? Well after some research and going through premenopause myself I have read that lavender and tea tree oil both mimic estrogen. So while I will still make lavender and tea tree soaps just know even good things can be over done. Don't just take my word for it, educate yourself.
