I've said it once and I'll say it again: artificial fragrance is one of the most significant sources of toxins and hormone disrupting chemicals. Home fragrance is a major culprit here. Whether you are lighting your favorite BBW candle or plug-in scent, you are introducing toxins into your home that you are continuously exposed to.
Your best bet is avoiding these all together - but if you're like me and can't resist having candles at home, here are the best non-toxic options I could find. You want candles that are either made from soy, beeswax, or a blend of both, and use cotton or wooden wicks. No artificial fragrance, no phthalates, and no petro soot.
