Estrogens in Plastic Labware

The safety of essential oils in puberty, and hormonal effects in general, are important health concerns. In a 2007 research report by Colorado and North Carolina doctors and scientists, in vitro evidence seemed to support the notion that lavender oil and tea tree oil were responsible for breast growth in three young boys, suggesting an [...] [...]

Tea tree oil quality and constituents

I am writing this in response to a recent discussion on various facebook pages about tea tree oil (TTO), and whether a TTO with 51% terpinen-4-ol would be better than one with 41%, or whether 51% suggested adultration. Most TTO is produced in Australia and China, and this article is about the quality of Australian [...] [...]

Lemon on the rocks: keep your essential oils cool

Essential oils are happiest when cold. If you keep them refrigerated they will last twice as long, especially if you live in a warm climate. Essential oils are expensive, so you want them to stay active as long as possible! Cold good, oxidation bad With time, most essential oil constituents oxidize, and heat promotes oxidation. [...] [...]

Essential oils and eye safety

There has been much social media discussion recently (February 2012) about the wisdom or otherwise of putting essential oils into your eyes to treat eye problems. This arose from two webpages, here and here. One of these, on the Livestrong website, states: “More and more people are choosing to use alternative medicines to treat minor illnesses [...] [...]

Diaper rash safety

Robert, Hello there. I am in hopes you can please help me. I currently use the doTERRA line of essential oils and I also have used them to help my 18month old daughter. I have recently used ylang-ylang, roman chamomile, lavender and sandalwood to reduce stress and attempt to balance my hormones that have been [...] [...]

Lavender oil is not estrogenic

Lavender oil does not mimic estrogen nor does it enhance the body’s own estrogens. It is therefore not a ‘hormone disruptor’, cannot cause breast growth in young boys (or girls of any age), and is safe to use by anyone at risk for estrogen-dependent cancer. The lack of estrogenic action is the conclusion of a [...] [...]

Can essential oils & antibiotics be used together?

Hi Robert, My husband has just been diagnosed with endocarditis. His doctor wants to start him on intravenous antibiotics followed by oral doses of antibiotics. I was hoping to support him with essential oils. Do you think that’s safe, or could they interfere with the effectiveness of the antibiotics? I would appreciate your advice. Karin [...] [...]

Hygienic massage with essential oils

Human skin carries some 900 species of bacteria, and when one person massages another, a two-way microbial exchange takes place. I’m not suggesting that there is significant risk here, and shaking hands with another person is no less risky. But, thorough hand-washing before and after a massage session is recommended. In a hospital environment, infection [...] [...]

Ingredient obsession

I am not against transparency in labeling. I think it’s a subject that could use a lot of discussion. But I am against ingredient obsession. In a society that allows alcohol, tobacco and firearms to be freely purchased, and that turns a blind eye to the widespread use of illegal drugs, why are we concerned [...] [...]

Wintergreen oil safety

Hello Robert, I’d like to ask your opinion if I may. Recently I’ve had a western herbologist join my business and I am finding discussions with him to be very enlightening as well as confusing in a way. For instance, we were talking about wintergreen and how it is contraindicated in Aromatherapy because of its [...] [...]
