A new piece of news came out last week that Prince Harry and Meghan Markle chose a vegan paint and the wall infused with eucalyptus and rosemary! My first reaction was, wow, the essential oil infused wall! What a creative idea! It would be wonderful if you could always feel the subtle aroma in the room without taking a hassle of burning a candle, or putting water into the diffuser and turning on the device.
However, the more you think about, the less you get excited about this great seeming idea. The biggest concern is that the essential oil are extremely concentrated with various chemical properties. Therefore, the quantity and the method to enjoy the essential oils has to be wisely and carefully selected for the specific purpose, for specific users.
When the user includes infants, a greater caution is required. Newborns' metabolism capability is much weaker than those of adults, and the newnatal skins do not fully develop until the 3 month old. Therefore, it is advised by the essential oil expert, Robert Tisserand, to use the hydrofoils instead of essential oils, or with the highly diffused carrier medium for babies. Where will the oil infused wall fall into? Not sure.
Furthermore, the choice of the oils can be a concern. Neither eucalyptus or rosemary is included in the list of safe oils for babies. In fact, eucalyptus is a controversy oil for its chemical component called 1.8 cineole. While it offers a wide range of strong therapeutic properties, it is considered that too much of it can act negatively on the temperature receptors of children's lungs and cause slowed breathing. Among eucalyptus spices, the most common type with the botanical name, Eucalyptus globules, has a intensified character of 1.8 cineole compared with the one called Narrow Leaf Eucalyptus (Eucalyptus radiata). So, the kind of the oil also matters.
All in all, I came to conclude that the essential oil does not have to be infused in the wall. As the baby grows, as the season turns, or as your mood changes, you can switch the oils in the diffuser or candles.
