Here’s handy info from Gretchen Lidicker at Mind Body Green, with info on which essential oils to avoid in the bath. Says Gretchen;
“Before you go dropping random oils into your tub, there’s something important to note: Not all essential oils are right for the bathtub. Some of them can irritate your skin, eyes, and other sensitive regions, big time. So I spoke to Mariza Snyder, D.C.—functional medicine expert and author of the upcoming book The Essential Oils Hormone Solution (as well as a few other books on the topic) to figure out what the proper bathtime protocol is.
One well-known way to avoid irritating the skin with essential oils is to use a carrier oil, like coconut oil or jojoba oil. But is it the same for the bath? According to Dr. Snyder, it’s not quite as simple as diluting your essential oil. “You never want to simply drop essential oils into your bathwater by themselves or they will potentially irritate the skin. That said, you do not always need to use a carrier oil when adding essential oils to your bath. You can also use Epsom salts and Castile soap to protect your skin and disperse essential oils throughout the bathwater.”
There are also certain essential oils you shouldn’t be adding to your bath even with a carrier oil.
Which Essential oils don’t go in the bath, and which are OK?
Are you ready for the bad news? There’s a pretty long list of oils that should never find their way into your bathtub, according to Dr. Snyder, such as:
Cinnamon and cinnamon bark
Luckily, there’s an even longer list of essential oils that are great for bath time, such as:
Gretchen’s Bath Recipe
Add about 1 to 2 cups of Epsom salts along with 1 tablespoon of your carrier oil (you can use coconut, jojoba, or sweet almond, among others) or soap to a tub of warm water before adding no more than 3 to 6 drops of essential oils & swirling the bathwater before you jump in. Then, soak for about 20 minutes, and, of course, don’t forget to breathe in slowly through your nose to savor the smell of whatever oil you chose. Enjoy!
