The Best Essential Oils You Can Buy On Amazon

One of the best parts about shopping on Amazon is the insane selection, and searching for "essential oils" on the mega-site will return more than 100,000 results. But that also means a wide range in quality, especially because the way in which essential oils are made greatly affects their potency and purity. If your goal is to buy essential oil on Amazon without sacrificing quality, keep scrolling for expert tips and product recommendations that are worth your money.

There are quite a few factors to keep in mind to figure out whether you're looking at a quality essential oil. Serena Goldstein, N.D., recommends doing your research on a company's own website before pulling the trigger on a purchase. It's a good sign when a company is forthcoming about where their materials come from and have independent studies conducted on their oils. Make sure the ingredient list only includes the oil itself and maybe a carrier oil, she says. And she cautions against third-party sellers on Amazon: "If something is significantly cheaper and it's through a third party, sometimes people might not always get exactly what they paid for," she says. Some sellers of essential oils have been known to add synthetic materials, vegetable oils, or cheaper, similar-smelling essential oils, without revealing the additives on their labels.

You should also look for the Latin name of the plant that you're buying on the bottle, says Ariana Lutzi, N.D., nutrition consultant for BUBS Naturals. If a price seems too good to be true, it probably is. "If one essential oil is $5 and then another one is $70, the cheaper is most likely going to be a poor product that's been diluted or not made with the plant part or piece that it claims," says Lutzi. Country of origin is also worth looking into, as oils from China and India have been known to be more contaminated with heavy metals, she notes. Look for wild-crafted or farm-harvested so you know that it wasn't just made from a batch of herbs bought online. Lutzi recommends going with wild-crafted when possible, but if you choose farm-harvested, double check that the plants weren't sprayed with pesticides.

"That means that it's a higher quality oil because they did spectrometry on it to identify the levels of actual active oil constituents."
