Definitely worth a read! While many people have great experiences with essential oils, precautions on how to use them aren’t shared enough.
Very high concentrations of plant oils should be used carefully. I began college studying horticulture because of my background in gardening / herbal remedies and went onto complete three years of molecular plant biology lab work at one of the foremost universities in horticulture and agriculture. If there’s one thing I’ve learned, it’s that there’s an enormous diversity of plants and most haven’t been completely researched yet. Just because it’s natural doesn’t mean it’s safe. Oils are powerful and absorb easily into the skin. Too much of a good thing can be bad. Dilute, dilute, dilute.
