Don’t just take an oil brand’s word for it. Here’s what holds up when I look at the chemistry behind the bottle, so you know an oil comes from the plant it names and carries the compounds it should, not just a scent and a promise.
As a plant biologist with a background in plant biochemistry, I judge an essential oil by what it actually is, the volatile compounds a plant produces, drawn from a named botanical source and extracted in a way that keeps them intact. My training is in exactly these compounds, the terpenes and aromatics that make an oil work, so I can tell a clearly sourced, single-species oil from a vague blend that leans on its label.
I also check what the science says against reliable sources before I recommend anything, rather than repeating a brand’s marketing. Every brand below earns its place the same way: a real, named plant behind the oil, plus the catch you should know before you buy.
