This is what we have found worth reading on essential oils. Some of it is enthusiastic, some of it is sceptical, and the sceptical pieces are here on purpose.
Start here
Johns Hopkins Medicine — Aromatherapy: Do Essential Oils Really Work?
A teaching hospital's own assessment, and a measured one. It is willing to say where the evidence stops, which is rarer in this category than it should be. If you read one thing on this page, read this.
What the laboratory work shows
Scientific Reports — The antibacterial and antifungal activity of six essential oils
Peer-reviewed laboratory work on how six oils behave against bacteria and fungi in controlled conditions. The distinction that matters is one the paper draws itself: activity in a dish is not activity in a room.
On using oils safely
DermNet — Allergic contact dermatitis to essential oils
A dermatology reference on why undiluted oils on skin can cause a reaction, and why patch testing is standard practice. Clear, specific, and the right place to read about it.
Moreland OB-GYN — Essential oils and pregnancy safety
Included for what it advises avoiding rather than what it recommends. If you are pregnant, this is a conversation for your doctor.
Where oils are commonly used
These describe the areas people most often apply essential oils to — a map of the category rather than a set of recommendations.
Healthline — Essential oils and muscle massage
A consumer-health overview of which oils turn up most often in massage and bodywork traditions, and what is actually known about them.
GoodRx — Oils used in massage and movement recovery
Pharmacist-reviewed, and more conservative than most writing in this category. A good counterweight to wellness blogs.
WebMD — Oils studied as insect repellents
Covers which plant oils have been studied for repelling insects, and how they compare with conventional repellents. Repellency is regulated as its own category, separate from cosmetics, which is part of why you rarely see it discussed this plainly.
American Sinus Institute — Essential oils and sinus congestion
Written by a clinic, and it reads like it. Included because steam inhalation is one of the oldest household uses of eucalyptus and it would be odd to pretend otherwise. One clinic's view, clearly stated.
Association of Migraine Disorders — Essential oils and migraine
A patient advocacy organisation summarising what has and has not been studied. Notably more cautious than most commercial writing on the same subject.
A note on how to read all of this
Essential oils attract confident writing in both directions — miracle claims on one side, flat dismissal on the other. The honest position is narrower than either: some oils have been studied more than others, most studies are small, and laboratory results do not automatically transfer to a home.
That narrowness is the interesting part. It is also why this page exists.
