Start Here

Call Me Oil is for people who already have a bottle of essential oil in hand, or are about to buy one, and want to use it well. Most readers arrive with one specific job in mind. You might be diluting tea tree oil for a spot on your skin, easing a stuffy nose, scenting a room, mixing a roller blend or deciding whether a brand is worth the price. This page shows you where those answers live and how we approach them.

Start with safety, every time

Before any recipe or benefit, check the safety limits that apply to you. Most essential oils need to be diluted in a carrier oil before they touch skin. A few, such as cold-pressed bergamot and expressed lime, can cause burns or dark patches when skin they have touched is exposed to sunlight. Swallowing essential oils, using them during pregnancy, and using them around babies, children, cats and dogs all carry extra risks, and our guides spell those out before anything else. If someone has swallowed an essential oil or is having trouble breathing, call Poison Control at 1-800-222-1222 or 911 instead of searching for an answer online. If a pet may have been exposed, call your veterinarian right away.

How the site is organized

The site has four sections, and each one builds on the one before it.

Basics

Basics is the foundation. It covers what essential oils are and how they are made, how they differ from fragrance oils, which carrier oils to use, how to dilute, how long oils last, how to run a diffuser, which oils are risky for pets, and profiles of single oils from lavender to vetiver. If you are new, read this section first, because every other section assumes you know how to dilute.

Wellness

Wellness covers aromatherapy for sleep, stress, mood and focus, along with headaches and pain, colds and congestion, digestion and oral health. Each guide compares popular claims with the published research and says plainly when a symptom calls for a doctor instead of an oil.

Blends

Blends is the recipe section. It explains how to combine oils by top, middle and base notes, then puts that theory to work in diffuser blends, roller bottles, room and linen sprays, natural cleaning, bug repellents, perfume and cologne, and scented bath and body products.

Brands

Brands helps you buy essential oils in the United States. It covers brand reviews, head-to-head comparisons, product roundups, purity and organic labels, and the warning signs of oils that are diluted or mislabeled.

How to read our numbers

Our recipes give exact drop counts and percentages, because a vague few drops is how people end up with irritated skin. As a working rule, one milliliter holds roughly 20 drops. That makes a 1 percent dilution about 6 drops of essential oil in 1 ounce (30 milliliters) of carrier oil, and a 2 percent dilution about 12 drops. Dropper sizes vary between brands, so treat drop counts as close estimates and start at the low end.

What our reviews are and are not

Our brand reviews and roundups are research-based. We read manufacturer information, published test reports such as GC/MS results where brands share them, label and sourcing details, and patterns in owner reports. We do not run our own laboratory tests, and every review says how it was researched. There are no affiliate links, ads or sponsors on the site, and the Disclosure page explains the details.

Where to go next

New guides are being added to each section, so the section pages are the best place to see what has been published. To learn who writes here and how the work gets done, read About. If you have a question we have not answered yet, or a brand you would like us to research, use the Contact page.
