Walk into any wellness shop and there are forty bottles on the wall. You need three. Lavender, tea tree, peppermint. Between them they cover sleep, skin and head-clearing, which is most of what people actually buy essential oils for.
Lavender
The evening bottle. Two drops in a diffuser half an hour before bed, or one drop on the corner of a pillowcase. It is also the gentlest of the three on skin, which makes it the one to use if you're diluting anything.
Tea tree
The first-aid bottle. Diluted, it's a reasonable choice for spots, small nicks and fungal nuisances like athlete's foot. It has genuine antibacterial and antifungal activity behind it. It is also the one people most often misuse neat — don't.
Peppermint
The daytime bottle. Blocked head, dull afternoon, tension across the forehead. Diluted and rubbed into the temples, it has a long history for exactly that.
How to dilute, without maths
The whole rule fits in one line: 2 drops of essential oil per teaspoon of carrier oil for adults, on ordinary skin. That's roughly a 2% dilution. Halve it for the face, halve it again for anyone elderly or frail, and don't use it at all on babies. Carrier oil means any plain vegetable oil — olive, sweet almond, jojoba, fractionated coconut. The kitchen bottle is fine.
What you can skip
Ingesting oils. A drop of oregano oil in water is not a mild thing; essential oils are concentrated to the point where a few millilitres is a large dose of plant compounds. Leave internal use to people qualified to supervise it.
"Therapeutic grade." It's a marketing phrase, not a regulated standard. What matters is that the bottle names the botanical (Lavandula angustifolia, not "lavender fragrance"), is dark glass, and shows a country of origin and batch or expiry date.
Buying fifteen bottles at once. Oils oxidise. A bottle you use twice a year is mostly wasted money, especially citrus oils, which turn within a year or so of opening.
Try this today: do the patch test you've been skipping. One drop of lavender in a teaspoon of olive oil, dabbed on your inner forearm, left overnight. If nothing happens, that's your dilution for everything else.
