Ways to practice aromatherapy
Common methods include:
- Indirect inhalation: You can add the oil to room diffusers or apply a few drops on a tissue, pillowcase, or piece of clothing. Other options include aromatherapy candles, room fresheners, or wearing an aromatherapy bracelet or pendant.
- Direct inhalation: There is anecdotal use of individual vaporizer masks to inhale essential oils directly. Other options include a nasal stick or breathing the oil from the steam from a water bowl.
- Absorption through the skin: Dilute essential oils for massage, in bath salts, lotions, water therapies, soaps, shampoos, and detergents.
For massage, dilute 12–18 drops in 1 ounce of massage oil or lotion, according to the Alliance of International Aromatherapists (AIA), an aromatherapy advocacy group.

Precautions with aromatherapy
When using essential oils, be sure to read the labels and use this guidance:
- Use pure essential oil: Buy essential oils that state they are a “pure essential oil.” They are often sold in dark amber bottles. Pure essential oils are more expensive than diluted oils, have a more intense smell, and disappear rapidly when placed on paper. Avoid essential oil products that state on the label they are “perfumed” or “fragranced.”
- Dilute oils when necessary: If oils are not diluted, they can irritate and damage your skin. Do not apply diluted essential oils to broken or irritated skin. Dilute 12–18 drops in 1 ounce of massage oil or lotion for adults with no health issues. Use about 6 drops in 1 ounce for:
- children 6 years and older
- pregnant people
- older adults
- skin care
- Use safely: Take into consideration the best way to use the essential oil. For instance, if you are in a small room, you may need less oil. In general, you should not eat or drink any essential oils. How you use them will depend on the oil you are using and what you are using it for.
- Consider age: If using essential oils on a child, use a smaller amount and dilute the oil more than you would for an adult. Some oils are not suitable for infants and children.
- Store safely: Keep essential oils out of sight and reach of children. Store oils in their original bottle.
Always read the instructions before using an essential oil. If pregnant or breastfeeding or chestfeeding, seek advice from a qualified health professional before using.
