Essential Oils to Avoid

Unsafe Oils for Aromatherapy

The following is a list of essential oils that should be avoided for aromatherapy use. Although you may find these essential oils are available in stores or online, that should not be taken as an indication of them being safe.

This is not an exhaustive list. You are encouraged to seek the guidance of your doctor and/or a reputable and experienced aromatherapist before using any essential oil. Depending on your health, age, and other factors, an oil that is suitable for one person may be dangerous to you.

Note that just because a particular essential oil doesn’t show up in this listing is not an indication that it is okay for your use. Again, seek professional advice for guidance.
