Which essential oils are toxic to humans?

While some essential oils may be safe for topical use, there are certain oils that are considered toxic when ingested or used in aromatherapy. These include camphor, eucalyptus, pennyroyal, wintergreen, and sage. In addition, many essential oils can cause skin irritation or allergic reactions, so be sure to do a patch test before using any essential oils topically.

How much essential oil is toxic to humans?

The amount of essential oil that is considered toxic to humans depends on the type of oil, its concentration, and the duration and route of exposure. Generally, essential oils must be used in very small amounts due to their high potency. For example, ingesting as little as one drop of certain essential oils can be toxic. When using essential oils, it is important to always dilute them with a carrier oil and to follow the manufacturer’s instructions for safe use.
