Side Effects Of Lavender Oil

Lavender oil has many benefits including a proven effect on reducing anxiety, stress and migraines, as well as an analgesic effect for pain relief. But used incorrectly and any essential oil is dangerous. In this article we look at the side effects of lavender oil.

With care, essential oil has an extremely low incidence of any side effects whatsoever, but it is always worth knowing – just in case something goes wrong.

“Lavender oil is an essential oil obtained by distillation from the flower spikes of certain species of lavender” (Wikipedia). 

As perhaps one of the most used of the essential oils, there is considerable proof around the potential benefits of using lavender oil.

However, if you decide that lavender oil sounds like something that could help you, then it is worth remembering that ALL essential oils can be dangerous in their pure form.

When it comes to using lavender oil, a carrier oil or similar compound is needed to avoid skin/ internal reaction to the concentration of a pure essential oil.

When used with a carrier or dispensed via a diffuser, lavender oil is generally a very safe form of medicine. Particular care should always be taken however, when ingesting any form of oil and you should always consult your family doctor before starting a new treatment regime.

We cover below some of the more common side effects of lavender oil. However, it should be pointed out that these are all quite rare and, in comparison to some common medications, essential oils are very safe to use (if used correctly)
