There is an immense amount of studies exploring the concerns that essential oils are highly concentrated and can irritate the skin when used in undiluted form. Therefore, they are normally diluted with a carrier oil for topical application, such as jojoba oil, olive oil, or coconut oil. Phototoxic reactions may occur with citrus peel oils such as lemon or lime. Also, many essential oils have chemical components that are sensitisers (meaning that they will, after a number of uses, cause reactions on the skin, and more so in the rest of the body). Chemical composition of essential oils could be affected by herbicides if the original plants are cultivated versus wild-harvested. Some oils can be toxic to some domestic animals, with cats being particularly prone.
With neuroprotective effects and cognitive performance boosting abilities, essential oil benefits have helped many people who are suffering from neurodegenerative diseases like Alzheimer’s and dementia.

Peppermint can help relieve headaches, curb appetite, settle an upset tummy and is great for an afternoon pick me up.
According to a systemic review and meta-analysis published in Pain Research and Treatment, there is a significant positive effect of aromatherapy, compared to placebos or control treatments, in reducing pain.

There are three different categories of oils: top notes, middle notes and base notes. Generally, top notes are more stimulating, uplifting and refreshing and base notes are more sedating and relaxing, though this is not always the case. Whilst not always strictly accurate, another good general guide to this is that citrus oils (Lemon, Lime etc) can often be top notes, uplifting and stimulating, whereas floral oils (Lavender, Jasmine, Ylang-Ylang, Rose etc) are more middle to base notes and more relaxing.
