Thyme has a warm and pungent, green and inviting aroma. Be careful when putting it on the skin as it can be irritating.

Thyme is one of the most energetically hot and invigorating of essential oils. It is a powerful tonic of the body's yang energy... Strongly antibacterial, the essential oil is indicated for a number of infections.--from Aromatherapy for Healing the Spirit, page 122.
