oh yes esssential oils are lovely, and different oils have different properties - calming, anti inflammatory, stimulating, astringent, antibacterial etc - lavender is one of the few that is safe to use undiluted. there are so many lovely oils which you can also blend to make your own mixes, and there are so many ways to use them; in oil burners, diffusers, inhalations, in the bath, mouthwashes, oils in different carriers for massage, perfumes, room sprays. there are loads of different carrier oils which can also be used on their own. sesame oil is grounding and you can massage it in, before a soak in the bath. you can also make your own oils by Infusing plants/flowers eg. calendula, rose. I love all this stuff and like making my own things. they also form the oil part of making creams and balms. it's something I enjoy doing when I'm well!
