For an exotic smelling oil...try Sandalwood, YlangYlang, Patchouli, Nutmeg and Benzoin...equal parts each except the nutmeg which can be overpowering. I usually just use a drop of that.
Here's a good headache oil...Lavendar, Eucalyptus, Rosemary, and Peppermint. Smells good. Kinda medicinal. Relieves sinus congestion, headaches, tension.
Patchouli/Orange. Sensual, aphrodisiac, sedating.
Be sure to mix these with a base oil if you are going to use them on the skin. The headache oil can be massaged around the sinus area, temples, back of the neck and base of the skull. It is also good for a bath oil.
I've got tons and tons of recipes. Let me know specifically what you are looking for. I'm happy to share!
