I did a nice bath with baking soda and epsom salts- 4 drops each cinnamon leaf, lavender, and ylang ylang EO (based on one of my books that says this is a good bug bite mixture). My cinnamon leaf is probably very degraded by now because it's several years old and has been living through a bad variety of temperature changes.
For direct application, I made a mix- 10 droppers of vodka, 12 drops lavender, 10 lang ylang, 3 cinnamon leaf. To be applied by q-tip. This isn't really a perfume, no real base note. All I want is not to itch!
