Here's a recipe for something you shouldn't eat. You will have to look around special for most of these ingredients. It's even a little bit of a pain in the butt to get ethyl alcohol, but it does a pretty good job of mixing with the essential oils. I can tell you that water doesn't work. Vodka does work, but it gets expensive and you could use that stuff for... something else.

• 200mL ethyl alcohol or vodka
• 10 drops patchouli oil, Wyndmere brand
• 5 drops cedar oil, Wyndmere brand
• 20 drops bergamot oil, Wyndmere brand

Mix in an atomizer and shake well. For a more potent cologne that lingers on your shirt all day long, use only 100mL of ethyl alcohol/vodka.

I have no loyalty to Wyndmere; I just happen to have a lot of it. I am not convinced oils from different brands can be used evenly, so that's why I qualified what I was using.

Patchouli is a pretty standard perfume scent and it can go for both sexes. It's really potent; the recipe below is trying to balance patchouli and bergamot, and it takes roughly 2x bergamot to balance it out. Bergamot oil comes from Bergamot oranges, a kind of bitter/sour orange. You can get an idea of what it is from Earl Grey tea. It's a more complex flavor than sweet oranges, and gives the cologne a good citrus scent.

The cedar oil is just to get a touch of cedar mixed in. Too much reminds me of hamster bedding. If you cut it back a little and blend it in with patchouli or another type of wood-based oil, you can get something like fresh mulch instead. Cedar tends to wake me up so I think it's good for a morning cologne.
