Fragrance

I found an amazing historical fact on cologne. I thought cologne was just for fragrance; I never thought it was used for medicine or the like. Read the fact below. The link is there in case you really wanted to know more of the subject matter.

eau de Cologne , dilute perfume [commonly called cologne in English] introduced c.1709 in Cologne, Germany, by Jean Marie Farina. It was probably a modification of a popular formula made before 1700 by Paul Feminis, an Italian in Cologne, and was based on bergamot and other citrus oils. The water of Cologne was believed to have the power to ward off bubonic plague .

Now I feel more like in a force field when using my cologne. I feel like being protected. I think the next thing I want to know if the the smell has something to do with cleanliness or is it just an effect of cleanliness. Will a fragrant odor drive off germs or is the fragrant odor just an effect of a clean air. Things like that.
