I was introduced to Atom Balm (or something similar) freshman year on my high school cross country team. The coach offered it up to us on the first cold-weather practice day. I still remember that first post-run shower...(Yikes!)

I love that toasty feeling when riding in the cold. I ride year-round down to 10F, and I have found I "loosen-up" on my own after about 10 minutes of riding, but then, I tend to run hot. As far as morning stiffness I replaced my coffee in-take with Yerba Mate a few months ago. It has similar caffeine content, but far less acidity than coffee or tea. It turns out to have anti-inflammatory and anti-histamine properties. At 56, I now have far less leg and back stiffness in the morning than I have for the past few years.

However, it smells like wet grass, whereas the clove-mint fragrance of your embrocation cream sounds delightful.
