First up, Qoleum. This stuff goes out of its way to say it's vegan. That's pretty sweet. Qoleum comes in three flavors: low, medium, and hot. I'm enough of an embrocation fiend to have all three, but medium and hot would probably do you right.
Here's the sales pitch:
"Made from 100% natural vegan base for pre-sports levels of warming applications. Contains capsicum, menthol, eucalyptus and vitamin E.
100% organic, made with the finest ingredients in Belgium"
Vegan, organic, and Belgian, what more could you ask for?

When I started racing 'cross more seriously, I bought myself some Sportsbalm embrocation. Three years later, I still have the same two tubes of Sportsbalm (The Dutch site). I like Sportsbalm. It lasts a while (both on your legs and in the tube). The medium is just right for cooler and damp days, while the XXX will get you through most cold and/or crappy rainy days. It lacks the feel good organic ingredients and explicit vegan tag, but it works well and the ingredients are vegan friendly.
Medium ingredients: Mineral Oil, Petrolatum, Tea Tree Oil, Wintergreen, Cayenne, Paprika Oil, Nutmeg Oil.
Hot ingredients: Mineral Oil, Petrolatum, Cajeput Oil, Wintergreen, Cayenne, Paprika Oil, Nutmeg Oil.
So, not organic, but it's vegan and Dutch. That's two out of three.
