It's not a drug and is probably able to probably fall under a vague ingredient description due to being plant based.

A quick look at the ADM brochure shows they call it "A potent, natural, plant-derived ingredient shown to dissipate body heat by facilitating blood flow to the body surface band enhancing thermoregulation." This basically narrows it down to one of two things and the smell of the mineral should give it away. One should smell like a Mexican spice cabinet and the other similar to a cured forage. They could even be mixed together, but "potent" makes me believe it's one over the other.

The minute you walk into a shed full of Vitafirm's Heat mineral gives you an obvious whiff of what they use. Haven't used ADM's mineral to know what it smells or tastes like.
