Yes, I know about Dave's Insanity Special Reserve. My sister gave a bottle to her hubby for Christmas a couple years ago. Comes in it's own wooden case, packed in straw. The label says "Do not use around pets or small children."
The directions expressly state that you are NEVER to use more than ONE DROP at a time.
The last is a very good suggestion. A drop will heat up a bowl of chili very nicely.
