Nitroglycerin was once used as an explosive. It was so unstable, and sensitive to heat and shock, that its use as a pure material for blasting was eliminated in the 19th century. Since 1866 when Alfred Nobel discovered that nitroglycerine retains its explosive power while loosing its "touchy" nature when mixed with sawdust or diatomaceous earth, nitroglycerin is the explosive agent ingredient in dynamite. Nitroglycerin is also a medication used to treat chest pain associated with restricted blood flow to the heart. In this application it is a "pill" dissolved under the tongue.
