Ummmm, no. Nitroglycerin (also called glyceryl trinitrate) is a powerful
explosive and an important ingredient of most forms of dynamite. However, is
also used with nitrocellulose in some propellants, especially for rockets
and missiles, and it is employed as a vasodilator in the easing of cardiac
pain. It does this because it dilates blood vessels by relaxing the smooth
muscles surrounding them, thereby increasing blood flow. The formulation of
the explosive and the heart medication is the same, just the concentration
is different. Medical nitroglycerin is simply diluted to make it
nonexplosive. In the mid 1800's people who handled pure nitroglycerin
reported their faces would get flushed and their heart would pound. That is
how William Murrell of Westminster Hospital in London knew to look to
diluted nitroglycerin as a long lasting remedy for angina. In fact most
chemicals used for medicine are the same chemicals used for other purposes.
