[ 22 ] Rufus of Ephesus ( fl . 98–117 AD), a physician famous for his work on the variations of the pulse, described the symptoms of diabetes as "incessant thirst" and immediate urination after drinking, which he ...
Nitroglycerin (NG) (alternative spelling of nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
William Murrell (1853–1912) was an English physician, clinical pharmacologist, and toxicologist. Murrell is best known for being one of the first to recognize the clinical benefits of glyceryl trinitrate (also known as nitroglycerin) for the management of patients with angina pectoris.
The Middle Ages contributed a great deal to medical knowledge. This period contained progress in surgery, medical chemistry, dissection, and practical medicine. The Middle Ages laid the ground work for later, more significant discoveries. There was a slow but constant progression in the way that medicine was studied and practiced.

Nitroglycerin was written about as early as 1846 [5] [6] and came into medical use in 1878. [7] [8] [9] The drug nitroglycerin is a dilute form of the same chemical used as the explosive, nitroglycerin. [9] Dilution makes it non-explosive. [9]
The maximum shelf life of nitroglycerin-based dynamite is recommended as one year from the date of manufacture under good storage conditions. [7] Over time, regardless of the sorbent used, sticks of dynamite will "weep" or "sweat" nitroglycerin, which can then pool in the bottom of the box or storage area.
The advances made in the Middle East in botany and chemistry led medicine in medieval Islam substantially to develop pharmacology. Muhammad ibn Zakarīya Rāzi (Rhazes) (865–915), for instance, acted to promote the medical uses of chemical compounds.
