Glycyrrhizin is the main sweet-tasting compound from liquorice root. It is 30 to 50 times as sweet as sucrose. Chemically, glycyrrhizin is a triterpenoid saponin glycoside of glycyrrhizic acid. Upon hydrolysis, the glycoside loses its sweet taste and is converted to the aglycone glycyrrhetinic acid plus two molecules of glucuronic acid. Although sweet, the taste sensation of glycyrrhizin is different from that of sugar. The sweetness of glycyrrhizin has a slower onset than sugar, and lingers in the mouth for some time. Unlike the artificial sweetener aspartame, glycyrrhizin maintains its sweetness under heating. Glycyrrhizin is used as a flavoring in some candies, pharmaceuticals, and tobacco products.

Indomethacin is a non-steroidal anti-inflammatory agent (NSAID) that inhibits the enzyme cyclooxygenase necessary for the formation of prostaglandins and other autacoids. It also inhibits the motility of polymorphonuclear leukocytes.Antiinflammatory effects of Indomethacin are believed to be due to inhibition of cylooxygenase in platelets which leads to the blockage of prostaglandin synthesis. Antipyretic effects may be due to action on the hypothalamus, resulting in an increased peripheral blood flow, vasodilation, and subsequent heat dissipation.The following symptoms may be observed following overdosage: nausea, vomiting, intense headache, dizziness, mental confusion, disorientation, or lethargy. There have been reports of paresthesias, numbness, and convulsions.
