Most endoscopy (colonoscopy and EGD) is done with conscious sedation; generally with an amnesia drug (Versed) and some painkiller. You are actually quite awake, but the Versed blunts or eliminates your memory of the procedure. Propofol produces deeper sedation, requires an anesthesia person and usually costs more.
Sage is also used internally in the treatment of night sweats, excessive salivation (as in Parkinson's disease), profuse perspiration (as in TB), anxiety and depression. Externally, it is used to treat insect bites, skin, throat, mouth and gum infections and vaginal discharge.
The primary medicinal components in sage are volatile oils, flavonoids, and rosmarinic acid. Some of the distinct effects of sage that have been reported include anhidrotic (prevents perspiration); blood sugar-lowering effects in diabetics; antimicrobial; and drying up the flow of milk during lactation.
