(The British Herbal Pharmacopoeia.)
Aqueous and methanolic extracts of the rhizome, on oral administration, exhibited significant decrease in gastric secretion in rabbits and showed anticholinergic effect in pylorus-ligated rats.
Flavones from rhizomes are strongly antifungal against a wide variety of pathogenic fungi, responsible for major skin diseases in eastern India. Flavones were also found to be active against a number of Gram-positive and Gram-negative bacteria.
The gingerols and diaryheptanoids constituents of the rhizome are potent inhibitors of PG synthetase (prostaglandin biosynthesizing enzyme); they can also be active against 5-lipoxyge- nase, an enzyme involved in leukotriene biosynthesis. (Natural Medicines Comprehensive Database, 2007.)
