Abstract
Kaempferia galanga L. (KG), commonly known as cekor is one of those precious medicinal herbs of Zingiberaceas that are still included in un-utilized herbs inspite of the variety of useful pharmacological properties it possesses. Extracts of KG have anti-inflammatory, analgesic, nematicidal, mosquito repellent, larvicidal, vasorelaxant, sedative, antineoplastic, antimicrobial, anti-oxidant, antiallergic and wound healing properties. Here, we have reviewed all the reported pharmacological properties of this valuable herb with an intention to highlight the effectiveness and potentials of this herb. Ethyl-p-methoxycinnamate and ethyl-cinnamate are found to be the most vital constituents responsible for most of these pharmacological properties. Antinociceptive effect of KG extracts is comparable with that of aspirin whereas its nematicidal effect is even more potent than Carbofuran and metham sodium. Key words: Antinociceptive, nematicidal, cekor.

There is a remarkable difference between the higher ethyl-p-methoxycinnamate content ( 25.96 to 87.4%) of KG and contents of the same constituents in K. marginata (4.46%) which strongly discourages the misuse of K. marginata as KG in many areas of the World (Yu et al, 2000)
