 "A. galanga is called laos in Indonesian and is the most common form of galangal used in cooking. It is also known as lengkuas and galanga root... Known as பேரரத்தை (perarathai) in Tamil, this form of ginger is used with licorice root, called in Tamil athi-mathuram (Glycyrrhiza glabra) as folk medicine for colds and sore throats." \\

 Dried sliced rhizomes of A.galanga contained 1.5% of acetoxychavicol acetate, which was active against seven  dermatophytes. MIC values ranged from 50 to 250 microg/ml. The compound was not found in rhizomes of A.officinarum, Zingiber officinale and Kaempferia galanga. \\

 "Four isomers of acetoxycineoles, (trans and cis)-2- and 3-acetoxy-1,8-cineoles, were identified as the odorous components of the rhizomes of greater galangal. Their structures were confirmed by comparing the retention indices by GC and the mass spectra with those of synthesized compounds. The concentration of trans-3-acetoxy-1,8-cineole was the highest among the isomers. The isomers presented individual odor features:  the (trans and cis)-2 isomers respectively exhibited woody and sweet aromas, while the (trans and cis)-3 isomers respectively showed sweet floral and camphoraceous aromas. Of these, trans-2-acetoxy-1,8-cineole seemed to have the strongest qualitative effect on the characteristic flavor of greater galangal." \\

+The acetone and ethanolic extracts of A.galanga were active in axenic (aerobic and anaerobic) and intracellular assays to determine the antimycobacterial potential. The aqueous extract did not demonstrate activity under the defined assay parameters. All three extract contained acetoxychavicol acetate. \\
+"A. galanga exhibits anti M.tb activity with multiple modes of action. Since the activity of the extracts was observed under reducing oxygen concentrations, it may be effective in treating the dormant and non-replicating bacteria of latent TB. Though the hypothesis needs further testing, A. galanga being a regular dietary component may be utilized in combination with the conventional TB therapy for enhanced efficacy." \\
