Physiology

The will go completely dormant in late fall, even in the tropics where it is native. During dormancy care should be taken not to keep the soil too wet, but during the growing season it should be grown in well drained woodland soil kept regularly watered, and mild applications of fertilizer might be needed if the soil is low in nitrogen
The reproduction is through rhizomes and sexually through the production of flower

Habitat

In open grasslands at low and medium altitudes. It is best planted in a humid and covered area. It is a native of south India. It is found primarily in open areas in southern China, Taiwan, Combodia and India. It is also widely cultivated throughout Southeast Asia. As an ornamental, it makes an interesting groundcover.

Rhizome contains a volatile oil and small amounts of cinnamic acid ethyl ester, borneol, camphene, cineol, paraumarin, cinnamic acid, and anisic acid.• Also contains a small amount of alkaloid. Also, a lot of starch, gum, and mineral matter. Rhizomes are carminative, stimulant, expectorant and diuretic. The rhizome contains about 2.5 to 4% essential oil, whose main components are ethyl cinnamate (25%), ethyl-p-methoxycinnamate (30%) and p-methoxycinnamic acid; furthermore, 3-carene-5-one was found (Phytochemistry, 26, 3350, 1987). Other literature reports 4-butylmenthol, β-phellandrene, α-terpineol, dihydro-β-sesquiphellandrene, pentadecane and 1,8-cineol. The rhizome is also reported to display cytotoxic properties. (Chem. Pharm. Bull., 33, 3565, 1985).

Scientific Studies of K. galanga

•Extracts of the plant using methanol have shown larvicidal activity against the second stage larva of dog roundworm (Toxocara canis).

• It was also found to be effective as an amebicide in vitro against three species of Acanthamoeba which cause granulomatous amebic encephalitis and amebic keratitis.

•In 1999 the rhizome extract was found to inhibit activity of Epstein-Barr virus.

•Further research has demonstrated that the extract effectively kills larvae of the mosquito Culex quinquefasciatus and repels adult Aedes aegypti mosquitoes, both of which are serious disease vectors.

•wound healing activity of alcoholic extract of Kaempferia galanga in wistar rats: Phytochemical screening revealed the presence of flavonoids in K galanga with enhanced wound contraction effect that could be of use in the healing of open wounds.

•Sedative activity of hexane extract of Keampferia galanga L. and its active compounds: Study results showed considerable sedative and relaxant effects suggesting a potential for its application in aromatherapy.
