Names

A. galanga rhizomes

The name "galangal" is probably derived from Persian qulanjan or Arabic khalanjan, which in turn may be an adaptation of Chinese gao liang jiang. Its names in North India are derived from the same root, including kulanja in Sanskrit, kulanjan in Hindi, and kholinjan in Urdu.[2]

The name "lengkuas", on the other hand, is derived from Malay lengkuas, which is derived from Proto-Western Malayo-Polynesian *laŋkuas, with cognates including Ilokano langkuás; Tagalog, Bikol, Kapampangan, Visayan, and Manobo langkáuas or langkáwas; Aklanon eangkawás; Kadazan Dusun hongkuas; Ida'an lengkuas; Ngaju Dayak langkuas; and Iban engkuas. Some of the names have become generalized and are also applied to other species of Alpinia as well as for Curcuma zedoaria.[3]

Alpinia galanga is also called laos in Javanese and laja in Sundanese. Other names include romdeng (រំដេង) in Cambodia; pa de kaw (ပတဲကော) in Myanmar; kha in Thailand; nankyo in Japan; and hong dou kou in Mandarin Chinese.[4] In Tamil it is known as a "பேரரத்தை or பெரியரத்தை" ("Pae-reeya-ra-thai"), widely used in Siddha Medicine and in culinaries. In Sri Lanka it is known as Araththa (අරත්ත).[5]

History of domestication

Lengkuas is native to Southeast Asia. Its original center of cultivation during the spice trade was Java, and today it is still cultivated extensively in Island Southeast Asia, most notably in the Greater Sunda Islands and the Philippines. Its cultivation has also spread into Mainland Southeast Asia, most notably Thailand.[6][7] Lengkuas is also the source of the leaves used to make nanel among the Kavalan people of Taiwan, a rolled leaf instrument used as a traditional children's toy common among Austronesian cultures.[8]

Description

The plant grows from rhizomes in clumps of stiff stalks up to 2 metres (6 ft 7 in) in height with abundant long leaves that bear red fruit. This plant's rhizome is the "galangal" used most often in cookery. It is valued for its use in food and traditional medicine. The rhizome has a pungent smell and strong taste reminiscent of citrus, black pepper and pine needles. Red and white cultivars are often used differently, with red cultivars being primarily medicinal, and white cultivars primarily as a spice.[6][7] The red fruit is used in traditional Chinese medicine and has a flavor similar to cardamom.

Culinary uses

Tom kha kai, a Thai dish

The rhizome is a common ingredient in Thai curries and soups such as tom kha kai, where it is used fresh in chunks or cut into thin slices, mashed and mixed into curry paste. Indonesian rendang is usually spiced with galangal.

It is also traditionally fermented with honey to produce the wine known as byais among the Mansaka people of the Philippines.[9]

Traditional medicine

Alpinia galanga (L.) Willd.

Under the names 'chewing John', 'little John to chew', and 'court case root', it is used in African American folk medicine and hoodoo folk magic. In Unani medicine 'A.Galanga' is called as 'Khulanjan' and its actions and uses have been mentioned in many unani classical literatures like Al qanun fittib The Canon of Medicine, maghzanul mufradath etc. It is considered as Muqawwi qalb (cardiac tonic), mufarreh, munaffise balgam, muqawwi meda, muqawwi bah etc. Its used in Asthma, cough, sore throat and other illnesses. Famous unani drug preparations with Khulanjan as an ingredient include Habb e Jadwar, Jawarish Jalinus, Jawarish Ood shirin etc.

Ayurveda considers A. galanga (Sanskrit:-rasna) as a Vata Shamana drug. 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.

Potential pharmacology

The rhizome has been shown to have weak antimalarial activity in mice.[10]

An ethanol extract of the rhizome has been shown to increase sperm count in rats.[11]

The ginger plant's androgenic properties may be useful in treating male sexual dysfunction; a triple-blind clinical trial found Alpinia galanga extract effective in alleviating erectile dysfunction induced as a common side effect of selective serotonin reuptake inhibitor (SSRI) antidepressant medications.[12]

Chemical constituents

Alpinia galanga rhizome contains the flavonol galangin.[13]

The rhizome contains an oil known as galangol, which upon fractional distillation produces cineol (which has medicinal properties), pinene, and eugenol, among others.[14]
