Languas officinarum (Hance) P.H.Hô
Alpinia officinarum, known as lesser galangal, is a plant in the ginger family, cultivated in Southeast Asia. It originated in China, where its name ultimately derives. It can grow several feet high, with long leaves and reddish-white flowers. The rhizomes, known as galangal, are valued for their spicy flavor and aromatic scent. These are used throughout Asia in curries and perfumes, and were previously used widely in Europe. They are also used as an herbal remedy.
The genus is named for Prospero Alpini, a 17th-century Italian botanist who specialized in exotic plants. The word "galangal" comes from the Arabic form of a Chinese word for ginger, liang-tiang.
This herbaceous plant can grow up to ten feet in height, though three to five feet is more common. The leaves are lanceolate (long and thin), and the flowers are white with streaks of red, growing from a spike at the top. The plant's rhizomes, the part known as galangal, are thin and tough, and they are the principal reason the plant is cultivated. They have orange flesh with a brown coating, and have an aromatic odor and a pungent flavor. These are smaller than greater galangal.
The galangal rhizomes were widely used in ancient and medieval Europe, where they were reputed to smell of roses and taste of spice. Its use in Europe has dramatically declined, however, and is now mainly used in Eastern Europe. It is used in Russia for flavoring vinegar and the liqueur Nastoika. It is still used as a spice and medicine in Lithuania and Estonia.
Alpinia officinarum contains high concentrations of the flavonol galangin, which has been shown to slow the increase and growth of breast tumor cells. Historically, the rhizomes were reputed to have stimulant and digestive effects.
Lesser galangal is native to China, growing mainly on the southeastern coast, and it grows in Hainan, Japan, and Thailand. It is also cultivated in India. Hong Kong is the commercial center for the sale and distribution of the lesser galangal.
