Sand Ginger (Kaempferia galanga), commonly known as kencur, aromatic ginger, cutcherry or resurrection lily, is known in Thai as praw haawm (เปราะหอม) or waan haawm (ว่านหอม)
Sand ginger has a peppery camphory taste. It is one of four plants known as galangal, and is differentiated from the others by the absence of stem and dark brown rounded rhizomes, while the other varieties all have stems and pale rose-brown rhizomes.
It is belongs to the ginger family and can be found primarily in open areas in southern China, Taiwan, Cambodia and India, but is also widely cultivated throughout Southeast Asia.
It is not commonly used in Thai cuisine except for few dishes and can be bought as a dried rhizome or in powder form at spice shops or herbal medicine stalls.
It is also used in Chinese cooking and Chinese medicine and is sold in Chinese groceries under the name Sha Jiang (Chinese: 沙姜).
Its essential oils have been used in Chinese medicine for treating indigestion, cold, pectoral and abdominal pains, headache and toothache. Its alcoholic maceration has also been applied as liniment for rheumatism.
