The rootstock of galangal has shown an inhibitory effect in vitro on many pathogenic bacteria like anthrax bacillus, hemolytic streptococcus and various strains of Staphylococcus.Galangal is often recommended for motion sickness and morning sickness, an effect that is primarily attributed to ginger.Galangal can also be applied as a treatment for infections of the upper respiratory tract such as chronic bronchitis and cough. An extract of the root is used as a mouthwash and a gargle for mouth ulcers, gum inflammation and other inflammation in the mouth and throat and as a treatment for bad breath (halitosis).In the Middle East, there is a tradition of using the herb as a remedy for rheumatic pains and arthritis.In traditional Chinese medicine, galangal root is regarded as a warming herb that can be used for stomach pain, vomiting, hiccups, and diarrhea. When used against hiccups it is often combined with poor man’s ginseng (Codonopsis pilosula) and the fungi fu-ling (Chinese) also known as Indian bread (Wolfiporia extensa).
Historical Medicinal Uses and TraditionsThe herb has been used in both Chinese and Ayurvedic medicine since ancient times and still is. Galangal was first brought from the Asia to England and northern Europe in the 13th century by the crusaders and soon became a popular spice as well as medicine.The Medieval mystic Hildegard of Bingen recommended the herb as a tonic for the heart, and called it “the spice of life” and said it was a gift from God meant to keep diseases at bay.
