Lesser Galangal Rhizome (Gao Liang Jiang)
What is Lesser Galangal Rhizome (Gao Liang Jiang)?
Lesser Galangal Rhizome (gao liang jiang, 高良姜), also known as Rhizoma Alpiniae Officinarum, is the most important raw material in the famous Chinese medicinal ointments such as Tiger Balm, Universal Oil and Er Tian You. These ointments are one of the most convenient treatments for headaches, itchy skin, mosquito and insect bites.
A member of the Ginger family, Galanga is native to Southeast Asia. It has roots that are ivory or pale yellow with pink tips, as well as a hot and spicy taste. The roots of Galanga are usually harvested in the late summer and autumn. Used in Chinese Medicine and Ayurvedic Medicine for thousands of years, Gao Liang Jiang was brought to England and Northern Europe in the 13th Century by crusaders. Other than being used medicinally, Gao Liang Jiang was also used as a spice or seasoning in cooking, an ingredient in medicated wine and insect repellent. Galangal oil is also used to flavor French liqueurs, perfumes in India, digestive aid and even some tobaccos.
In Traditional Chinese Medicine (TCM), Gao Liang Jiang falls under the category of ‘Herbs that warm the Interior and expel Cold’. Hot in nature, Gao Liang Jiang can help individuals with too much Heat in their body, such as those experiencing a Yin Excess or a Yang Deficiency, to restore a harmonious yin-yang balance. Pungent in taste, Gao Liang Jiang can promote the circulations of qi and body fluids. In particular, the herb targets the Spleen and the stomach.
