Galangal (Alpinia galanga), commonly known as greater galangal, is one of the most important medicinal and culinary plants in Southeast Asia. For centuries, galangal has played a significant role in the daily lives of local communities, not only as a spice and flavoring agent but also as a traditional remedy for various health conditions. Its distinctive aroma and pungent taste have made galangal an essential component of traditional medicine systems in many Asian countries, particularly Indonesia, Thailand, and Malaysia. Due to its numerous health-promoting properties, galangal is widely utilized in traditional medicine, pharmaceutical products, food and beverages, cosmetics, and dietary supplements.
Galangal belongs to the Zingiberaceae family, together with other well-known rhizomatous plants such as ginger, turmeric, and kencur. The plant is characterized by its large rhizome, reddish-brown outer skin, and aromatic white flesh. Compared with other members of the ginger family, galangal possesses a stronger and sharper flavor profile, making it highly desirable in culinary applications and herbal preparations. In addition to its culinary importance, galangal has long been used in traditional medicine to help relieve digestive disorders, reduce inflammation, alleviate muscle pain, and support respiratory health.

Owing to its diverse chemical composition and broad spectrum of biological activities, galangal continues to be cultivated and utilized as an important raw material for the development of herbal medicines, functional foods, skincare products, and health supplements.
