**Brief introduction:**
Galangal is a perennial rhizomatous herb native to Southeast Asia and southern China. Closely related to ginger, it possesses a warm, aromatic, peppery flavor with hints of citrus and pine. For centuries it has been used both as a culinary spice and medicinal herb in Traditional Chinese Medicine, Ayurveda, Unani medicine, and Southeast Asian folk traditions. Medieval European physicians also prized Galangal as a digestive, stimulant, and warming remedy.

* Introduced into Europe through medieval spice trade routes
* Recommended by Hildegard of Bingen for heart and digestive complaints
* Used as both a medicinal herb and culinary spice throughout Asia
**Parts used and method of use:**

**Use in healing (modern herbal practice):**
* Digestive stimulant and carminative
* Relief of nausea and motion sickness
* Support for mild respiratory congestion
* Anti-inflammatory support
