About Black Ginger （ Kaempferia parviflora ）
Kaempferia parviflora is a plant commonly known as Black Ginger or Krachai Dam (meaning “Black Ginger” in Thai) belongs to the family of Zingiberaecae. In Thailand, it has been traditionally consumed by infusing the rhizome part for joint pain in the knees and back. Since Black Ginger is a very difficult plant to cultivate, we visit the fields several times a year to check the growth of the plants to ensure supply stability and quality consistency.
