Warm, spicy, and energizing, ginger oil comes from ginger root (Zingiber officinale), a pungent, peculiar-looking underground rhizome. A member of the Zingiberaceae plant family, this perennial herb grows up to three to four feet high, with narrow spear-shaped leaves, white or yellow flowers, and small tuberous rhizomes with a thick or thin brown skin. Its flesh can be yellow, white, or red, depending on the variety.
