Ginger is a perennial plant that grows in India, China, Mexico, and several other countries. The rhizome (underground stem) is used as both a spice and in herbal medicine.

Curcumin is the principal curcuminoid of the popular Indian spice turmeric, which is a member of the ginger family (Zingiberaceae). The other two curcuminoids are desmethoxycurcumin and bis-desmethoxycurcumin. The curcuminoids are polyphenols and are responsible for the yellow color of turmeric. Curcumin can exist in at least two tautomeric forms, keto and enol. The enol form is more energetically stable in the solid phase and in solution.

Curcumin can be used for boron quantification in the so-called curcumin method. It reacts with boric acid forming a red colored compound, known as rosocyanine.

Curcumin is brightly colored and may be used as a food coloring. As a food additive, its E number is E100.
