Cultivated for its medicinal and edible properties, it is also grown as an ornamental plant. Pink and blue ginger (Curcuma aeruginosa Roxb.) has the same medicinal properties as black turmeric (Curcuma caesia) though they are different species in the genus Curcuma. Both are mainly used medicinally, most commonly to prevent cancer cells from growing. This herb treats bronchitis, pneumonia, asthma, and pain relief caused by toothaches, osteoarthritis, and stomach disorders. Turmeric (Curcuma longa) is in the same genus, but it is a different plant from these two. Discover Pink and Blue Ginger (Fen Hong He Lan Jiang) and other herbs by visiting our Herb Directory.
