They occur normally in the roots, wood , bark, leaves, and fruit of many plants, particularly in the bark of oak Quercus species and in sumac Rhus and myrobalan Terminalia chebula. They also occur in galls , pathological growths resulting from insect attacks. Commercial tannins typically are pale yellow to light brown amorphous substances in the form of powder, flakes, or a spongy mass. They are used chiefly in tanning leather , dyeing fabric, and making ink and in various medical applications.
