Phytin

 

the calcium magnesium salt of phytic acid; a widely distributed natural compound found in plants.

Large quantities of Phytin are found in bran and in oil cakes of cotton, hemp, and other plants. A therapeutic agent called Phytin is obtained from the substances. A white, amorphous, odorless powder poorly soluble in water, it is used in medicine to stimulate hematopoiesis, accelerate bone growth and development, and treat some neurological disorders.
