ABSTRACT
Production of hydroxy fatty acids in plants is of current interest principally due to the novel physical and chemical properties that are characteristic of hydroxy fatty acids. Castor oil is currently the only major source of hydroxy fatty acids. It has a long history in medicinal applications, serving as a laxative and during labor to promote the birthing process. Its compatibility as an emollient has promoted its use as a massage oil and in cosmetics. This chapter provides a brief description of hydroxy fatty acids, principally focused on castor oil, and discusses pharmacological and physiological applications.
