The Schola Medica Salernitana was an early medieval medical school in the south Italian city of Salerno and the most important native source of medical knowledge in Europe at the time. The school achieved its splendour between the 10th and 13th centuries, during the final decades of Longobard kingdom. In the school, women were involved as both teachers and students for medical learning. Among these women, there was Trotula de Ruggiero (11th century), a teacher whose main interest was to alleviate suffering of women. She was the author of many medical works, the most notable being De Passionibus Mulierum Curandarum (about women's diseases), also known as Trotula Major. Another important work she wrote was De Ornatu Mulierum (about women's cosmetics), also known as Trotula Minor, in which she teaches women to conserve and improve their beauty and treat skin diseases through a series of precepts, advices and natural remedies. She gives lessons about make-up, suggests the way to be unwrinkled, remove puffiness from face and eyes, remove unwanted hair from the body, lighten the skin, hide blemishes and freckles, wash teeth and take away bad breath, dying hair, wax, treat lips and gums chaps.
