The first nursing school in the world was started in India in about 250 BC. Only men were considered "pure" enough to become nurses.

The Charaka (Vol I, Section xv) states these men should be, "of good behavior, distinguished for purity, possessed of cleverness and skill, imbued with kindness, skilled in every service a patient may require, competent to cook food, skilled in bathing and washing the patient, rubbing and massaging the limbs, lifting and assisting him to walk about, well skilled in making and cleansing of beds, readying the patient and skillful in waiting upon one that is ailing and never unwilling to do anything that may be ordered."
