text: Endocrinology is the branch of biology and medicine that focuses on the endocrine system, and although the terms "endocrine" and "endocrinology" didn't come into common usage until the 1800s, the study of endocrinology can be traced back to China over 2,000 years ago, according to American author Robert K.
