History of Chinese Invention - Early Endocrinology

Early Chinewe proto-endocrinology

Endocrinology is a branch of medicine dealing with glands in the body that produce hormones. In the second century BCE, the Chinese were isolating sex and pituitary hormones from human urine and using them for medicinal purposes. They used methods such as sublimation of steroid hormones and the use of saponin (from the beans of Gleditschia sinensis) to extract hormones, but gypsum (containing calcium sulfate) was also known to have been used.

Endocrine glands and basic understanding of hormonal effects on bodily functions were understood by early Greek anatomists, but experimentation and therapy was not common until the advent of germ theory, physiology, and organ basis of pathology in the 19th century. English physicians in the early 20th century extracted "secretin" from the pancreas and coined the term hormone for chemicals influence the function of various organs.
