1851–1940
Known for challenging mainstream medicine in the early 20th century, this American physician wrote widely on diet, hygiene, and his theory of disease called "toxaemia." His books reflect a strong belief in self-care and natural health, ideas that helped shape later naturopathic thinking.

by J. H. (John Henry) Tilden
Born in Illinois in 1851, he studied medicine first under his father and later at the Eclectic Medical Institute in Cincinnati, graduating in 1872. He went on to practice medicine in the Midwest and eventually became closely associated with Denver, where he built much of his career.
He is best remembered for promoting natural hygiene and for arguing that many diseases stemmed from internal toxicity, an idea he called "toxaemia." He was sharply critical of drug-based treatment and wrote in a direct, practical style intended for both patients and general readers.
His published works include books on diet, child care, and disease, such as Toxemia Explained, Food: Its Composition, Preparation, Combination, and Effects, and Care of Children and Mothers. Although his medical theories sit outside modern mainstream medicine, his writing remains of historical interest for readers curious about early alternative health movements in America.
