Career[edit | edit source]

In the late 19th century, Tyrrell established the J.B.L. Cascade Company in New York City. The company's flagship product, the "J.B.L. Cascade," was a home-use device for colonic irrigation. Tyrrell marketed the device as a cure-all for various ailments, including constipation, headaches, and skin conditions. His marketing strategies were innovative for the time and included direct mail advertising and the publication of a monthly health magazine.

Despite the popularity of the J.B.L. Cascade, Tyrrell's claims about its health benefits were controversial. Many in the medical community criticized his promotion of colonic irrigation as a cure-all, arguing that it was at best ineffective and at worst potentially harmful. Nonetheless, Tyrrell's device and the broader practice of colonic irrigation have remained popular among certain segments of the public into the 21st century.

Later Life and Legacy[edit | edit source]

Tyrrell continued to run the J.B.L. Cascade Company until his death in 1918. His legacy is a complex one. On one hand, he is remembered as a pioneering entrepreneur in the field of home health care products. On the other hand, his promotion of colonic irrigation as a cure-all has been criticized as an example of quackery in the history of medicine.
