    Jean Baptiste van Helmont was the founder of the iatrochemical school which looked to chemical explanations of vital phenomena. He was a man of great intellectual curiosity and studied philosophy at Louvain. Disappointed with the content of the course he turned to law and after further disappointment decided to study medicine.

    Van Helmont’s teaching revolved around two terms, Blas and Gas. He was much influenced by the doctrines of Paracelsus and, like Paracelsus, believed that each material process of the body was presided over by a special spirit. This he called Blas. Physiological processes were themselves chemical, being activated by a special ferment (or Gas) and were also presided over by a special spirit. This spirit, in turn, was governed by a sensory motor or sensitive soul located in the folds of the stomach, especially its orifice. It was thought that the duumvirate of stomach and spleen regulated the functions of life and that when the duumvirate “withdraws its government” epilepsies or other diseases resulted. Van Helmont conceded that the “occasional nest” of epilepsy could be in the head or feet. Although the disease originated in the stomach he considered it could be provoked by strong emotions affecting the sensitive soul.

    There was another disease which van Helmont thought related to epilepsy. This was asthma. It had its original seat in the duumvirate. It affected and shook the whole body, but then concentrated on the lungs—whereas epilepsy made itself felt in the head. Van Helmont was so impressed by the apparent analogy between the two diseases that he stated “we may lawfully, therefore, by a Phylosophical Liberty name an asthma the falling sickness of the lungs”.

    Van Helmont believed in Paracelsus’ weapon salve, which healed by anointing the weapon instead of the wound. He became involved in a controversy regarding the   weapon salve and magnetic and sympathetic healing. In 1624 the Inquisition denounced his views and declared him suspect of heresy. His chief work Ortus Medicinae was published in 1648 after his death.

    Van Helmont was honoured philatelically on a Belgium stamp issued in 1942 (Stanley Gibbons 989, Scott B322).
