The history of mercury in medicine dates back thousands of years. There’s a good 4 page article in the Weston A Price Foundation about that. Check out westonapricefoundation.org. Search for history of mercury. There’s a 4 page article about mercury’s persistence in the May 4, 2018 edition.
Dentists began using it around the time of the Civil War believing mercury did not escape from the mixture of the amalgam, referred to as “silver fillings”. Current technology, like the Jerome meter, shows it is actually escaping. The short video clip, “The Smoking Tooth” is now online for all to see.
