Days Gone By: The art of medical diagnosis, circa 1851:

When Sylvester Graham died in 1851 the cause of death was listed as 'Congress waters and tepid baths.'

According to the records in Northampton City Hall, the eccentric health food pioneer remembered for inventing the graham cracker died at the age of 57 from drinking too much mineral water and ignoring his own advice to bathe in bracing cold water.

And treatments weren't much better.
