context_page_description: Christian Friedrich Samuel Hahnemann was a German physician, best known for creating the pseudoscientific system of alternative medicine called homeopathy.
context_section_description: Around the start of the nineteenth century Hahnemann developed a theory, propounded in his 1803 essay On the Effects of Coffee from Original Observations, that many diseases are caused by coffee.  Hahnemann later abandoned the coffee theory in favour of the theory that disease is caused by Psora, but it has been noted that the list of conditions Hahnemann attributed to coffee was similar to his list of conditions caused by Psora.
