I know you're being sarcastic, but mercury tonics have been a thing for the wealthy for a long time. IIRC emperor Qin Shi Huang was buried in a tomb with a literal river of flowing mercury and he spent the later years of his life consuming it to, ironically, try to live forever.
Lead is still incredibly toxic but I don't know of instances where people were actively consuming it.
