A tonic is usually something to perk you up but it's hard to see how this Hematic Tonic would do that. It contains strychnine, arsenic and mercury. That's one deadly poison and two toxic metals. The dose is 1 to 2 pills after each meal. It was sold by Upjohn from 1920 to 1929. Back then the FDA was brand new and it took decades for it to stop the sale of all medications like this that did more harm than good.
