Arsenic is a medicine in small enough doses.

So is mercury. It's used as a preservative in injections for babies and

Prior to antiboitics, it was used to treat VD.

Each person, on average, releases 3g of mercury into the
atmosphere when they are cremated, from tooth fillings.
That adds up to more than all other sources of environmental
contamination with mercury added together.
