In brief: None
There aren't any that predictably slow the heart except foxglove which is the active ingredient in digitalis.
Digitalis has a very narrow therapeutic window with toxicity occurring easily. Taking foxglove to slow the heart would be like talking into metal cans strung together instead of using a phone.
