I've been experimenting with making various digestifs or tinctures of herbs that help with digestion. Pictured are tinctures of (left to right) basil, mint, licorice (glycyrrhiza glabra), sichuan pepper, and fennel, soaked for a week or so in cheap vodka (80 proof).
The sichuan pepper is experimental and pretty intense: it numbs your mouth and makes you want to throw up...the rest are carminatives known to help digestion. Basil, mint, and fennel are my favorites. You can mix equally with simple sugar syrup to make them tastier.
