Stock up on everything you’ll need to make it through the winter with Tonic, a new book of recipes from wellness expert Tanita de Rujit. Whatever ails you, there’s a natural cure right around the corner. Make homemade digestive bitters, and quiet the roar in your gut. 

This is a tincture of bitter herbs, spices, roots and peels, infused in apple cider vinegar.

Bitter flavors get our digestive juices flowing. They help to soothe gas, burping, bloating and indigestion. They also balance our cravings for sweetness and keep our appetites in check, to prevent us from overindulging.

Sometime around 1824, Johann Siegert, a doctor in Venezuela, began making Angostura bitters as a stimulant for the troops, to help keep them on their feet. Even the ancient Egyptians were said to have infused medicinal herbs in jars of wine. Across Europe, bitters have been a core part of every meal, to prepare the digestive system for particularly heavy, fatty foods.
