Fire cider is a spicy, immune-boosting folk tonic made with apple cider vinegar, garlic, ginger, horseradish, citrus, herbs, and hot peppers. Used for generations to support digestion, fight colds, and boost circulation, it's taken in small doses or added to recipes. Steeped for 3–6 weeks, then strained and sweetened with honey, it’s a powerful natural remedy that can be added to drinks, dressings, marinades, and more.
