This Elderberry Tonic from our colleague and fellow herbalist, Kathy Langelier (Maine) combines elderberries and warming spices with raw apple cider vinegar to create a beneficial and delicious tonic. This herbal tonic blend is made with traditional ingredients that support healthy immune function throughout the year.**We hope you enjoy this power-packed immune boosting blend.Our herbal tonics are functional + fast absorbing and more bioavailable than apple cider vinegar pills or gummies. Herbal Revolution preserves the natural prebiotics and probiotics in their raw ACV by never heat-treating our tonics. These tonics are concentrated and never watered down. It's better for the planet not to ship water, and you get a more potent product! These tonics may be diluted in water if you prefer a milder flavor. Size: 8 oz Amber Glass Bottle (16 servings per bottle)
