Herbal antacid powder is a natural formulation developed to neutralize excess gastric acid and alleviate symptoms of acid reflux, heartburn, and indigestion. Unlike conventional antacids that may cause side effects with prolonged use, herbal antacid powders are composed of plant-based ingredients known for their gastroprotective, anti-inflammatory, and soothing properties. Common herbs such as licorice (Glycyrrhiza glabra), fennel (Foeniculum vulgare), amla (Emblica officinalis), and coriander (Coriandrum sativum) are often used in formulations for their efficacy in reducing acidity, improving digestion, and maintaining gut health. This abstract reviews the formulation, mechanism of action, and therapeutic benefits of herbal antacid powder, along with its safety profile. Emphasis is placed on the potential of herbal alternatives as effective and sustainable remedies in the management of acid-related gastrointestinal disorders
