Ayurveda uses minerals and plant-based salts along with herbal formulations to correct deep-rooted imbalances in the body. Lavan (medicated salts) and Kshar (alkaline preparations) are two such powerful Ayurvedic dosage forms, primarily known for their action on digestion, metabolism, urinary system, and detoxification. Due to their sharp and penetrating properties, they are used carefully under expert guidance.
