Sanguinarine is a natural alkaloid widely used in oral hygiene products such as toothpaste and mouthwash due to its antimicrobial and anti-inflammatory properties, which help reduce plaque, prevent gum diseases, and combat bacterial infections. It is also employed in veterinary medicine to treat certain infections in animals. In agriculture, sanguinarine serves as a natural pesticide to protect crops from pests and fungal infections. Additionally, it is researched for potential anticancer properties, showing promise in inhibiting the growth of certain cancer cells, as well as for skin conditions like psoriasis due to its antioxidant and anti-inflammatory effects. However, it should be used with caution, as high doses may cause side effects.
