Anethole trithione is primarily used for its ability to stimulate salivary secretion, making it valuable in managing dry mouth (xerostomia), especially in patients undergoing radiation therapy for head and neck cancers or those with Sjögren's syndrome. It helps improve saliva production, which supports oral health, enhances comfort, and aids in chewing and speaking. The compound also exhibits hepatoprotective properties and has been used to support liver function in certain liver disorders. It may help in detoxification processes and is sometimes included in treatments aimed at improving bile flow and reducing cholestasis. Additionally, anethole trithione has been explored for its potential antioxidant effects, contributing to cellular protection against oxidative stress. Due to these combined actions, it is found in some pharmaceutical and supportive care formulations targeting salivary and hepatic health.
