Used as an antiviral agent, particularly in the treatment of viral infections such as influenza and hepatitis. It works by stimulating the production of interferons, which are proteins that help the body's immune system fight off viruses. Also investigated for its potential in treating certain autoimmune diseases due to its immunomodulatory effects. Has been studied for broad-spectrum antiviral activity, including against some RNA viruses. Not widely approved in Western countries but used in some regions for prophylaxis and treatment during viral outbreaks.
