Theobromine is widely used in the food and beverage industry, particularly in chocolate production, as it contributes to the characteristic bitter taste of cocoa. It is also utilized in pharmaceuticals for its mild diuretic and vasodilatory properties, often found in medications for cardiovascular health. Additionally, theobromine is studied for its potential benefits in cough suppression, with some research suggesting it may be effective in soothing persistent coughs. In cosmetics, it is sometimes included in formulations for its skin-smoothing and antioxidant properties.
