Herbal supplements are dietary products that contain natural herbs or plants, which are used to promote overall health and well-being. These supplements can help support various bodily functions such as digestion, immune system function, energy levels, and mood regulation. They are often marketed as a way to improve specific aspects of one's life, whether it be for stress relief or better sleep. Herbal supplements are generally considered safe when taken in appropriate doses and under the guidance of a healthcare professional if needed.
