Herbal supplements are normally categorized as dietary supplements. Many supplements contain active ingredients, and those ingredients might cause side effects or unexpected risks.
Even though scientific studies do not often support herbal remedies, more and more people use herbal supplements. Some herbal supplements have drug-like effects, but sometimes they could be harmful as well. If you decide to take herbal supplements, you need to know their potential side effects. You will also need to consult your doctor, especially if you are taking medications, or have chronic health issues, or are pregnant or breast-feeding.
