What are the dangers of drug interactions with herbal medicines?

Plants have been used in the treatment of many diseases since ancient times, while also having served as a major source of modern single compound drugs. Herbal medicines continue to be widely used globally due to specific health beliefs [1,2] and due to scientific information becoming more and more available on their benefits to patients as well as their safety [3]. It is true that many plants that have been used traditionally for therapeutic and culinary applications are generally safe, but it is also important to know that some plants are highly toxic and can even be deadly [3]
