Products commonly known as herbal products often have drug contents which can result in harmful herb-drug interactions (HDI).
A number of herbal products may affect the properties of prescription drugs, leading to alterations in the drugs' effectiveness as well as potentially dangerous side effects.
The British Journal of Clinical Pharmacology analysis included 49 case reports and two observational studies with 15 cases of adverse drug reactions. The majority of patients were diagnosed with cardiovascular diseases, cancer, and kidney transplants and were receiving mostly warfarin, alkylating agents, and cyclosporine, respectively.
The research is warranted to increase patient awareness of the potential interaction between herbs and prescribed medicines and their consequences to curb herb-drug interactions (HDI) as a potential health problem.
