Use and safety of dietary and herbal supplements among hospitalized patients: What have we learned and what can be learned?-A narrative review

Gaps in knowledge regarding DHS include their use by hospitalized patients in developing countries; specific association between comorbidities and DHS use; assessment of actual side effects from DHS; barriers to physician inquiry on DHS use; and DHS documentation. DHS use by inpatients is extensive and involves safety as well as medicolegal considerations. Although much has been learned on this topic, further research is needed on the conduct of both patients and physicians regarding DHS.
