Pharmacists and physicians have a vital role to play in the monitoring of patients on alternative/herbal medication. Contrary to popular belief, natural medications do not necessarily mean safe medications. Many alternative/herbal medications have adverse effects that are not well known or well documented. As such, health care professionals should cautiously guide patient use of alternative/herbal medications. This case report describes an adverse reaction associated with the use of quercetin containing bromelain in a patient with non-small cell carcinoma of the lung.
