Herbal medicines are widely used by cancer patients, often without clinical guidance. This case-based review explores five real-world cases where herbal supplements (Curcumin, Ashwagandha, St. John’s Wort, Green Tea extract, and Giloy) significantly interacted with anticancer therapies, leading to reduced efficacy or toxicity. Each case is expanded with clear mechanistic explanations and accompanied by a summary table. The aim is to raise awareness among pharmacy students and clinicians about the clinical consequences of unsupervised herb use in oncology.
