The perils of St. John's wort in cancer care: Nursing considerations.

Abstract: Approximately one-third of Americans use healthcare approaches including herbs and botanicals, such as St. John's wort (SJW), to improve overall well-being, gain control over their health, and manage the adverse reactions of conventional therapies. This article examines the use of SJW in cancer care, discussing its pharmacokinetics, toxicity, and potential interactions with cancer treatments while emphasizing the importance of patient education and collaboration between oncology nurses and pharmacists to ensure safe and effective care.
