As the world embarks on unprecedented research efforts to prevent and treat the COVID-19 coronavirus, patients with cancer and healthcare providers alike may be interested in using herbal products to boost their immune system or relieve anxiety and stress. However, finding accurate information is challenging: no herbs have been scientifically proven to prevent or treat COVID-19, and some may even cause harm.

The following evidence-based information on popular herbs used for immunity and to relieve anxiety and stress is adapted from the Memorial Sloan-Kettering Cancer Center’s About Herbs (https://www.mskcc.org/cancer-care/diagnosis-treatment/symptom-management/integrative-medicine/herbs) website. The links will take you to the full monographs to learn more about adverse effects and herb-drug interactions.

Oncology nurses have an important role in informing patients that no herbs can cure COVID-19, that indiscriminate use of herbal supplements is unsafe, and that supplements have the potential to interact with prescription medications. The best way to prevent or treat COVID-19 is to follow advice from healthcare authorities and clinicians, not self-medicating with herbs and supplements.
