Abstract
BACKGROUND: Plant remedies are often used next to conventional standard of care by cancer patients. However, user rates are often underestimated and physicians usually feel not equipped to counsel patients. Hence, routinely recording the use of phytotherapy and sufficient knowledge on herbal medicine of the medical staff are required to improve the situation. Appraising the current state of knowledge of medical students may offer insight if education on herbals needs improvement. Here, we propose a simple anamnesis tool to assess knowledge and usage pattern of medical plants and demonstrate how to extrapolate symptom cluster participants associated with plants investigated in this study focussing on the common symptom of oral discomfort. METHODS: By screening German literature (popular science, specialist's literature, books for the interested layman) on medical plants used for treating oral discomfort, we were able to deviate a list of plants most often recommended for treating oral discomfort and to develop an anamnesis tool to assess knowledge and usage of 16 different plants. A group of 120 head-neck cancer patients (under surveillance, after receiving treatment) and 168 medical students were questioned at a collaborating out-patient clinic and via an online survey, respectively, in 2020. Students were additionally asked to write down indications of the plants they used in daily life. Knowledge and usage pattern were compared between both groups. Primary component analysis and heat-map analysis were used to visualize common and distinguishing features. Network analysis and VENN diagrams were used to extrapolate data of the medical students' cohort. RESULTS: Head-neck cancer patients and students show similar knowledge. However, students used significantly more plants in daily life than patients (p < 0.001). Overall, the user rate of patients and students were 82.50 and 93.94%, respectively. The top five most commonly known plants were similar in both groups (Marticaria recutita L., Zingiber offinicale ROSCOE, Taraxacum Wigg. Calendula officinalis L.) with the exception of Salvia officinalis L. (patients' cohort) and Carum carvi/Cuminum cyminum L. (students' cohort). Despite this slight difference, usage pattern of the top five most commonly used plants was the same between the groups. Students' indications were compared to indications found in the literature, unmasking several differences between commonly practiced and written knowledge on German phytotherapy. Network analysis revealed, that students associated certain plants with corresponding symptom clusters (e.g., coughing, oral mucositis). CONCLUSION: The majority of surveyed cancer patients as well as medical students use phytotherapy for treating oral discomfort. Both groups know and use similar plants. However, indications of written folk medicine differ from the lived and practiced tradition.
