Changes in taste and smell can occur during chemotherapy treatment. These chemotherapy-related side effects can negatively impact patients' quality of life and diet.
The aim of this research is therefore to propose a solution to alleviate these taste and smell disorders. Based on the same principle as rehabilitation proposed for anosmia (loss of smell) related to COVID-19, we hypothesize that olfactory rehabilitation (using the sense of smell) through the odorous properties of essential oils could be effective for chemotherapy-related taste and smell alterations.
