Efficacy of External Application of Rosemary Oil in Patients With Chemotherapy-Induced Peripheral Neuropathy: a Feasibility Study

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common severe dose-limiting side effects that accompany treatment with different chemotherapeutic agents. Patients with CIPN often experience a reduction in quality of life and an increase in fall risk due to symptoms such as pain, sensory loss, paresthesia (tingling, numbness), and gait disturbances. Treatment of CIPN is based on pharmacotherapy, which may in turn cause side effects such as nausea, dizziness, fatigue and others. In addition, various approaches from integrative medicine are used, e.g. acupuncture, touch therapies, mind-body medicine, dietary supplements, and aromatherapy. Little is known about the effect of rosemary oil, applied to hands and feet, on CIPN. The present study is a feasibility study to determine the feasibility of a future clinical trial to investigate the efficacy of topical application of rosemary oil in cancer patients undergoing chemotherapy who develop CIPN.
