Formulation and Evaluation of Herbal Antiemetic Aromatherapy Roll-On

Abstract

This study focuses on the formulation and evaluation of a herbal antiemetic roll-on using essential oils derived from medicinal plants such as peppermint, ginger, lemon, and tulsi. Emesis (vomiting) is a complex physiological response triggered by various stimuli, including gastrointestinal irritation, motion sickness, pregnancy, and chemotherapy. Conventional antiemetic drugs, although effective, are often associated with adverse effects, creating a need for safer, natural alternatives. Aromatherapy, a holistic therapeutic approach utilizing essential oils, offers potential benefits in managing nausea and vomiting through olfactory and transdermal mechanisms. The formulated roll-on was prepared using selected essential oils blended with a carrier oil and evaluated for physicochemical properties and in-vitro antiemetic activity using a 5-HT₃ receptor binding assay. The results demonstrated a dosedependent inhibition of receptor binding, with a significant IC₅₀ value of 3.56 µg/mL, indicating promising antiemetic potential. The formulation exhibited comparable activity to standard drugs like ondansetron, suggesting its effectiveness as a natural alternative. Overall, the study highlights the therapeutic potential of herbal aromatherapy-based formulations in managing nausea and vomiting, with advantages such as improved patient compliance, reduced side effects, and ease of application. Further in-vivo and clinical studies are recommended to validate these findings.
