Many of these oils, which can be found at various prices on the market and are claimed to be natural by manufacturers, are adulterated with other oils or synthetic substances. This study aims to provide samples of the essential oils, which are used in public, namely clove, neroli, tea tree, and cinnamon essential oils belonging to brands known to be sold widely on the market and to evaluate the compliance of these oils with the pharmacopoeia by conducting pharmacopoeia analysis. Among 25 essential oil samples evaluated with reference to the Turkish Pharmacopoeia (2017) within the scope of the study, only 2 of them were found to comply with the pharmacopoeia in terms of all tests. Investigating the compliance of essential oils with quality criteria is of great importance in preventing harm to the health of consumers and preventing them from purchasing unqualified products.
