The production method has a strong influence on the quantity and quality of essential oils (EO) extracted from aromatic plants, and is often omitted in the reports of studies carried out in this field. The objective of this document is to highlight the importance of constantly and systematically describing the production conditions of oil plants, in order to make the experiment easily replicable. The approaches of different authors are described in the document in relation to their efforts to elucidate the effect of environmental stimuli in the synthesis and composition of the oil, taking as an example the case of oregano to emphasize the resulting variation as a consequence of different stimuli within the same species. Additionally, we present the results of a pilot trial of 2 months of "curing" of leaves of Lippia palmeri W. which showed an increase in the total proportion of the thymol compound from 17.54 to 66.80%. It is assumed that in many cases, the lack of widespread production of natural products is largely due to the great variability in the composition of the final product, so a checklist is proposed as a first guide to carry out the research on the obtaining of EO, specifically on the production method.
