(Lamiaceae family), a species also treated as in a recently segregated genus from , is a perennial herb or subshrub native to the Andes of northern South America. leaves are commonly used in traditional medicine to treat respiratory and digestive illnesses. In this study, plants at different phenological stages (vegetative, flowering, and post-flowering) were harvested to obtain essential oils (EOs) and extracts (from fresh plant materials or post-distillation waste) whose chemical compositions and antioxidant activities were determined.

- The study introduces circular economy principles in essential oil production to minimize waste and enhance the use of plant materials, potentially offering a viable economic alternative to coca cultivation in Colombia.
- It utilizes Java-type citronella and palmarosa plants, employing distillation techniques to extract essential oils and subsequently extracting bioactive compounds from the residual biomass.
- The results show typical essential oil yields, confirm compliance with ISO standards for chemical composition, and reveal that the hydroalcoholic extracts possess significant antioxidant activity.
