In the literature, there have been at least 20 different chemotypes identified for thyme essential oil. The “typical” thyme essential oil presents a thymol content of 45% (range 31–50%), with significant concentrations of p-cymene (0.1–26.6%, average = 15.6%) and γ-terpinene (up to 22.8%, average = 9.3%). In addition, there are several other chemotypes of T. vulgaris rich in thymol and/or carvacrol [23]. Thymol has been identified as an anti-influenza agent against influenza type A and parainfluenza type 3 virus [24,25]. Lavandula angustifolia essential oil is rich in linalyl acetate (37.0–43.6%), linalool (19.7–39.1%), geraniol (up to 9.3%), β-caryophyllene (up to 5.1%), terpinen-4-ol (up to 14.9%), lavandulyl acetate (up to 5.5%), and borneol (up to 6.4%) [26,27,28,29].
