* Pre-clinical in vitro study. ** Pre-clinical in vivo study. *** Clinical study. N.B.: This table is non-exhaustive, broadly elucidating selected compounds and some of their potential pharmacological effects currently present in the pre-clinical literature. Depending on study parameters, the compounds show differing, sometimes biphasic, affinities and effects at different targets, thus highlighting the contradictory and equivocal evidence state. For a more extensive review on terpene mechanisms of actions and pharmacological effects, see these extensive reviews on the subject: Goncalves et al. [225], Liktor-Busa et al. [226], and Odieka et al. [33,71].
