Used by the Aztecs and Native Americans, Mexican Tarragon is usually reported to be a sedative, but with others claiming the opposite (stimulation). I found the effects to be mild, at best, perhaps edging to the former if anything. However, as with a number of botanicals in this class I did subsequently experience a degree of vivid and lucid dreaming, with later research revealing that this is indeed viewed as an oneirogenic in some quarters.
