Smoked about 2/5g imphepho [helichrysum petiolare]. There were definite hard to classify effects, fairly mild as for most ethnobotanicals; kind of calm, mild pleasant physical sensation - my back was ok so couldn't test analgesic qualities but no opioid feeling effects. There were occasional interesting perceptions of detail in the world and an altered framing of the visual field. As usual for me effects were stronger out of doors. Effects were immediate and decreased by about 1/3 in 1:15,then to about 1/2 original strength in 2 hours. Whether or not as a result of imphepho, dreams were more thoughtlike and less visual than usual, less memorable, less pleasant also.
Based on this single experience, imphepho is definitely active but mild, likely to be of interest to those interested in the broad spectrum of available ethnobotanicals but not to others. Hope this helps
