depends on what your idea of medicinal is. generally, people think of that as meaning indica dominant stoney gear, but sativa doms have their medicinal uses too.
high quality seeds' haze x skunk had UNDENIABLE medicinal effects for me. first, it got me to break my drinking a 6 pack of 16 ouncers every night and nearly choking to death on puke almost with every morning's burp to reflux. fucking A, i'd call that virtually life saving med use! not only that, but it helped me lose most of my beer gut in only a month or so by being able to just ignore hunger pangs by staying focused on whatever i was already doing and not wanting to be interrupted. it might be good for pain relief by letting you tune it out. i would get REALLY hungry blazing it, but it was all good. it's euphoria level was good for depression & the motivation was great for exercise too.
i didn't have a lot of it to test, but mandala's 8 miles high is good meds to me too. it just made me smile & smile & smile and it loves music & dancing. that's more antidepressant & motivational med use to me.
for me. indicas are "bad medicine" because they just make me tired & depressed. my biochemistry just doesn't like them at all.
if you REALLY want some serious anti-depressant motivation gear, try kali mist by serious seeds. that one won't let you sit still! no shit! i tried kicking back to tunes on it when i was gifted a gram of original crushed red pepper tasting and couldn't stay focused and ended up cleaning my house with an ear to ear grin. i could see that effect being a direct threat to addictive diet pill pharmaceuticals. one of the reasons that weed is illegal really. kali mist is also supposed to be a favorite with the ladies for menstrual cramps, but i think it really just makes them to happy to give in to their inner bitch on rag week. LOL joey weed's discontinued (all of his gear is apparently) C99, at least, had a very similar buzz in a much faster flowering package. mosca's is a different pheno that's supposed to be trippy where kali mist & JW cinderella are very clear headed.
the BEST two strains for depression might just be jilly bean & laughing buddha though with the former being stony & the latter more sativa leaning. i SERIOUSLY doubt either of those would drive anyone into committing suicide as anti-depressants ironically can do.
that's my take on med use. for me, getting high really is the nest medicine in the world. they help with my innate procrastination
