Blood potion? What IS this thing for? Options

[Black Hand]

Ok, its driving me nuts. There is a small vial that can apparently be picked up in Oblivion Gates. It's Called "Blood Potion" It weighs nothing, and is worth nothing. Now I've yet to encounter another one, and, no, it is;nt in the random loot thingys.

Its RIGHT THERE in the middle of the outside walkways, lying on the ground.

I thought maybe it had something to do with the Vampire Quest. No Go.

It's probably just one of those things designed to make you post things like this, but if its not, please let me know.

There is indeed such a mod,as well some other pretty neat mods to make life easier for the vampire types...well...make LIFE easier isn't really correct is it?They aren't alive they are just...not dead?Or am i wrong?
Anyway there is a mod which ceates a vampire meeting place in the sewers under Imperial City where you can buy /sell anything you wish,feed on an uncontious cow t satisfy your thirst etc.
Try wikipedia if vampire charachters are interested.
Because i read that mod's info i think that blood vials are for that use.
