Minions gain more and more degen as they live. So by healing them, you're prolonging their lives, and adding to their natural degen. So it's not just you =)
minions gain degen over time, using blood of the master heals them and that is it. after i think it is 20 seconds they gain another point of degen. they keep gaining degen till they die. So don't worry about your blood of the master, it isn't doing anything but healing them and hurting you.
Blood of the master / healing your mins is ony good to keep them alive till you can get new corpses, in which case there wouldnt be any enemys around to take advantage of your attempted suicide.
