There is another previous use for the word soma, icant remember right now from which anciwnt culture it was but they divided the human entity into three essential parts; pneuma is the soul or spirit; sarx is the meat wo the soul, just the corpse; and soma is the body when pneuma is within it. So i think Soma is an addequate name for a medicine that treats body aches, this cannot be a coincidence, but pharmaceutics being not afraid of bad propaganda.
