Addphealth
addphealth <number>
Adds <number> to the player's strength. <number> may be positive or negative.
The game enforces limits on the health added with this command. This size of the limit is set by MAXPLAYERHEALTH for most actors. A MAXPLAYERATOMICHEALTH is defined in con but does not appear to be passed in through gamestartup. The atomic health definately does have a higer limit but to find out where this is set from would require checking the source.
