There are also healer NPCs in existence; some factions provide them for their members. They charge you a one-time fee of a few hundred credits and instantly heal you back to full health. Useful for repeated brawls, if you don't have much HP.
They were only available for a limited time, though, so they may be rather rare these days.
At his health level it would heal him to full health, given the HP he cited in the first post. ^_^ You may be right that it is a limited quantity, though; I haven't used a medic myself aside from testing out of curiosity when they were first released. I did think it healed fully at that time, but I could be mistaken, or it may since have changed.
