There are 2 main ways to heal other than standing around waiting. You can use a fap or emt kit, or find a healing chip for mindforce. The TT sells a fap-5 (first aid pack) and there are many others found throughout the game, plus the emt kits that can be crafted.
Franck's fap guide gives a good look at what you can expect from a fap:

The mindforce heal chip stats can be found in the guide linked with the implants.
