I dont use certain spells in healing, but I have another good method for that.
sit and realax, ground yourself and take contact to the universe.
gather healing energies (pick one of them:)
-life energy - from mother earth, ground and color is green.
-universal energy - from universe, color purple (or white).
-holy light, from the heaven or universe or angels which ever you believe, color: shiny white.
and then send the energy where its needed throw your hands, because in our hands we have a chakra (yes it is a chakra, but not one of the main 7) which if for sending enegies to something.
if your healing yourself place your hands in the place where the illness is, if its everywhere then your head and slowly move your hands until there in your feet.
if its someone else do the same to that person, if you do it distant visulize the person or visulize yourself being there.
there is also one another method, which is abit dangerous for the healer if done wrong.
the idea is to push bad/sick energy from the target with your own energies (you can use one of those 3 healing energies for that too) and then fill the target with one of the healing energies. but remember that you should not have the sick energy to go mix with yourself, dont touch it at all, just push it away to a place where it disappears (example: universe or earth)
this will work for 100% if done right, but its more dangerous.
the first method will work about 50% sure, because the energy chouses what will be healed, and which is best for everything to happen.
yeah there are many chakras in us.
7 main chakras (root, navel, solar plexus, heart, throat, 3eye, crown), some believe that there are 11 main chakras (the 4 others are: hands, feet, second crown [silver] , third crown [golden] ) all of them do exist, but its just an opnion which are the main ones ;) + there are so many more, which most people haven't ever even heard from :D (I only know these 11 for sure)
