@Yazata mentioned the New Avatar Power, so I'll add the relevant incantation here:
I call thee ZOROEL and SABRIEL who have dominion over physical and mental health. At my command, banish from me all diseases, discomfort, sickness, and malfunction of body and mind.
Send down Your beneficial healing rays, for You ar able to bring this to pass. During each passing hour Your powers will bring youthfulness and freedom from pain.
I say this command with the healing words IMANUEL which Shadrach, Meshach, and Abed-nego sang in the fiery furnace and were delivered. Thus shall Your powers dispel this sickness and disease.
So mote it be.
(Zoroel and Sabriel are two angels originating from Jewish mysticism.)
Here's the book - it's disgustingly cheesy but has proved highly influential, never mind all its sensationalism and outrageous claims:

Just in case you're Catholic: Prayer is a lost art in that denomination, in my opinion. I speak from experience because I was an altar boy as a child and would often witness the old ladies congregating in church half an hour before mass to say the rosary. It was nothing more than a rote repetition of prescribed words; maybe some of them reached some altered state of consciousness like Hindus would when reciting a mantra over and over again but it wasn't praying in my book. And now I'm trying to pray, straight from the heart, but find it difficult to get out of that mindless prayer wheel mentality I was exposed to as a child.
It's been said that praying is for yourself, not for god because he is omniscient and knows exactly what you are going to say anyway. The biggest stumbling block for me has been really opening up without shame, guilt or embarrassment to supernatural, being authentically sincere without any inhibitions. God knows about your struggles and that you need help, so it's not about making an urgent request (which he may deign to grant provided you've been 'good' and confessed all kinds of real or imaginary sins) or desparate entreaties but about you opening up to divine healing.
There is a tradition of victim blaming in the Abrahmic religions, with claims of divine punishment for minor trespasses and rewards for walking the official doctrine line, or about beating your breast and declaring yourself unworthy of god's love. Forget all that, if you can. Invoke Christ or the Archangel Raphel and try to speak
with them, not
to them.
Again, no guarantees. Yes, and avoid that "God, Thy will be done" copout if you're serious about magic. True, you can't command god to do something for you but wheedling and humbly beseeching him is not the way to go, in my opinion. Make an emphatic request but don't grovel. Sincerly try to establish contact instead of talking into empty space like so many christians do.
