Magick cannot do the work alone but to my understanding, it is subtle and can help.
In the way prayers might help I'm thinking candle magick might also help. Blue candles are used for, healing and candle magick is easy to learn.
I've found some good books for it and even simple google searches can tell you simple candle color meanings. Candles are something that can be bought most places.
But as a disclaimer, it is of course no substitute a doctor or the medicine they prescribe.
