I love Raphael, he does great work. If I may, here is some advice in working with him.
I evoke him facing South and charge the ritual with the element of Fire before the evocation. I noticed the results are faster, and he seems to speed up the whole process. I just did this two nights ago for my wife. She works in a high stress environment and during cold season she is really sick and miserable for a month at least.
Raphael started working on her and speed up the time her cold would run. She got worse for a few hours (she told me that she felt like she was burning up, but she was not running a fever) she fell asleep and the next morning she was almost 100%. Now she is running in the mountains with our dogs completely healthy.
Good luck with Raphael, he is a great physician and kind of a smart ass (in my experience).
