If ever you are in need of healing, blessing or any kind of aid, I offer the votive candle lighting service. There is an invocation of the angel which rules the day pertaining to your specific request. Through the instructions of Sepher Razialis, a sacrifice will be left of incense and prayers given to the angel and his respective hierarchy. A votive candle is lit and blessings are asked for. The candle is left lit until it burns out (about 15 hours).
These are typically performed during a waxing moon on the day and hour of the Archangel needed but exceptions can always be made for emergencies.
