There are several ways of solving it without going to a vet - that's the problem with this darn forum, all these hens are so dang judgmental. Some approaches you may recommend to your, "friend":
(1) Take off all of your clothes,with the exception of a zebra print thong, oil your body up with Crisco and dance around the snake while humming the chorus to "It's Raining Men".
(2) Drink a six pack of diet coke in less than 45 minutes. Urinate into a copper bucket. Run this through a humidifier in the room that the snake resides in. The dissolved metals in your urine mixed with the chemicals in the diet coke will react with the copper creating the seebeck effect. When nebulized, it will act as a potent lung tonic.
(3) It is possible that the snake does not have an RI, but is possessed by a malevolent spirit. In that case, you need to urge your friend to get that snake to a qualified herp exorcist immediately. If not, that poor animal's soul will be damned to eternal torment. Is you friend too cheap to save this animal from HELL?
You could have saved yourself a lot of drama and just found all these cures on Anapsid - the most informative reptile site on the intrawebs.
