UPDATE:

The aya treatment especially in this case should be seen as an acute treatment, which is sort of like the opposite of a conservative treatment. Acute treatments tend to be more evasive, more error-prone and possibly more effective under the hands of specialists.

A typical acute treatment in medicine is surgery. Prior to going under the scalpel, a conservative treatment is often advised by the doctors. For instance, if the tonsils are under inflammation the doctor will advise some conservative treatment, like anti-inflammatories or antimicrobials. Should the things do not get better surgery is used to remove the tonsils.

Equally, if a friend of mine was obese I would recommend him a conservative treatment, like do some diet. I would not personally perform liposuction on him! If I were to suggest him liposuction I would forward him to a specialist.

Same with this girl; she's got her serotonin receptors burned out, so let her take a rest. Giving her a treatment that especially involves serotonin agonists as well as MAOIs (like aya) might not be the best of the ideas especially if the prospective healer is amature.

I had been tempted to "cure" a schizo friend of mine with mushrooms in the past, well after some thought I dispelled the idea. He was already a liability, I wouldn't want to do the things worse.
