Or else this disease is caused by too much heat liver. This is called hypochonriasis. It is neccessary for the patient with Melancholia to be busy in work which keeps his heart contended and surrounded by people who give him respect and deep him happy. Small quantity of wine mixed with water should be given in moderation. Mirza Ghulam Ahmad Qadiani was using Tonic wine and opium for the same reason.
Melancholia is the change of thoughts from normal due to fear and disease.
In some patient this disease progesses so much that the patient thinks that he can tell the hidden things and often tells what is going to happen in future. Later it progresses to such an extent that he consider himself an angel. For a claimant of inspiration, if this is proved that he suffers from Hysteria, Melancholia or Epiepsy, then you don t need any other proof to reject his claim, because this is such a blow that his whole structure of truth is blown apart from is foundation. Hence the used of opium with medicines as treatment and not as intoxicant is not objectionable in any way. Every one of us, knowingly or unknowingly, has used opium at some stages.
