Homeopathic medicines are selected on the basis of personality traits on an organism. Psychological makeup of that individual is most important part of his personality. To understand his psychological makeup, face to face conversation is most important.
Homeopaths are trained for face reading and understanding expressions of the patient by body language. Face to face conversation helps to build good doctor-patient relationship and develops connect between them.
Also video consultation helps for the patient to feel more trust in doctor to tell in details about his personal problems and issues. If a patient is prescribed without video conversation, many a times most important information may be missed and which makes medicinal selection more difficult.
That is the reason why we prefer video consultation.
In some simple acute cases, it is possible to prescribe without video consultation but while treating chronic complaints, video consultation is suggested.
