Arnica is a very good medicine for such condition.. kindly consult with more details for a proper prescription

Hello  , Homeopathic medicines will surely help your  brother in law. We can hope for the best.

In such conditions Arnica and Opium are the first two medicines used. But still need more details of the case and especially current status of the patient, vitals, excretion etc. If you are trying to self medicate the patient then I will. Suggest not to. Consult a doctor and take proper advice.

we require more details such as is it coma vigil, pupil contracted , skin cold , cause of his illness either is it mental or physical and many more. because their are many medicines in homeopathy for coma we prescribe medicine after complete case taking online consultation available. as you asking about Arnica_ we prescribe arnica if any history of head injury is present or any cerebral congestion is present, for details plz contact.

Pl consult the homoeopathic doctors at Faculty of Homoeopathy, London.

Need detailed case history.

Few more details required please

It will be better if you send reports and current prescription. Arnica in this type of case is very useful but the potency you mentioned can not be used in a coma patient. Other potency can be applied keeping medical records in view.
