Below are the main rubriks (i.e strongest indications or symptoms) of Arnica in traditional homeopathic usage, not approved by the FDA.
Have you ever used Arnica? Yes No
Bruised, sore feeling all over; bed feels too hard.
Head, or head and face hot; body and extremities cold.
Ecchymoses; as from bruises.
Stupor; answers, then falls back into stupor (fevers).
Taste and eructations and stool like rotten eggs.
Recent and remote affections from injuries, especially contusions or blows.
Haemorrhages, the result of mechanical injuries.
Arnica Montana is the leading remedy for bruises and the results therefrom, and the symptoms -"Weakness, weariness, sensation as of being bruised." "Felt as if bruised over the whole body," as found in the provings, explain the reason and the many cures it has made, even in the high and highest potencies, of both acute and chronic affections. The result of trauma is another evidence of the truth of our law of cure. One of the best characteristics is "Everything on which he lies seems too hard" (Pyrogenium Pyrogen.); he must keep changing his position to get relief. This is because of the sensation of soreness as if bruised all over.
Baptisia Tinctoria Baptisia has -"Feels as if lying on a board; changes position bed feels so hard, makes him feel sore and bruised."
Phytolacca Decandra Phytolacca has- "Feels sore all over from head to foot; muscles sore and stiff, can hardly move without groaning."
Rhus toxicod. has -"Soreness in every muscle, which passes of during exercise; feels stiff and sore on first beginning to move."
Ruta Graveolens Ruta has -"All parts of the body on which he lies are painful as if bruised."
Here are five remedies which seem much alike, and other might be added, like Staphysagria Staphisagria, which has -All the limbs are sore as if bruised, and as if there were no strength in them, and
China China -"He is sore all over, in the joints, the bones, and the periosteum, as if they had been sprained, like a drawing, tearing, especially in the spine, the sacrum, the knees and thighs." Now to know thus far of these remedies would be of little use for therapeutic purposes, for it would be senseless to prescribe all of these remedies mixed together, and full as much so to prescribe one of them to the exclusion of all the rest without a good reason for so doing. Fortunately there is always a possibility of making choice between them, but it is not always easy. Take, for instance, Arnica and Baptisia Tinctoria Baptisia. Both have the symptom of sore bruised feeling. Both have feeling as if the bed were too hard. Both have stupor, from which they can be aroused, but fall quickly back into it again. Both have a dark streak running through the tongue.
I have met many such cases of diphtheria, and if prescribed early Phytolacca Decandra Phytolacca cures without the aid of any other remedy. Again if I found a patient with the sore, bruised sensation, who was brought into that condition by getting wet while perspiring, or by lying on damp ground, or between damp sheets, or from a strain of the muscles, Rhus Tox Rhus toxicodendron would be the remedy.
If in cases of actual injury I should find the bruise in the periosteum or bone, I should expect more benefit from Ruta Graveolens Ruta, which seems to be better also than Rhus Tox Rhus tox. in one kind of muscular strain, viz., strain of the ciliary muscles. I have often relieved sewing girls or students of pains in the eyes from this cause and have sometimes enabled them to lay off the glasses that had been prescribed by the opticians. It is much better to use Arnica Montana in a weakened power of accommodation than to try and compensate for it with artificial lenses. Of course where the impaired vision is purely optical this cannot be done.
So we might go on to draw the diagnostic symptoms between all the various remedies having a similar symptom if we had time and space. But it would not be the best thing to do, for every physician should get in the habit of doing this for himself.
In addition to all that has been said about the great value of the sore as if bruised sensation of Arnica Montana, it should always be remembered in affections, acute or chronic, which are the result of trauma. Among these are concussion; fracture of the skull with compression of the brain.
"Stupor with involuntary discharge of faeces and urine."
"Fears being struck or touched by those coming towards him."
"Putrid smell from the mouth."
"Offensive eructations or flatus, smelling like rotten eggs."
"Bruised sore feeling in uterine region, cannot walk erect."
"Soreness of parts after labor prevents haemorrhages or pyaemia."
"Cough; child cries before paroxysms, as if sore."
"While answering falls into a deep stupor before finishing."
"Head alone, or face alone, hot, rest of body cool."
"Many small boils, painful, one after another, extremely sore."
"Prevents suppuration and septicaemia and promotes absorption."
