Growing on the mountains, Arnica may be said to possess a native affinity to the effects of falls. As its German name, Fallkraut, attests, its value as a vulnerary has been known from remote times. It may be said to be the traumatic par excellence. Trauma in all its varieties and effects, recent and remote, is met by Arnica as by no other single drug, and the provings bring out the appropriateness of the remedy in the symptoms it causes. Tumours in many parts, following injury, have been cured by Arnica, including scirrhous tumours of the breast. Nervous affections as chorea after falls. It is suited to plethoric red-faced persons; "Arnica is particularly adapted to sanguine, plethoric persons, with lively complexions and disposed to cerebral congestion. It acts but feebly on persons who are positively debilitated, with impoverished blood and soft flesh. This may be the reason why it is eaten with impunity by herbivorous animals as Linneus remarks" (Teste). It is suited to persons who are extremely sensitive to mechanical injuries, and who feel the effects of them long after; persons easily made train-sick or sea-sick. Patients complain that the bed is hard no matter how soft it may be. Arn. corresponds to the effects of violent cough or sneezing; the child cries before cough comes on (or with the cough) in whooping-cough. Chronic bronchitis when patients have bruised, weak aching in the chest, or great sensitiveness of the chest on exertion, or walking. Allied to wounds are haemorrhages, and Arnica causes and cures haemorrhages of many kinds: dilatation and rupture of small blood-vessels. Vomiting, coughing, purging, accompanied by streaks of blood in ejecta; extravasation of blood into the conjunctiva as in whooping-cough. Haemorrhages into the tissues of internal organs or the skin. An odd symptom of Arnica is "coldness of the nose." A case of facial (left) neuralgia, face swollen, dark red, very painful to touch, was cured with Arnica (radix), the guiding symptom being "cold nose." Patient had bitter taste; was very excitable, and < at night. Ussher notes that the local use of Arnica produced an extraordinary growth of hair on a limb. This suggested the use of an oil mixed with Arn. 1x in a case of baldness, which was followed with marked success. Arn. affects the left upper extremity and the right chest. There is a putridity in connection with Arnica excretions, as with Baptis., which it resembles in typhoid conditions: putrid breath; fetid sweat. With Arnica there is apt to be incessant passing of stool and urine in these states. Nash gives the following as "leaders": "Stupor, with involuntary discharge of faeces and urine." "Fears being touched or struck by those coming near him." Putrid smell from mouth." "Bruised, sore feeling in uterine region; cannot walk erect." "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." "Suddenness" is a feature of Arn. pains and action. P. P. Wells relates a cure of double pleuro-pneumonia in a child with sudden stabbing pains on both sides of the chest almost preventing breathing. Arnica instantly caused a violent aggravation, the next instant relief was perfect, and the child fell asleep breathing naturally. I once ran a piece of wire into the tip of one of my fingers, causing paralysing pain. I applied Arn. 1x at once, and the pain was better instantly—seeming to be wiped out from the point of injury up the arm. There is < in damp, cold weather with Arnica, which is included by Grauvogl among the remedies suited to the hydrogenoid constitution (comp. Baryt. c.). Motion and exertion <. (Bruised, aching sensation in chest on walking.) > Lying down, and lying with head low; but < lying on left side. Arnica should not be used externally where there is broken skin. For torn and lacerated wounds Calendula must be used locally.
