The Arnica patient is one of shock and denial. There is a deep conviction that “there is nothing the matter with me,” even in the face of obvious trauma or serious injury. Clarke described this mental state as “a refusal to be helped,” where the person insists they are well while clearly suffering. Kent observed that the Arnica state reflects both physical and emotional bruising: shock after accidents, trauma, or surgery, and even long-standing emotional blows. Fear of being touched or approached is pronounced. Boericke noted fear of death, especially from heart failure, yet the patient feigns health. Dreams may be filled with frightening events, falls, and past injuries. There is often irritability with a desire to be left alone and strong aversion to consolation.
Sleep
Restless sleep characterised by tossing and turning. The patient may wake frequently, especially after trauma. Dreams often involve falling or the original injury reoccurring. Kent noted that sleep was disturbed by the sensation of the bed being too hard.
Dreams
Dreams of injury, falling, robbery, or past traumatic experiences. Sleep is anxious and broken. Clarke noted dreams that repeat real-life trauma events.
Generalities
Keynotes: bruised soreness, denial of illness, and worse from touch or movement. Complaints follow trauma, overexertion, or shock, whether physical or emotional. The bed feels too hard. Excellent for post-surgical healing, falls, accidents, and sports injuries.
Fever
Fever after injury, with coldness and soreness. Face may be hot while limbs are cold. Pulse is weak or rapid. Boericke described fevers where the patient says, “I am well,” despite obvious illness.
Chill Heat Sweat
Chilly with shivering, alternating with heat. Sweat may be cold or clammy. Perspiration follows effort or fright.
Head
A chief remedy for concussion, Arnica addresses both the acute and chronic consequences of head injury. Kent noted heaviness and dullness, with confusion and vertigo after blows. Head feels hot, bruised, and sore, as if it had been beaten. Clarke described a sensation of pressure inward, worse from movement. Post-concussion syndrome with memory problems, headache, and mood changes often respond well. The scalp may be tender to touch, and headaches appear after exertion, strain, or emotional shock.
Eyes
Black eyes (ecchymosis) from trauma are classic indications. Pupils may be dilated after concussion. There is pain, soreness, and bruising around the orbits. Hering noted retinal haemorrhage and aching of the eyeballs. Vision may be blurred after shock or head injury.
Ears
Ringing in the ears following trauma, especially after blows to the head or whiplash. Hearing may be impaired post-injury. Boericke mentions a sense of fullness or buzzing.
Nose
Epistaxis (nosebleed) following injury or strain, especially from overexertion. Clarke recorded bruised, sore sensation over the nasal bridge, often following trauma.
Face
Face is pale or blotchy, sometimes with cold sweat. There may be redness in spots, or it may alternate with pallor. Clarke noted twitching of facial muscles during fever or after injury. Injuries to the jaw or cheeks respond well.
Mouth
Mouth may be dry with bitter taste. Clarke described soreness of the tongue and bleeding gums after dental work or trauma. The tongue may feel heavy and bruised.
Teeth
Pain in teeth after trauma or extraction. Boericke mentioned loosening of teeth and soreness of gums. Pain is worse from chewing or clenching.
Throat
Soreness after straining the voice or swallowing bruised food. Clarke noted a raw, scraped sensation after injury. Often not a central sphere of action unless injured.
Chest
Chest feels bruised, sore, and heavy. Pain worsens with coughing or deep inspiration. Arnica is indicated after blunt trauma to the ribs or sternum. Kent noted that even the bed feels too hard, especially beneath the chest and shoulders.
Heart
Palpitations with fear or exertion. Clarke reported rapid, weak pulse after trauma or loss of blood. Arnica has an affinity for the myocardium in the aftermath of physical strain, overexertion, or emotional shock.
Respiration
Shortness of breath after injury to the chest or abdomen. Breathing is shallow due to soreness of the thoracic muscles. Clarke noted dry, hacking cough post-concussion or trauma.
Stomach
Loss of appetite with nausea after injury. Hering described vomiting of blood in cases of abdominal trauma. Aversion to food and fear of being fed, especially after shock or fright.
Abdomen
Abdominal bruising or soreness after a fall, blow, or surgery. Boericke described the abdomen as feeling hard and sensitive. Haemorrhagic tendency noted in abdominal organs, with distension.
Rectum
Painful haemorrhoids after childbirth or straining. Stool may be involuntary, especially after injury or during sleep. Kent emphasised the bruised soreness around the anus.
Urinary
Incontinence after fright or trauma. Clarke noted involuntary urination during sleep. Urine may be dark, even bloody, especially after injury to the abdomen or bladder.
Food
Aversion to meat and milk. Desire for sour things in some cases. Appetite diminished after trauma or fright.
Male
Testicular soreness or pain after injury. Kent observed contusions and bruised pains following trauma to the genitals. Erections may be suppressed after emotional or physical shock.
Female
Soreness and bruised sensation in the pelvic region, especially after labour or miscarriage. Arnica is invaluable for the postpartum period, particularly when there is a reluctance to be touched or helped. Clarke mentioned uterine haemorrhage after trauma.
Back
Back pain after falls, lifting, or blows. A leading remedy for spinal trauma or whiplash. Kent described bruised pain in the lumbar region and between the shoulder blades. Muscle stiffness and soreness dominate.
Extremities
Soreness, bruising, and lameness are hallmarks. Arnica is the premier remedy for trauma to soft tissues, including sprains, strains, and overexertion. Boericke remarked: “As if beaten.” Kent emphasised that the limbs may tremble or feel paralysed after injury. Cramps and contusions are common.
Skin
Bruises that form easily or remain for a long time. Subcutaneous bleeding, ecchymosis, and trauma-induced cellulitis. Clarke mentioned pustular eruptions in some cases. Wounds feel sore, and skin is tender to touch.
Arnica montana is a perennial flowering herb native to the mountains of Central and Southern Europe. The plant bears yellow, daisy-like flowers and has been used since ancient times in folk medicine for bruises, injuries, and muscular pain. The principal active compound, helenalin, is toxic in large amounts and has a marked effect on the circulatory and muscular systems.
Used externally in creams and gels for bruises, sprains, insect bites, and muscle soreness. Internally it is toxic and not recommended outside homeopathic use. It is a staple of herbal first-aid kits, especially in alpine and mountaineering cultures.
Proved by Samuel Hahnemann, and included in Materia Medica Pura (published c. 1811–1821). His provings confirmed its action on trauma, haemorrhage, and shock.

Bellis perennis: For deeper, visceral trauma and injuries to the abdomen or breast.
Ledum palustre: For puncture wounds, especially if coldness predominates.
Staphysagria: For surgical trauma and emotional insult, not physical bruising.
Complementary: Bellis perennis, Ruta, Hypericum

Arnica represents the body’s refusal to acknowledge injury—physical or emotional. The wounded warrior who says, “I’m fine,” despite bleeding and pain. The shock absorber of the Materia Medica, it brings comfort and rapid healing when the system is thrown out of alignment by trauma. It is the remedy of falls, blows, accidents, surgeries, emotional bruises, and overwork.
Always consider Arnica as the first remedy for any form of trauma—surgical, accidental, athletic, or emotional. Especially effective in 30C or 200C after falls or bruising. LM potencies useful in post-operative or prolonged trauma care. Use topically in low potency (e.g. 6X) for local application unless skin is broken.
