Aconitum napellus: the sudden storm
Sudden fright, rapid attack, restless fear and the swing from burning heat to icy cold give Aconitum its forceful character in the homeopathic materia medica. The scene is set with a forceful attack of acute illness, where there is a tension that penetrates both psyche and soma. There is fear and anxiety with each complaint, no matter how small, the patient being restless. The tension is not an undercurrent; it is a fundamental condition.
I am describing a traditional homeopathic remedy picture: a way of bringing its mental and physical characteristics into focus. Sudden collapse or severe difficulty breathing needs urgent medical help; this portrait is not a guide to treating an acute emergency.
Fright and the fear of death
Ailments from fright define the onset; the fright may be a shock, a sight of an accident, or a sudden anger. The prover tosses about in bed, jumps out of bed, drives from place to place.
Her mental processes are faster than her physical ones. She can foresee the time and date of her death, is anxious about what is to come, is terrified of crossing the road and is easily startled. Music depresses her; the atmosphere is stifling. Now she is thrashing about in bed, then suddenly she goes limp, fainting or becoming catatonic. She can’t stand being touched, can’t stand being covered, can’t stand the pain.
Fear of death is also a fear of certain situations. The prover fears a crowd, fears crossing the street, fears subways. The contradiction of fear and movement is central.
Sweating is present with the anxiety. Heat aggravates the impatience; chill aggravates the sadness and the sensitivity.
Burning heat and icy cold
Heat and cold alternate, or occupy different territories in the same frame. The face burns red and swollen, the internal parts feel as if boiling water moves through them, breaking into a hot, dry rash or gooseflesh. At the same time, the hands and feet turn icy cold, numb, insensible. Tingling and formication crawl up the back and down the thighs. The cheeks may split the difference: one side red, the other pale. The patient feels the cold waves pass through him, yet the bed becomes intolerable; he wants to uncover. The tension of the vessels shows in a full, hard, bounding pulse that sometimes intermits; in the sudden flushing that turns to deathly pallor on rising.
Open air is better; a warm room is worse.
A chill from dry, cold winds, a draught of cold air, checked perspiration, or even a sudden exposure to intense sun and heat will throw the system into this acute state. The patient drinks cold water with unquenchable thirst, yet everything tastes bitter except water. He drinks, vomits, declaring he will die.
The senses overwhelmed
The senses are heightened or suppressed. The ears become attuned to melody and cacophony; the nose is sensitive, detecting powerful scents. Light is a barrage, the patient gazes with narrowed pupils, photophobia surging in the sunshine, photomania weighing upon the eyes.
Heat and acute inflammation march together with chill and wind. The eyes burn, redden, swelling; the tympanum flushes red and the ear hums or roars; the nose congests and the nostrils feel hot. Burning and tearing pain stitch through the orbits and the root of the nose, worse at night and during motion. Aching and rheumatic pain press behind the eyes.
Lachrymation flows, yet the conjunctiva and lids parch. The patient’s eyes aggravate in cold, dry wind; the coryza worsens. Stooping eases the eye pain. Sweat relieves the ear and eye pain. Difficulty opening the lids follows the inflammation.
Flow and blockage alternate. The nose gushes blood; coryza runs with white or burning discharge, or appears without discharge at all. Congestion presses at the root of the nose, sneezing following. Yet the inside of the nose dries out, the pupils contracting.
Tension, pain and the swing into weakness
Full, throbbing, hot, bursting sensation in the head. Vertex sensation of pulling the hair or standing it on end. Vertigo on rising or shaking the head. Throat constricts, burns and stings; tonsils swell dry. Dry, croupy cough hammers at night and after midnight.
Inspiration aggravates; expiration ameliorates. Muscles hold tension. The pains are pressing, as from a load, tearing, stinging, burning. Touch aggravates. The sound of music and general noise deepen the distress. Bending forward or rising from a stoop brings on vertigo, pain.
There is a pendulum swing from violent, feverish excitation to rapid collapse. The prover oscillates between a plethoric state and a sudden weakness of the joints. The internal pulsation matches the external heat. A vague sick feeling accompanies the fever. The mind is light, the sleep broken by fear. The evening and night deepen the suffering.
The plant and the sudden storm
The plant wears a helmet of violet-blue, a defensive architecture that mirrors the sudden, overwhelming nature of the attack.
As an image of the remedy, this is the state of a mind trapped in the moment of shock, unable to discharge the fright. The mind races, yet the body is exhausted.
Aconitum is the remedy of the sudden storm. The fright is the cause; the fear of death is the effect; the restlessness is the mind's attempt to escape a death it knows is coming.
