Easiest way to remember this remedy is its peculiar combination between eye and nose discharges. Not every coryza state includes increased eye discharge, i.e. tears; if such discharge exists, then the two most probable remedies are Allium cepa and Euphrasia officinalis. The nose discharge of Allium cepa is acrid and excoriating while the tears are mild and harmless. In Euphrasia it is the opposite – arcid tears versus mild nose secretion.
This is easy to remember, especially with regards to Allium cepa, which is quite frequently indicated remedy for acute rhinitis. Acute rhinitis is accompanied by tears, just when we chop onion in the kitchen.
Next important symptom is the abundant secretion from the nose. It may just be dripping, excoriating the skin between lips and nose tip, and the upper lip.
Nose catarrh is usually accompanied by dull headache. The complaints are better outside in open air, and worse when returning into a warm room.
Usual timing for Allium cepa rhinitis is the early spring, when the weather is damp and windy.
Arum-t should be compared to Ammonium carbonicum, for these two remedies has similar pictures of coryza. Arum-t has same watery, acrid, excoriating nostrils discharge, and same obstinate obstruction. The nose is running fluently in spite of the obstruction.
But Arum patient is constantly picking at nose or boring it with finger, until it bleeds. Same is he doing with his lips, keeps picking at them until they bleed. The patient is biting his nails, until they bleed. In acute conditions these patients bore and pick raw and painful surfaces; they may scream with pain but do not stop.
There is general tendency to ulceration of mouth corners which crack, get sore and bleed.
This remedy should be used in high potency, above 30 C, and not to be repeated very often.
Camphora is the homeopathic antidote. It is also great remedy for interruption of acute cold. Patients are extremely chilly and yet refuse to be covered. They are also painfully sensitive to the slightest touch, and prostrated. All complaints are worse from cold air.
Nose is either stopped or running. The right nostril is more affected. Violent chills accompany the cold.
Camphora should be given at the commencement of the acute.
Damp and cold weather, and changes of weather from warm to cold and wet should be remembered as prodrome of Dulcamara’s coryza. Usually these patients have rheumatic complaints. They are intolerable to cold air because it completely obstructs their nose. Especially bad is when it rains.
The discharge is yellow, mucus, and makes crusts which may be bloody.
Euphrasia is well known remedy for eye affections. It has its use in coryza states, with reverse discharge characteristics to Allium cepa. The lacrymation of Euphrasia is acrid and profuse; the nose secretion is also profuse but mild. Warm windy weather aggravates the symptoms of coryza; warmth in general and the sunlight.
Eyes are watery, swimming in hot, acrid, smarting tears; with photophobia and gushing nose discharge. There is also cough, mostly in the morning, with abundant expectoration.
