*Allium cepa covers more symptoms of common cold than any other remedy, as the well-known effect of onions in producing tears would suggest. It will cure a large proportion of cases of cold in the head, but the conditions which most particularly indicate it are: Cough, or cold, or headache worse in warm room, better in open air, worse again on returning to warm room. It causes burning of eyelids, nose, mouth, throat, bladder, skin. Inflammation and increased secretion of mucous membranes: neuralgic pains like a *long thread, in face, head, neck, and elsewhere, worse evening, towards ear from deep within head. The toothache of *Cepa is better by cold air or cold washing. It is suited to traumatic neuritis. Hurts do not heal. The feet are easily galled by walking. It was recommended by Dioscorides as a remedy for this condition, and homoeopathy has confirmed his observation. Desire for raw onions is an indication for it. Thread-like pains are common in various parts and are characteristic of *Cepa. Thread-like pains in face. Left-side facial paralysis has been cured by *Cepa. The cough of *Cepa is caused by tickling in larynx, constant inclination to hack in order to relieve it. It has cured violent catarrhal laryngitis, hoarse cough with feeling as if it would split and tear the larynx, causing watering of eyes. Cough from inhaling cold air. *Cepa has yawning and drowsiness. A raw onion eaten just before going to bed is a popular remedy for sleeplessness. *Cepa is left-side medicine primarily.

Damp cold wind and weather causes colds and toothache. But cold water and open air better, warm room worse. Picking or sucking teeth better toothache. Eyes sensitive to touch.
