Allium Cepa (All-c.)
Watery and acrid nasal discharge which becomes worse in a warm room. Oppressed breathing. Tickling in larynx. The eyes are sensitive to light. Burning in nose, mouth, throat, bladder, and skin. Sneezing, especially when entering a warm room.
From cold damp winds; acrid water drops constantly burn like fire, excoriates the lips and wings of the nose, sneezing with constantly increasing frequency with profuse non-burning watering of the eyes.
Splitting laryngeal cough. Worse in a warm room and better in the open air.
Arsenicum sneezes in the open air and has not had the laryngeal symptoms of Allium.
Almost similar to Mercurius in its eye and nose symptoms but Mercurius has more distress in the frontal sinuses, has a tendency to perspire which gives no relief or even aggravates, and the discharge through profuse is not almost as watery as with Allium and not as thick as with Pulsatilla
