Coryza is commonly referred to as a runny nose and is characterized by an acute inflammation of the mucous membranes of the nose. It frequently occurs concomitant to the ‘common cold’ and may be caused by a bacterial or viral infection, or may develop as an allergic reaction to diverse allergens such as dust, pollen and others.
The inflammation in the nasal cavity increases the secretion of mucous causing the typical symptom of the runny and congested nose. There may be nasal irritation, itching, burning, and sneezing. Oftentimes there is also some involvement of the eyes with redness, watering, swelling or itching. The inflammation may extend to the larynx, bronchi and throat, producing distinctive symptomatology there. Hence the patient may generally feel run down, may develop a cough, catarrh, frontal headache, lassitude and fatigue.
Some homeopathic remedies for coryza are:
