A runny nose, also known as rhinorrhea, refers to an excessive discharge of mucus from the nasal passages. It can be a response to infections, irritants, allergies, or other factors that cause the body to produce extra mucus to protect the respiratory system. It is often a symptom of conditions like the common cold, flu, sinus infections, or allergies.

Common Causes of a Runny Nose:

1. Viral Infections
   • Common cold, flu, or other upper respiratory infections caused by viruses.
2. Allergies (Allergic Rhinitis)
   • Exposure to allergens like pollen, dust mites, animal dander, or mold.
3. Environmental Irritants
   • Exposure to smoke, pollution, strong odors, or chemicals.
4. Sinusitis
   • Inflammation of the sinuses leading to mucus overproduction.
5. Changes in Weather
   • Cold or dry air can irritate the nasal passages, triggering mucus production.
6. Hormonal Changes
   • Pregnancy or other hormonal shifts can cause a runny nose.
7. Foreign Body
   • Small objects stuck in the nose, particularly common in children, may cause a unilateral runny nose.
8. Non-allergic Rhinitis
   • Sensitivity to irritants, temperature changes, or certain medications without an allergic trigger.

Homeopathic Miasmatic Causes of Runny Nose:

From a miasmatic perspective, a runny nose may be linked to various underlying tendencies:

• Psoric Miasm: Frequent colds or allergies leading to recurrent nasal discharge, often worse from changes in weather.
• Syphilitic Miasm: Discharges that are offensive or cause tissue destruction in more severe cases.
• Sycotic Miasm: Chronic, stubborn nasal discharge that persists, often with thick or colored mucus, worse in damp environments.
