There is no permanent cure for allergic cold and cough, but you can get long-term relief by identifying and avoiding triggers like dust, pollen, smoke, and pet hair. Keeping your home dust-free, using masks when exposed to allergens, and maintaining good hydration can help. Regular use of doctor-prescribed anti-allergy medicines or nasal sprays, and in some cases allergy immunotherapy (allergy shots), can greatly reduce symptoms over time. Consult an allergy specialist for a personalised long-term plan.

A cough lasting 6 months should not be self-treated, even with Ayurveda. It is important to consult a qualified Ayurvedic doctor before starting treatment. Also, get evaluated by a physician to rule out conditions like asthma, GERD, or TB, as treating the cause is essential for long-term relief.
