For long-term relief from chronic sinusitis, Ayurveda focuses on balancing Kapha and Vata doshas. Key recommendations include: 1. Nasya therapy: Daily nasal drops of Anu Taila or Shadbindu Taila clear congestion and strengthen nasal passages. 2. Herbal remedies: Haridra Khanda helps reduce allergic sensitivity, while Trikatu churna (ginger, black pepper, long pepper) reduces mucus. For the yellow cough, herbs like Vasa (Adhatoda vasica) and Tulsi are highly beneficial. 3. Steam inhalation with eucalyptus oil relieves blockage. Avoid cold, heavy foods and drink warm water. Please consult a qualified Ayurvedic physician to tailor these remedies safely to your specific constitution.
