Himalaya Bresol Syrup is an effective remedy for allergic bronchitis and rhinitis, containing key ingredients like Holy Basil, Malabar Nut, and Turmeric. Holy Basil (Tulasi) has strong antihistaminic properties, helping protect against pollen-induced bronchospasms and reducing nitric oxide production, offering antioxidant benefits that aid in treating allergic respiratory disorders. Malabar Nut (Vasaka) is known for its mucolytic properties, thinning mucus and alleviating cough, while its alkaloids enhance bronchodilation, improving breathing in respiratory conditions. Turmeric (Haridra), rich in curcumin, helps block NF-kappa B, a protein complex linked to allergies and asthma, offering additional relief in respiratory issues.
