Tulsi, an Ayurvedic herb widely used in therapeutic herbal tea and true tea blends may be called Holy basil or Queen of the Herbs. Native to India and cultivated throughout Southeast Asia, it considered a foundational herb that often combined with black or green tea leaves or in an herbal blend with other health-promoting ingredients such as turmeric and ginger. It has a strong aroma and a flavor that can range from peppery to astringent. Tulsi tea may relieve symptoms of asthma, bronchiti, cold, congestion, cough, flu, sinusitis, sore throat, and similar ailments. To clear your sinuses, inhale the steam from a fresh cup of tea before you drink it.
