Although enough research has not been done, Tulsi can be used to manage conjunctivitis due to its anti-inflammatory, antibacterial, antiviral and antifungal properties. Tip: 1. Soak about a handful of Tulsi leaves in hot water for 10 mins. 2. Dip clean cotton pads in the water and place it over the eye. 3. Repeat this 3-4 times in a day.
