Tulsi is considered one of the most purifying Ayurvedic herbs. When it comes to colds and flus, tulsi can help reduce headaches and fevers, relieve congestion, and support digestion. “Mildly warming, tulsi is known for soothing the nerves, supporting healthy emotions, and enhancing mental clarity,” Carlson says. “It’s also a great tea when going through rough times in life.” Carlson recommends that people fighting the flu try drinking one or two cups of tulsi a day, and that the original flavor is the best at helping fight a cold. Note: Carlson says to avoid tulsi during pregnancy or high-pitta conditions like acid reflux or hot flashes.
