12 Indian Herbs That Boost Immunity Better Than Supplements

3. Tulsi (Holy Basil): Everyday Antiviral Herb

Tulsi—holy basil—has a place on many Indian windowsills and in countless home remedies for coughs and colds. It’s prized for antimicrobial and immune-supporting compounds and is a common ingredient in traditional kadha recipes. Practically, fresh tulsi leaves steeped with ginger, black pepper, and a touch of honey make a soothing tea that many families rely on during seasonal sniffles. Scientific reviews note tulsi’s broad antimicrobial and antioxidant profile, supporting its traditional use. For readers in North America, tulsi grows well in a pot, and organic dried tulsi is widely available. Use it regularly as a calming tea rather than a high-dose concentrate. Safety notes: tulsi is generally safe for most adults but could affect blood-thinning medications or interact with diabetes drugs, so check with your clinician if you take prescription treatments. Tulsi’s strength lies in gentle, daily use rather than aggressive short-term dosing.
