A strong immune system is your body’s first line of defense against infections, viruses, and chronic diseases. While lifestyle factors like sleep, nutrition, and exercise play crucial roles, certain herbs can give your immunity a powerful boost. In this guide, we’ll explore the best herbs for immune support, backed by both traditional medicine and modern science. Whether you’re looking to prevent seasonal colds, recover faster from illness, or maintain year-round wellness, these natural remedies can help.
How Herbs Strengthen Immunity
Before diving into specific herbs, it’s important to understand how they work:
