Everything You Need to Know About Herbal Immune Stimulants, Immunomodulators & Antimicrobial Herbs

Curious how herbal remedies can help strengthen your immune system and ease those pesky cold and flu symptoms? When I first dove into herbalism over 30 years ago, I made it my mission to discover how herbs could support the immune system. This knowledge has kept my family and me healthier through the fall and winter seasons. And when we do catch something, we recover faster. Learning about herbs for immune support has truly paid off!

The secret to immune support lies in understanding the difference between tonic herbs (taken daily to prevent illness) and acute remedies (used to tackle active infections). This distinction is often overlooked in herbal education, but is essential to mastering herbal immunity. Timing and dosage are also key—immune stimulants and antimicrobials should be taken at least five times a day during an infection. Many people don’t take enough for the herbs to work effectively!

I encourage you to explore the various categories of immune-supportive herbs and choose three medicinal herbs or mushrooms to get acquainted with in each class. Once you’ve bonded with your new herbal allies, browse through our immune-boosting recipes to gear up for cold and flu season.
