Is your immune health up to par? Herbs can be much more than mere culinary seasonings. Eating a wide array of herbs and spices on a regular basis can go a long way toward strengthening your immune system and preventing illness.

In his new book, Upgrade Your Immunity with Herbs, Dr. Mercola offers a powerful toolkit for strengthening immunity and supporting health with 19 different medicinal herbs and spices, like ashwagandha, Echinacea and rhodiola, offering ways to use them in delicious and creative preparations for everything from teas and tonics to full meals.

And while there’s little question that diet is the most important contributor to immune health, Dr. Mercola also shares insight into other factors that play key roles, including:

• How to know how much water you need each day (you may be surprised).
• 11 ways to improve your sleep and your immunity.
• What vitamins and minerals your diet should include.
• The common (but easy-to-quit) habit that's linked to poor immune health.
