Garlic is another culinary favorite that contains strong antiviral properties. Studies show that garlic extract and its compounds diallyl trisulfide, allicin, and ajoene, are active against the common cold, Influenza A and B, Herpes Simplex, viral pneumonia, and rotavirus.
One particular study involved 146 participants over 12 weeks. Half took a daily garlic supplement and the other a placebo. The placebo group had 65 cases of the common cold, whereas those who took garlic, only had 24. Overall, those who took garlic had fewer days of illness compared to the placebo group.
You can infuse sautéed garlic into all kinds of dishes, ranging from soups and stews to casseroles and snacks.
3. Star Anise
Star anise is a spice made from the fruit of the Chinese evergreen tree and is aptly named after its star-like shape. It contains many health-promoting compounds, but one in particular called shikimic acid is so effective as an antiviral that it is one of the main active ingredients in Tamiflu, a popular medication for influenza.
Star anise works well with white meats like chicken, and also makes a great ingredient in marinades and stews. Add it liberally.
4. Coconut Oil
If you’re starting to feel as though there’s nothing coconut oil cannot do – you have a point. Coconut oil contains both monolaurin and lauric acid, which have demonstrated in studies to be able to disintegrate the outer membrane of pathogens, while also interfering with their ability to assemble and multiply inside your body.
Most of us know the possibilities of coconut oil in cooking. You can use it in place of any oil, and also in things like baked goods and sweet treats.
