Garlic
Garlic is antibiotic, antimicrobial, and antibacterial, says Clinical Herbalist and New York City-based founder of Urban Herbalist Steve Sietos. “When you have yellow or green phlegm, reach for that garlic. It’s highly anti-viral, immune stimulating, and it’ll kill any upper respiratory infections,” he says. Garlic is a great medicine for yeast infections and urinary tract infections too, according to research from the Birla Institute of Technology and Sciences in India.
To use it as an elixir, take a clove of fresh garlic. Press or chop it and let it sit for 15 minutes. When the garlic reacts with air, a chemical reaction transforms the clove into a powerful antibiotic, says Sietos, who also treats pets with herbs. He says that if you spread garlic and olive oil on a piece of bread or mix it with olive oil, it’ll knock out any upper respiratory infections.
