Rosemary
“Rosemary is highly antiviral and antibacterial,” Sietos says. “Everything you smell in that signature aroma is medicine.” How do you take this fragrant elixir? If you’re working with fresh rosemary, simmer it in water for 10 minutes and cool. Drink it three times a day until your cold is gone, Sietos recommends. If you’re working with dried rosemary, take a teaspoon and steep it in a cup of hot water to create a sipping tea.
