Oregano
This potent herb has many great benefits, but it’s best known for being very useful in killing viruses and bacteria. It has been proven to drastically reduce viral activity in just 15 minutes and is considered useful against herpes simplex type 1, rotavirus, and respiratory syncytial virus ( RSV ).
How to use it: To use it against a virus, you can drink the tea daily, add chopped oregano to your food, or take it dried and in capsules. To clean surfaces, mix a few drops of essential oil with water and shake thoroughly before spraying the surface and wiping it down.
Viruses aren’t the only reason to take oregano though. It also contains natural decongestants and antihistamines. When you take it daily, it can actually boost lung function, whether or not you’re sick.
