Oil of oregano. This is my favorite pick for a medicinal herb. This stuff has amazing immune system benefits and antibiotic properties. We use it constantly in my house to wipe out colds and flues, it does the job every time! Capsules are the most convenient form, although you can purchase the oil and add it to beverages (Don’t expect it to taste good!)
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
