Eat it: Oregano is rich in caffeic acid, quercitin, and rosmarinic acid, all components that combat depression, fatigue, and anxiety.
Grow it: Oregano, like most herbs, is easy to grow. Look for a seedling at a local nursery, pot it, and just water as needed, leaving the soil on the dry side. It thrives better in containers, but make sure your pot is fairly large—at least 12 inches across—as this plant can grow pretty quickly.
