Why you need to use dried herbs instead of fresh herbs:
The reason has to do with lovely little bacteria spores known as Clostridium botulinum. If that name sounds familiar, it’s probably because you’ve heard of the condition it causes in humans: botulism. These spores thrive in certain foods when not exposed to oxygen. Oil is one of those foods. The thing about fresh herbs is that they contain water, and water promotes growth of the C. Botulinum. Do you know what doesn’t contain a lot of water? That’s right, dried herbs.
