 any of my colleagues that use hyssop regularly. So I'm kind of punching above my weight when it comes to hyssop. But they used it in the Bible to cleanse people, and God only knows what they meant. Today, don't they call that oregano? Okay. That's what oregano is today, I believe. Hyssop. But they use the same thing. Well, it's a semi-evergreen perennial in the mint family.
