Can I use garlic leaf for cooking? I planted a garlic clove and now I have a nice garlic plant. The question is: Can I use the leaves to season food safely?

The leaves smell like garlic and I wonder if it's okay to use them dried, like oregano and other seasoning herbs. I don't know if will taste like garlic, or if it is dangerous to eat.
When we have had garlic in our garden I have used the garlic leaves. They do have a garlicky flavor but are milder than garlic cloves. I tend to use them more as I would chives or garlic chives as in addition to having the milder flavor than the cloves they make for a quite nice presentation.

Regarding drying them, I have never tried it. Off the top of my head I can't think of any reason not to dry them for later use but there may be issues that I just don't know about.
