What to do with Autumn Olive Leaves?

Hi, all!

QUESTION:
Are autumn olive LEAVES poisonous? Could I dry them to make a tea, or start a wild ferment with them for mead, or flavor kombucha with them?

BACKGROUND:
I recently took cuttings from my two autumn olive shrubs (red and gold berry varieties) and I stripped away lots of leaves in the process. I couldnt just mulch all of the leaves because they're so beautiful with their silver underbelly— they seem to just beg to be used in an elixir, but I cannot find any mention across the interwebs about using the leaves. I like fresh eating the berries and will experiment more with them this fall, but what about the leaves?

Yes you can eat them I've ate them before but they do not have much food value  or taste and tenderness
