Hi- I realize that this is probably too far for you, but Henry Brockman comes to the Evanston farmer's market with his sister Teresa. His sister brings all kinds of fresh organic herbs every Saturday, and I am sure that chamomile is one of the ones she brings. I bet that you can get some at the Green City Market too. I am not familiar with the farmer's markets in the Wicker Park area, but maybe you can find it at one of the markets there. Hope this helps, Nancy
