I put camomile in the wort boil in my last beer, and it turned out great. Both Dogfish Head and Wolavers make a great Wildflower Wheat beer that is just 50/50 wheat and two row with wildflower honey, camomile, and saaz hops. I had about 1/4 lb of honey malt lying around that I tossed in there as well to complement the wildflower honey, and my batch turned out great. You don't get much of the camomile in the taste, but it really adds to the aroma of the beer.
I did 2 oz of the dried camomile flowers with 10 min left in the boil. I think I could have added just a bit more, maybe like 3 oz next time.
