I live out in the country, and find wild herbs pretty often. I only harvest the herbs I can recognize. So far this year I've found chamomile, dill, rosemary, and wild mints. I agree with what a lot of other people are saying about being carefully harvesting in the wild. Always try to identify the herb as closely as possible. On a side note, I have personally found that the local wild rose hips taste a lot better than the cultivated ones I normally have.
