I do as needed. I have yarrow growing in my yard, which works well as a topical to stop bleeds. A few other things as well. One year when I couldn't garden, I bought both Midwest Foraging and Backyard Foraging. Amazing what grows in my yard, and the city calls them weeds! They require "noxious weeds" to be trimmed regularly. So I trim. Comfrey makes a great salve for lower back pain and would take over the yard anyway if I didn't beat it back occasionally.
