Airhead,
Yes on bloodroot - you can harvest it, dry it and sell it but the price has been so low lately it is hardly worth the time to mess with. Year before last I harvested some here and there while hunting seng (if it was easy to get to and not much out of my way) and ended up with about a 1/2 pound dry and got almost nothing for it.
I did not dig any blood root last year, except that one I dug to show in that pic.
I have heard that blood root juice can be used on skin cancers, but not sure about that.
On the best time to hunt seng, no doubt later in the fall is best time (around here mid sept the berries are nice and red) but later in fall the leaves turn yellow (late sept, first half of october). They sure are a lot easier to spot when they have yellow leaves and if/also red berries.
