I'm not sure what the plant in the first pic is, other than a weed that grows in my yard too. The stuff climbing up the fence behind it is Virginia Creeper. The second pic looks like a wild blackberry to me.
Dried and powdered Goldenrod is antifungal and antimicrobial... take in small doses as you would a mild penicillin. Can affect gut bacteria also bitter as heck!
Dried Blackberry leaves can be effective in soothing cramps and indigestion, blossoms too. Of course, you can eat, preserve or just smell the berries!
thanks guys for the replies(: And thanks Chris for the uses. I need to learn that myself soon(might try that "Botany In a Day" book). I mistook that blackberry for nettle at first, ops ( I ate a few leaves ).
