Rubus villosus

Also called bramble, cloudberry, dewberry, goutberry, high blackberry and thimbleberry. Blackberry is a perennial, trailing plant which grows best in dry soil. It has slender branches with sharp, recurved prickles. The leaves are doubly serrated with fine hairs. White, five-petaled flowers bloom from June to September. The familiar fruit takes the form of an aggregate of black drupelets.

The leaves and roots of the blackberry plant are astringent and tonic, and are a well known treatment for diarrhea. Prolonged use of the tea is good for enteritis, chronic appendicitis and leucorrhea, and may also have an expectorant effect. One ancient remedy for bleeding gums is to chew on the leaves of the blackberry plant.
