The shiny, purple black berries of pokeweed can be very enticing to look at. Upon crushing a berry, you will see a purple-pink juice and lots of tiny dark seeds. The poisons in the plant are called phytolaccatoxin and phytolaccigenin, and are most concentrated in the roots, followed by the leaves and stems. Smaller amounts are found in the fruit and seeds, and there have been confirmed fatalities from eating the berries. Although you may find a recipe or two for pokeberry jam, and while some people do consume the cooked berries, my advice would be to avoid pokeweed altogether.
