Walk in the Park 1 Dogberry Pokeweed Inkberry

We called it Dogberry as kids, but we were idiots ....

from wikipdedia -
Young pokeweed leaves can be boiled three times to reduce the toxin, discarding the water after each boiling.

The result is known as poke salit, or poke salad.

The United States Declaration of Independence was written in fermented pokeberry juice (hence the common name 'inkberry').Many letters written home during the American Civil War were written in pokeberry ink....

When pokeweed is used as food, the water in which it is boiled must be discarded.

Clinical signs
In humans:
The eating of nonfatal quantities of poke, perhaps of the shoots, may cause retching or vomiting after two hours or more. These signs may be followed by dyspnea, perspiration, spasms, severe purging, prostration, tremors, watery diarrhea (often bloody) and, sometimes, convulsions. If a fatal quantity is eaten, perhaps including roots, the above signs are followed by paralysis of the respiratory organs and other narcotic effects, culminating in the death of the poisoned person.
