Another use of the berries is as a natural dye for arts and handicrafts.
Also the green berries of some of the Central American congeners were used
as laundry soap because of the abundant saponines the unripe berries
contain.

*Toxicity:* All parts of common pokeweed are toxic to humans, pets and
livestock. Roots are the most poisonous, leaves and stems are intermediate
in toxicity (toxicity increases with maturity), and berries are the least
toxic. Since common pokeweed is not very palatable, most animals avoid
eating it unless little else is available, or if it is in contaminated hay.
Horses, sheep and cattle have been poisoned by eating fresh leaves or green
fodder, and pigs have been poisoned by eating the roots. Children are most
frequently poisoned by eating raw berries. Infants are especially sensitive
and have died from eating only a few raw berries. Although boiled young
shoots have been eaten as greens and berries cooked in pie, ingestion of
any part of the plant cannot be recommended. Adults have been poisoned,
sometimes fatally, by eating improperly prepared leaves and shoots,
especially if part of the root is harvested with the shoot, and by
mistaking the root for an edible tuber. Research with humans has also shown
that common pokeweed can cause mutations (possibly leading to cancer) and
birth defects. Since the juice of pokeweed can be absorbed through the
skin, contact of plant parts with bare skin should be avoided.
Symptoms of poisoning from common pokeweed include a burning sensation in
the mouth, salivation, gastrointestinal cramps, vomiting and bloody
diarrhea. Most people and animals recover within 1 to 2 days if only small
quantities are eaten. If large quantities are consumed, more severe
symptoms can occur, such as anemia, altered heart rate and respiration,
convulsions and death from respiratory failure. The primary toxic compounds
are thought to be oxalic acid, saponins (phytolaccotoxin and
phytolaccigenin) and an alkaloid (phytolaccin).

I enjoy reading about the restoration challenges from our colleagues on the
East Coast; especially when the discussion involves your natives that, as
in the case of pokeweed, are newly emerging invasives we are expending
resources on to control here.  Observing the rapid spread of pokeweed in
the Portland (Oregon) Metro region and its significant underground biomass,
I have no doubt that it could be a strong competitor against whatever
bamboo you’re dealing with (*Phyllostachys *sp*.*?).

Also, when I began researching the threat to human health from pokeweed a
couple years back, I could find only one *documented* instance of a
fatality due to ingestion.  Does anyone from pokeweed’s native range have
any other information, anecdotal or otherwise, to support or refute the
notion that pokeweed is a significant threat to human health?

Our native pokeweed is a beautiful plant that can rival bamboo in size and
stature on a good site. The spring greens were often cooked and eaten in
Appalachia, but the mature foliage, berries and roots especially, are
highly toxic. Kids will sometimes eat the attractive and juicy black
berries or use them to make “ink” as I did as a child. Fortunately the
berries are not highly toxic, but I wonder if planting something that is
poisonous will send up some red flags?
As nasty as garlic mustard is, I would not want to see it replaced by
poison ivy, native or not. Pokeweed is only poisonous if ingested.

*Subject: Bamboo Control with native pokeweed**

Anacostia Watershed Society treated a bamboo patch at Magruder Woods in
Hyattsville, Maryland, several years ago. Next year all the bamboo was
still dead. However, the following year the patch was covered with new
bamboo shoots. Last year and the year before I observed that the bamboo was
gone. At the Fall conference of the Maryland Native Plant Society in Towson
on September 29, 2012 I asked Jorge Bogantes with AWS how they did this. He
told me that they successfully used native American Pokeweed. AWS found out
that about 5% of the bamboo was not killed by the pokeweed and had to be
cut down.

I suggest we experiment this year with controlling bamboo patches we have
cut down this year with pokeweed. We can go out soon to the open space
habitats where we are controlling bamboo and identify which ones have
pokeweed? Then we can treat half of the patches but leave the other half
alone and see if resurgent pokeweed outcompetes the bamboo. The bamboo may
need one year foliar treatment for the pokeweed to work.

Hi Marc,

After I sprayed the bamboo we planted trees and then noticed a resurgence
of pokeweed which I know is weedy. So I just left it alone and it actually
inhibited the bamboo from massively regrowing. I know I just have to
control (with machetes) of the shoots that have made it to grow tall.

In some cases nature can help you if you know how to play with it.
Especially the aggresive native plants ;)

Thanks,

Jorge

I can come late in October for the bamboo. Anacostia Watershed Society
spread out the native poke weed over bamboo that had come back after being
treated a year or two before at Magruder Woods. It outcompeted most of the
shoots. We may want to try this as an experiment in the Spring for any that
survive the spraying. Jorge, would you like to describe and share this poke
weed project?
