Bruce you need to be cautious of this. Poke Salad is another name for Pokeberry which is a poisonous berry. I would advise nobody to knowingly add this to their wine. Are you certain it was pokeberry? Here is a picture of it.
All parts of pokeweed are toxic including the raw aboveground leaves sprouting in the early spring<SUP id=cite_ref-2 =reference>[3]</SUP>. The poisonous principles are found in highest concentrations in the rootstock, less in the mature leaves and stems, and least in the fruits. (Green fruits are slightly more toxic) Young leaves, if collected before acquiring a red color, are edible if boiled for 5 minutes, rinsed, and reboiled. Berries are toxic when raw but cooked juice is edible (the seeds remain toxic after cooking). However, it may be difficult to identify exactly when leaves have no red color whatsoever; an incorrect picking may result in a poisoning.
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, and is occasionally available commercially.<SUP id=cite_ref-3 =reference>[4]</SUP> Many authorities advise against eating pokeweed even after thrice boiling, as traces of the toxin may still remain. It should never be eaten uncooked. For many decades, poke salad has been a staple of southern U.S. cuisine, despite campaigns by doctors who believed pokeweed remained toxic even after being boiled. The lingering cultural significance of Poke salad can be found in the 1969 hit song "Polk Salad Annie," written and performed by Tony Joe White, and famously covered by Elvis Presley, as well as other bands including the El Orbits of Houston, Texas. Pokeberry juice is added to other juices for jelly by those who believe it can relieve the pain of arthritis. There are currently four known poke sallet festivals held annually. They are in Gainesboro, Tennessee; Blanchard, Louisiana; Harlan, Kentucky; and, Arab, Alabama.<BR clear=left>
Since pioneer times, pokeweed has been used as a folk remedy to treat many ailments. It can be applied topically or taken internally. Topical treatments have been used for acne and other ailments. Internal treatments include tonsillitis, swollen glands and weight loss. Grated pokeroot was used by Native Americans as a poultice to treat inflammations and rashes of the breast. Independent researchers are investigating phytolacca's use in treating AIDS and cancer patients. Especially to those who have not been properly trained in its use, pokeweed should be considered dangerous and possibly deadly.
Ingestion of poisonous parts of the plant may cause severe stomach cramping, nausea with persistent diarrhea and vomiting, sometimes bloody, slow and difficult breathing, weakness, spasms, hypertension, severe convulsions, and death. However, consuming fewer than 10 uncooked berries is generally harmless to adults. Several investigators have reported deaths in children following the ingestion of uncooked berries or pokeberry juice. Severe poisonings have been reported in adults who ingested mature pokeweed leaves and following the ingestion of tea brewed from one-half teaspoonful of powdered pokeroot.
Pokeweed berries yield a red ink or dye, which was once used by aboriginal Americans to decorate their horses. Many letters written home during the American Civil War were written in pokeberry ink; the writing in these surviving letters appears brown. The red juice has also been used to symbolize blood, as in the anti-slavery protest of Benjamin Lay. A rich brown dye can be made by soaking fabrics in fermenting berries in a hollowed-out pumpkin.
Some pokeweeds are also grown as ornamental plants, mainly for their attractive berries; a number of cultivars have been selected for larger fruit panicles.
Pokeweeds are used as food plants by the larvae of some Lepidoptera species including Giant Leopard Moth.
