Poke.
Poke is a roadside weed whose very young shoots are a traditional Southern green after repeated boiling. The root and mature plant are irritant and are not food.

What Poke is, and what it does.
- Does it work
- This suits people interested in traditional Appalachian foodways who can identify the plant and prepare the young shoots by boiling and draining twice.
- How much to take
- No dose figure is on record, and none should be inferred. Traditional food use is a portion of twice boiled young shoots, and never the root.
- Time to feel it
- As a prepared spring green there's nothing to wait for beyond the meal. Nobody has measured a supplement style time to effect for this plant.
- The first dose
- Properly prepared young shoots eat like any cooked green. Poorly prepared material or root brings vomiting and watery stool within hours, which is the saponins.
- With regular use
- There's no long term human research here. Traditional use is seasonal and limited to spring shoots, when saponin content in the plant is at its lowest.
- How well tolerated
- This is a genuine caution. Root and mature plant appear in clinical toxicology references as causes of poisoning, most often from root dug up alongside greens.
- How it feels
- Twice boiled young shoots taste like a strong spinach. Material from the root or the mature plant is felt as burning and stomach upset, not as a benefit.
- The overlooked benefit
- The double boil isn't superstition. The irritant saponins dissolve in water, so they leave with it, which is exactly why the water gets thrown away each time.
The proof, claim by claim.
These words describe the research, not the molecule's worth. Research strength is how much work stands behind one claim, and it is never a product score.

Why these belong in the same formula. Each row says what the basis is, from settled biochemistry through to a trial that measured the pair.
Pokeweed greens carry oxalate and triterpenoid saponins, both of which bind divalent minerals in the gut. Traditional preparation boils the shoots in several changes of water, which leaches much of this out along with the irritant fraction. Eating them alongside an iron supplement lowers how much of that iron is taken up.
Oxalate binds calcium into an insoluble salt in the gut, which is the same reason spinach calcium is poorly available. Poke greens sit in that same category of high-oxalate leaves. Anyone with a history of oxalate kidney stones should not be eating them at all.
Poke root and berry are strongly purgative, and anything that speeds transit shortens the window in which other nutrients and medicines are absorbed. Layering a bulk laxative on top compounds that. This is a caution about the combination rather than a benefit.
Repeated vomiting or watery stool strips potassium and sodium. Poke root causes both at doses that are not far above the traditional ones. The relevant point is not that potassium pairs well with poke, it is that poke creates the deficit in the first place, which is one of the reasons the root is not used as a supplement.
Nothing specific on file for Poke. Match the label to the daily amount above, and tell your doctor what you take.
Not medical advice. Show the label to your pharmacist.What Poke actually does.
This plant contains saponin compounds that directly irritate the gut lining, which is why the root and mature plant cause vomiting and watery stool.
Saponin levels rise sharply as the season goes on and are highest in the root and mature stem, which is why traditional food use is limited to very young shoots only, never the root.
Pokeweed mitogen is a protein from this plant that labs use to trigger immune cell division in cell culture. It's a lab reagent, and what it does in a dish says nothing about what eating the plant does in a person.
Traditional preparation of young shoots involves boiling in at least two changes of water, discarding the water each time, because the irritant saponins dissolve in water and get removed with it.
Where Poke comes from.
A tall roadside weed. The young shoots are a Southern US food if you boil and drain them twice, and the root is the part that puts people in hospital.
Made from a plant. What ends up in the capsule tracks the harvest, so batch testing and a stated marker matter more here than with a made molecule.
A large perennial weed of eastern North America, spreading readily on disturbed ground
Food preparation leaches the water-soluble saponins out of young shoots and discards them, while tinctures do the opposite and concentrate them
Cooked greens are a regional food, and dilute tinctures appear in homeopathic dispensing. Neither route is used as a conventional supplement ingredient
