Elderberries must be cooked before eating. Raw or unripe berries
Elderberries must be cooked before eating. Raw or unripe berries, and all leaves, stems and roots, are toxic; only fully ripe, cooked berries are safe.
Well established A person has checked it against its sources. This one is about eating safely, not how the plant grows. The planner suggests it.
How it works
The plant holds cyanogenic glycosides, highest in the unripe fruit, leaves, stems and roots and lower in ripe fruit. Eaten raw they release cyanide in the gut and cause nausea, vomiting and diarrhoea; cooking ripe berries drives off and inactivates the compound, which is why cooked elderberry (syrup, wine, jelly) is a traditional food while the raw plant is not.
What to do about it
Eat only fully ripe berries, and only after cooking. Never eat raw berries, unripe green berries, or any leaves, stems or roots.
How much it matters: Not quantified as a threshold dose. The source gives the hazard, the toxic parts and the ripe/ unripe gradient, and rates ingestion "nausea, vomiting, diarrhea, coma", a qualitative caution with no stated gram figure, so none is given here.
The evidence
Evidence: checked against 2 sources in the research-based literature.
The 2 sources
Ingestion can cause nausea, vomiting, diarrhea, coma. Unripe fruits are much more toxic than fully ripe fruits. Cooking helps inactivate the cyanogenic glycoside.
Raw elderberries, including the stems, leaves, seeds and flowers, contain naturally occurring compounds that can release cyanide during digestion

How we grade evidence
- Well established
- The rule names its mechanism and is settled, by sources a person has read and checked or by plain arithmetic and geometry.
- Promising
- The mechanism is named and the literature backs it. A few questions are still open.
- A good hunch
- Plausible by its mechanism, but field studies are thin, so treat it as a lean.
- Contested
- The evidence points both ways, or no study has tested it, so the planner does not enforce it.
- Refuted
- The claim did not survive its sources. It is kept so the folklore can be answered.
