Garden sorrel
Rumex acetosa
A perennial lemon-acid green (oxalic acid). French sorrel (R. scutatus) is a milder leaf. A handful in soup is classic; daily kilos of oxalic greens are not a strategy.

What it is
A perennial lemon-acid green (oxalic acid). French sorrel (R. scutatus) is a milder leaf. A handful in soup is classic; daily kilos of oxalic greens are not a strategy.
From the existing encyclopedia
Sorrel shows up in regional spice blends, apothecary tea chests, and slow-cooked pots where aroma matters as much as flavor. Store in a cool, dark cupboard in an airtight jar; label with purchase date. Works alongside green tea or ginger in everyday beverage rotation. When substituting dried Sorrel for fresh, use about one-third the volume and bloom in fat or hot water before adding acid or dairy.
Edible portions
- leaves
Absence of a portion from this list means it is not treated as food here — not that every other part is toxic.
Growing
- Climate. 4–8 perennial
- Light. Sun to part shade
- Soil. Moist, rich, even slightly acid
- Planting. One clump is plenty. Remove flower stalks to keep leaves.
- Harvest. Spring and fall; summer leaves are tougher.
Preparation and culinary uses
- Sorrel soup
- Sauce for fish
- Mixed salad in small amounts
Nutrition and compounds
- Vitamins (qualitative, well-known associations). vitamin C — not milligram values.
AAA interpretation Food first. These associations explain why a plant shows up in a nutrient conversation — they are not a supplement shopping list.
Safety
- Oxalic acid: food amounts in mixed diets are the use. People with a history of oxalate kidney stones should treat high-oxalate greens as a food-pattern question, not a web protocol.

Honest incompleteness is preferred to fabricated completeness. If a section is missing, no record for it is attached here — not a claim that the plant lacks that characteristic, and not that it was omitted as a secret.
