Tag: Curled dock

Over 15 species of dock exist worldwide, many considered common weeds, yet the young leaves of certain varieties are surprisingly edible. Dock leaves are edible, but they contain oxalic acid, so foragers must take precautions and consume them in moderation.

Studies have shown that certain *Rumex* species, like sorrel, can contain very high levels of total oxalates, sometimes exceeding 900 mg per 100g of wet matter, confirming that *Rumex* is high in oxalates. This natural compound is the source of the distinctive sour, tangy flavor found in edible varieties.
