Wild Arum - Arum maculatum. Not to be confused with wild garlic although the young leaves can look very similar. All parts contain calcium oxalate which should not be consumed.
For anyone in the know:
I’m no expert & don’t know the biology of plants & cells,just their common uk names & uses to a degree.
However, I do consume a fair bit of stinging nettle soup when in season(home made).
I’m aware the stings contain oxalic acid & they are made safe by wafting over the fire or boiling.
So the question is..Are oxalic acid & calcium oxalate(in wild Arum)a similar compound/chemical or completely different?
Can one be boiled(soluble) or cooked out..the other not(insoluble).
