Oxalates
Term
Oxalate anion structure
These are salts of oxalic acid, which are common in plants such as rhubarb, sorrel, spinach, tea leaves. Oxalates are found in leafy plants at about 0.2–1.3%, and in tea – about 2%. When oxalates enter the body, they combine into non-absorbable compounds that are excreted through the kidneys. Oxalates, constantly consumed with food, can promote the formation of kidney stones.
