Oxalic acid has many uses, but it is widely used as a wood bleach because it removes stains without removing the natural color of the wood. It can be used on spots on furniture, like dark water marks, and it can be used to remove stains from larger areas of wood like floors and decks.
Oxalic acid, or oxalate, is a compound in many plant foods. In large quantities, it can inhibit the absorption of some nutrients. Learn more.

Answers to Frequently Asked Questions By Michael Liebman, Ph.D. What is calcium oxalate? What is the difference between calcium oxalate and “oxalate?” What is oxalic acid? Oxalic acid (chemical formula HOOC-COOH) is a strong organic acid which is widely distributed in nature in both plants and animals. However, plants contain more than animals. The name comes […]
Oxalates are compounds present in a wide variety of plant foods. Some health influencers tell us that they can cause kidney stones — and that they prevent your body from absorbing essential nutrients. But how warranted are those claims? Here’s what you need to know about oxalates, and whether to include foods that contain them in your diet.
Q: “Does Fermentation Reduce Oxalic Acid in Food?” A: “You bet.” With spring and summer gardens teaming with produce, more people have been interested in mineral inhibitors in vegetables. Last month I posted about the mineral inhibitor oxalic acid. The article is on the calcium site but the discussion applies equally to iron. Oxalic acid […]
Scientific name: Oxalis species Abundance: plentiful What: leaves, flowers, seedpods, tubers How: salad, seasoning Where: shady undergrowth When: spring, summer, fall, winter Nutritional Value: Vitamins A & C Dangers: Contains some oxalic acid, limit consumption to a handful per day. Medicinal Summary Leaves, Flowers, Stems - fever reducer; diuretic; relieves indigestion (tisane, tincture) Leaf Arrangement: The leaves of Oxalis species are typically arranged alternately along the stem. Leaves fold up together at night. Leaf Shape: Leaves are compound with three heart-shaped (cordate) leaflets, each leaflet measuring around 1/2 to 1.5 inch in width (depends on species). Leaf Venation: Pinnate venation with veins running from the base to the tip of each leaflet. Leaf Margin: The leaf margin is typically entire, but it can be slightly toothed. Leaf Color: The leaves vary in color but are often medium green. Flower Structure: Five-petaled flowers with distinctive, funnel-shaped petals. Flower Color: Flower colors can vary widely among Oxalis species, including shades of white, yellow, pink, and purple. Fruit: The fruit is an elongated, pointed capsule containing small seeds. Seed: Small, rounded seeds are found within the capsules. Stem: The stem is usually smooth and erect, often with no or few hairs. Hairs: Fine hairs may be present on some species but are not a prominent feature. Height: Oxalis species vary in height but are generally low-growing, typically ranging from a few inches to about a foot. Wood sorrel (Oxalis crassipes) Another picture of wood sorrel (Oxalis crassipes) Close-ups of wood sorrel flower (Oxalis crassipes). Common yard weed wood sorrel (Oxalis dillenii), often mistaken for a clover. My girls love the tangy wood sorrel "bananas" or seed pods of wood sorrel. Purple-flower, giant wood sorrel with their tubers. Two types of wood sorrel. Close-up of wood sorrel tubers. Each "scale" is a thick, triangular wedge that easily break away from each other. Tubers from a decorative, purple-leaf wood sorrel. Wood Sorrel leaves (left) are heart-shaped while Clover leaves (right) are rounded. Texas distribution, attributed to U. S. Department of Agriculture. The marked counties are guidelines only. Plants may appear in other counties, especially if used in landscaping. North American distribution, attributed to U. S. Department of Agriculture. Patches of wood sorrel are very prevalent on forest floors, often near wild violets, cleavers, wild onions, etc... The three-lobed leaf looks similar to clover/shamrocks but sorrels have a cleft at the top, giving them a heart-shape whereas clovers are round or slightly pointed. Wood sorrel leaves range in size from 1/2" to almost 3" across. They have a very strong, tangy flavor that some people find too intense. It only takes a few to spice up a salad. The purplish-pink flowers can also be added to salads though mainly just for color. Wood sorrel whipped into butter makes a lemony-butter that goes great on bread, fish, and crawfish. Throw 1/2 cup of chopped wood sorrel into a can of cream of mushroom soup if you want to tick off Poland (sorry, you'll have tp take my class in person to get that full story!). Wood sorrel tubers can be just about any color of the rainbow. They have less oxalic acid than other parts of the plants so they aren't as tangy. Their flavor is somewhat like a carrot and so that's how I use them: raw, steamed, or tossed into stews. Excessive amounts of oxalic acid theoretically can lead to kidney stones though there's never been any actual reported case of this happening. Cautious types should be sure to drink plenty of water when eating wood sorrel. Also avoid dairy products, if possible, as the oxalic acid binds strongly to the calcium to make calcium oxalate, which is the key mineral of the kidney stones. Buy my book!
