Wood sorrel, a common plant, is recognized by its heart-shaped, clover-like leaves and tangy taste. This herbaceous perennial, belonging to the Oxalis genus, often features delicate flowers ranging from white to yellow or violet purple. Historically, it has been utilized for its unique flavor and health-supporting properties. Its tart profile makes it useful in culinary and traditional applications.
Nutritional Content
Wood sorrel contains beneficial compounds, including Vitamin C, beta-carotene (converted to Vitamin A), and various flavonoids. These, along with other phenolic compounds, act as antioxidants. It also contains minerals like magnesium, manganese, copper, iron, and potassium, plus dietary fiber. Its sour taste comes from oxalic acid.
Health Advantages
Wood sorrel’s Vitamin C content supports the immune system, and its antioxidants, including flavonoids and phenolic compounds, help protect cells from free radical damage. Traditionally, it has been used for digestive discomforts like nausea and stomach upset, and for anti-inflammatory purposes. Historically, its Vitamin C content helped prevent scurvy. It has also been used for liver health, as a diuretic, and for healing minor wounds and soothing mouth sores.
Culinary and Traditional Uses
Wood sorrel’s leaves, flowers, and stems are edible, offering a tart flavor often compared to lemon or green apple. This distinct taste makes it versatile in culinary preparations, added raw to salads as a garnish, or used in cooked dishes like soups, casseroles, or sauces for fish. Beyond food, it has been used to create refreshing beverages, including teas or “dry lemonade.” Native American traditions used it by chewing leaves to alleviate nausea, mouth sores, and sore throats, and it was also brewed into teas for fevers and urinary infections.
Important Safety Information
While wood sorrel offers culinary appeal and benefits, it contains oxalic acid, requiring cautious consumption. This compound can bind with calcium, potentially affecting nutrient absorption and contributing to kidney stone formation. Moderation is crucial, especially for those with existing health conditions like kidney issues, kidney stones, gout, or rheumatism, who should exercise caution or avoid significant quantities. Consuming large amounts is unsafe and can lead to adverse effects, including digestive irritation, nausea, or kidney damage. Proper identification is also essential to prevent accidental ingestion of toxic look-alike plants.
