Sheep Sorrel


Some wild plants seem to intrigue kids. Sheep sorrel (Rumex acetosella) is one of them. Its leaves have an arrowhead shape and their flavor is sour like a combination of lemon and sour apple. Yes, they are edible, so these weeds pose no real danger. I like the flavor too, but I rarely consume much of it.

This plant is a good indicator of infertile acid soil. It grows in dry open places where most other plants don’t. It also tolerates wetness and even alkaline salty soils, but under those conditions many other weeds dominate it. If your lawn contains much sheep sorrel there’s a good chance you haven’t applied fertilizer or lime recently.

Sheep sorrel is a perennial and very cold tolerant. It is hardy throughout the lower forty-eight and young plants tolerate substantial frost. Most leaves remain close to the ground, but reddish brown flower stalks can be almost two feet tall. Plants are dioecious (individual flowers are either male or female, and entire plants are the same sex) and are pollinated by wind. Seeds mature in early to midsummer.

Many wild animals love it, and eat both leaves and seed heads. Unlike most plants, this herb does not get tough or bitter as it matures. Its flavor and texture remain constant.

This buckwheat relative has been used medicinally for centuries.  In Europe as well as America is has been included as a holistic treatment for various cancers. It’s a rich source of potassium, iron, manganese, phosphorous, beta-carotene, and vitamin C. The combination of these vitamins and minerals promotes the glandular health of the entire body. Sheep Sorrel also contains carotenoids, as well as citric, malic, tannic and tartaric acids.

Does it have a downside? In small doses it probably doesn’t. I don’t mind using a little bit to spice up a salad, but I don’t consume large quantities of it as a fresh herb. The reason is its high concentration of oxalic acid.

Oxalates are bad news to people who form kidney stones or suffer from gout. I don’t, but my wife is a stone former. Oxalic acid is water soluble, so boiling the greens would greatly reduce its concentration. Sheep sorrel makes an acceptable cooked green seasoned with a little salt and butter.

Kidney stones and gout are not the only maladies linked to high levels of oxalates. I have arthritis in my hands and feet. Sometimes it can be pretty bad, and oxalic acid aggravates this condition substantially. Many foods I like are high in this compound and its chemical cousins.

What oxalic acid does is interfere with calcium absorption, causing bone and joint problems. It reacts with calcium and other metallic elements like magnesium, potassium, and sodium. Oxalate salts are formed and these materials are bound up and can’t be easily absorbed by the body.

Don’t get paranoid though. Unless your mineral nutrition is very poor you would have to ingest oxalates in mega doses to pose major problems. Eat a variety of foods and enjoy life. Our Lord has given us countless blessings to eat. We’ve also been blessed with a brain and it is our obligation to use to its fullest.

About tedmanzer

I grew up in Old Town Maine and got a B.S. at the University of Maine in Plant Sciences/ minor in Botany. From there I moved to West Virginia and earned a M.S. in Agronomy at WVU. I also met my wife there. She grew up in rural WV as the daughter of tenant farmers who raised cattle and hogs. Their lifestyle at times was one of subsistence and I learned a lot from them. I've always been a foraging buff, but combining my formal botanical knowledge with their practical 'Foxfire-type' background opened up my eyes a little more. I now teach agriculture to high school students at Northeastern High School in Elizabeth City, NC. My wife teaches with me and we make a great team. I also write a weekly nature/foraging column for the local paper (dailyadvance.com) and frequently publish articles in several other newspapers in northeastern North Carolina. I also have written several Christian nature/adventure novels that I plan to publish eventually. One is a five book family saga I call the 'Forgotten Virtues' series. In the first book, Never Alone, a young boy comes of age after his father dies in a plane crash, and he has to make it alone. Never Alone is now available in paperback, Kindle and Nook. The second book, Strange Courage, takes Carl from his High School graduation to his recovery from a nasty divorce. The third book, Second Chances, takes Carl from his ex-wife's death and the custody of his son to his heroic death at age 59. The fourth book, Promises Kept, depicts how his grandchildren react and adjust to his death. In the final book, Grandfather's Way, his youngest and most timid granddaughter emerges from the shadow of her overachieving family and accomplishes more in four months than most do in a lifetime. I use many foraging references with a lot of the plants I profile in these articles in those books.

    from reading this, it seems as though this plant is good only for those who don’t produce stones, but how do you know if you do or not? so you don’t eat this plant then find out you do make stones.

  2. this plant looks cool and has many uses but it also has some drawbacks

  3. It’s interesting that this plant can grow in dry places
