Also referred to as spinach dock, sorrel is a plant known for its tart taste and powerful health benefits.
This vibrant leafy green and its fruit are used to add a sharp, citrusy flavor to soups, sauces, salads, and beverages. Certain varieties are also used to make herbal teas, tinctures, and supplements.
This article explores some of the benefits, downsides, and uses of sorrel.
Sorrel is a type of leafy green used as an herb and a vegetable.
It’s cultivated in Europe, Central Asia, and certain parts of North America, Australia, and New Zealand (1).
It has a sour, lemon-like flavor and is often featured in dishes like soups, stews, and curries. It’s also used medicinally, as it’s touted to promote healthy digestion, decrease inflammation, and treat mouth ulcers.
The two most commonly grown types are known as French and common sorrel. Compared with common sorrel, the French version is less bitter and grows taller with smaller, more rounded leaves.
Other species of sorrel include:
- sheep sorrel
- arctic dock
- patience dock
- broad-leaved sorrel
- red-veined sorrel
Certain plants and foods share a similar name but are unrelated. For example, wood sorrel is a type of edible weed found throughout North America. Similarly, in Jamaica, the term sorrel refers to roselle, a type of hibiscus plant.

Sorrel has been linked to several powerful health benefits.
Rich in antioxidants
Sorrel is a great source of antioxidants, which are beneficial compounds that protect your cells from damage by neutralizing harmful free radicals.
Antioxidants may help prevent many chronic conditions, including heart disease, cancer, and type 2 diabetes (
In particular, studies show that sorrel is rich in the following antioxidants (
- phenolic acids
One test-tube study compared the antioxidant properties of 10 plant extracts and found that red sorrel exhibited the highest antioxidant activity (
Another test-tube study showed that Rumex hastatus, a specific species of sorrel, scavenged harmful free radicals. This indicates that it might be useful in the treatment of neurodegenerative disorders like Alzheimer’s disease (
May decrease cancer cell growth
Although research in humans is lacking, some test-tube and animal studies have found that sorrel may block the growth and spread of certain types of cancer cells.
For instance, a test-tube study showed that several species of sorrel killed breast, cervical, and skin cancer cells (
Furthermore, in one study in rats with leukemia, a mixture containing sorrel extract and other ingredients like greater burdock, slippery elm, and Chinese rhubarb prevented weight loss and improved white blood cell levels (11).
Still, more studies are needed to determine how sorrel may affect cancer growth in humans when consumed as part of a balanced diet.
Supports heart health
Animal research suggests that sorrel may improve several aspects of heart health.
In one study in rats, sorrel extract was shown to modify certain pathways involved in platelet aggregation — the process in which platelets in your blood clump together — to decrease blood clot formation (
Nevertheless, human studies on sorrel and heart health are lacking. More research is needed to explore this green’s effect on human heart health.
Sorrel is rich in antioxidants. It may support heart health and hinder cancer cell growth.
Most healthy adults can enjoy sorrel in moderation as part of a healthy, well-rounded diet.
Yet, some people may be allergic to sorrel. If you experience any adverse symptoms after eating it or are allergic to other plants in the same family, such as rhubarb, buckwheat, and knotweed, you may need to avoid it.
Calcium and oxalate can also bind together. This may contribute to the formation of calcium oxalate kidney stones, which are hard mineral deposits in the kidneys that can cause symptoms like pain, nausea, and vomiting (
However, rather than eliminating oxalate-rich foods like sorrel from your diet, try to increase your intake of calcium, limit your salt consumption, and drink plenty of water to help prevent calcium oxalate kidney stones (
Some people may be allergic to sorrel. It also contains oxalate, which can impair calcium absorption and contribute to the formation of kidney stones.
Sorrel is available both fresh and dried at many specialty stores and online retailers.
Sorrel can also be purchased in tincture or capsule form, with most supplements offering doses of 400–800 mg.
Although these products are claimed to enhance detoxification, boost immune function, and reduce inflammation, there’s no research available on their efficacy, safety, or side effects.
If you have any underlying health conditions or take medications, it’s best to talk with your doctor before using any herbal supplements.
Sorrel is available fresh and dried and can be found in certain supplements. It may also be used in herbal tea blends like Essiac tea.
Sorrel has a tart, lemony flavor that works well in a variety of recipes.

Sorrel sauce is another popular recipe that uses these greens. It’s usually served alongside seafood dishes like salmon.
Most recipes combine the tart taste of sorrel with ingredients like chives, heavy cream, butter, and chervil — a type of herb that’s related to parsley.
