If you’ve never come across sorrel, you’re not alone. Unlike more common leafy greens such as spinach or kale, sorrel remains relatively obscure in many parts of the world. However, this humble herb, with its sharp, tangy flavor, has been a staple in European kitchens for centuries. During the Middle Ages, before the introduction of citrus fruits in Europe, sorrel was a prized culinary ingredient, valued for the bright, sour note it added to dishes. Though it eventually fell out of favor, replaced by the lemon, sorrel has been making a quiet but significant comeback in recent years.
Today, sorrel is more than just a flavorful addition to salads, soups, and sauces. It’s also a key ingredient in natural remedies, including the famed Essiac tea, a tonic with purported anti-cancer properties. This lesser-known leafy green, which belongs to the nightshade family, is also used as a natural treatment for infections and inflammation of the sinuses and respiratory tract. So, what exactly is sorrel, and why should you consider adding it to your diet? Let’s dive into the world of sorrel and discover its impressive benefits.
What Is Sorrel?
Sorrel is a perennial herb that belongs to the Polygonaceae family, the same family as buckwheat and rhubarb. It’s often grown as a garden herb or leafy vegetable, but some varieties can also be found growing wild. The plant is known for its bright, tart flavor, which brings a unique and healthy punch to any dish. In addition to its culinary uses, sorrel is available in supplement and tincture form for treating a variety of health conditions.
There are several varieties of sorrel, each with its distinct flavor profile:
- Broad-Leaf Sorrel (Rumex acetosa): This is the most common variety found in markets and nurseries. It has large, arrow-shaped leaves and a sharp, tangy flavor. As a deep-rooted perennial, it can thrive for years in a favorable spot.
- French Sorrel (Rumex scutatus): Also known as buckler-leaf sorrel, this variety has a milder flavor compared to the common sorrel and features smaller, rounder leaves.
- Sheep’s Sorrel (Rumex acetosella): This variety, often called red sorrel, is as sour as the common sorrel but with much smaller leaves. It’s typically foraged in the wild rather than cultivated.
- Red-Veined Sorrel (Rumex sanguineus): Recognizable by the deep red veins running through its leaves, this variety is known for being the least tart of all.
It’s important to note that sorrel should not be confused with Jamaican sorrel or hibiscus, which are used to make a popular holiday drink. Similarly, wood sorrel is a different plant altogether, despite the similar name.

Health Benefits of Sorrel
- Reduces Mucus Production: Sorrel has a natural drying effect on the body, making it an effective remedy for reducing mucus. This is due to its high tannin content, a type of polyphenolic compound found in many plants, including tea. If you’re dealing with a cold or any condition that causes excessive mucus, sorrel can help alleviate the symptoms and speed up recovery.
- Potential Anti-Cancer Properties: Sorrel is rich in vitamins A and C, both of which are vital for a healthy immune system. These properties make it a potential ally in the fight against cancer. Sheep’s sorrel, in particular, is one of the key ingredients in Essiac tea, a herbal remedy that has been used for over a century in cancer treatment. It’s believed to be the “main cancer-killing herb” in the formula, though more research is needed to fully understand its efficacy.
- Relieves Sinus Infections: Sorrel is commonly used to reduce inflammation and pain associated with sinusitis, thanks to its high antioxidant content, particularly vitamin C. These properties help reduce swelling and provide relief from the discomfort caused by sinus infections.
- Soothes Canker Sores: Fresh sorrel leaves can be used as a natural remedy for canker sores. Simply place a fresh leaf against the sore for about a minute, and repeat as necessary. This quick and easy treatment provides relief from the pain and irritation of canker sores.
- Helps Regulate Blood Pressure: Sorrel’s significant potassium content makes it beneficial for cardiovascular health. Potassium is a key mineral that helps maintain fluid balance in the body and acts as a vasodilator, relaxing the blood vessels and reducing blood pressure. This, in turn, decreases the risk of heart-related complications like blood clots and heart disease.
Sorrel vs. Red Clover: Understanding the Differences
While sorrel and red clover share some similarities, they are distinct herbs with different uses and benefits.
- Sheep Sorrel:
- Known for its potential anti-cancer properties.
- Helps treat urinary tract infections, fever, and inflammation.
- Contains tannins that help reduce mucus production.
- Red Clover:
- Helps prevent cancer and lowers cholesterol.
- Contains isoflavones, which convert to phytoestrogens in the body, mimicking the effects of estrogen.

How to Use Sorrel
Sorrel is versatile in the kitchen, with many culinary and medicinal uses. You can make your own Essiac tea with sheep sorrel or use it as a flavorful substitute in recipes that call for other leafy greens. It pairs well with ingredients like peas and leeks and can be used to create a soothing soup.
Sorrel can be challenging to find in regular supermarkets, but it’s often available at farmers’ markets and specialty stores, especially in the spring and summer. As the growing season progresses, the leaves become more bitter, so it’s best to use them when they’re fresh.
When cooking with sorrel, consider the size of the leaves. Smaller leaves are tender and ideal for raw dishes, while larger leaves hold up better when cooked. Sorrel can also be used alongside other greens like kale or spinach to add a lemony accent to your meals.
To store sorrel, you can keep it loosely wrapped in plastic in the fridge if you plan to use it within a couple of days. For longer storage, rinse the leaves, dry them thoroughly, and wrap them in paper towels before placing them in plastic wrap.
Sorrel is also available in supplement form, including tinctures, capsules, and teas. When purchasing sorrel supplements, be sure to follow the recommended dosage and consult with a healthcare professional if you have any concerns.
Potential Risks and Side Effects
While sorrel offers many health benefits, it’s important to consume it in moderation. Sorrel contains oxalic acid, a compound found in many fruits and vegetables, which can be toxic in large doses. Excessive consumption of oxalic acid can lead to the formation of kidney stones. If you have a history of kidney stones or other kidney issues, consult your doctor before adding sorrel to your diet.
It’s also advised to limit sorrel intake in children, pregnant women, and nursing mothers. There is a documented case of death after consuming a large amount of sorrel (specifically 500 grams), but this would require eating an excessive amount. As with any supplement, start with a lower dose and consult a healthcare professional if you’re unsure.
Final Thoughts
Sorrel may not be as well-known as other leafy greens, but it’s a nutrient-dense herb with a wide range of health benefits. Whether you’re looking to boost your immune system, reduce mucus production, or simply add a unique flavor to your dishes, sorrel is worth exploring. Just be mindful of its oxalic acid content, and enjoy this tangy green in moderation.
As sorrel continues to gain recognition for its health benefits and culinary versatility, it’s time to give this hidden gem a place in your kitchen and diet.
