Sorrel is used for reducing sudden and ongoing pain and swelling (inflammation) of the nasal passages and respiratory tract, for treating bacterial infections along with conventional medicines, and for increasing urine flow (as a diuretic). Sorrel is also an ingredient in the herbal cancer treatment Essiac.
In combination with gentian root, European elder flower, verbena, and cowslip flower, sorrel is used orally for maintaining healthy sinuses and treating sinusitis.
Possibly Effective for...
- Inflamed nasal passage (sinusitis). Some research suggests that taking a specific product that contains sorrel, gentian root, European elderflower, verbena, and cowslip flower (SinuComp; Sinupret, Bionorica Arzneimittel GmbH, Neumarkt, Germany) by mouth for up to 14 days improves symptoms of sinusitis, such as congestion and headache.
Insufficient Evidence to Rate Effectiveness for...
- Breast cancer. Early research suggests that taking a specific product containing sorrel, burdock root, Indian rhubarb, and slippery elm bark (Essiac, Resperin Canada Limited, Waterloo, Ontario, Canada) by mouth does not improve quality of life or mood in people with breast cancer.
- Bronchitis. Early research shows that taking a specific combination product containing sorrel, gentian root, European elderflower, verbena, and cowslip flower (Sinupret, Bionorica Arzneimittel GmbH, Neumarkt, Germany) by mouth for 10 days improves cough and other symptoms of bronchitis.
- Fluid retention.
- Other conditions.

Special Precautions & Warnings:Children: Sorrel is POSSIBLY UNSAFE in children when taken by mouth in large amounts. Sorrel contains oxalic acid. There is concern because a four-year-old child died after eating rhubarb leaves, which also contain oxalic acid.
Pregnancy and breast-feeding: Sorrel is POSSIBLY UNSAFE when taken by mouth in large amounts during pregnancy. Although unlikely, taking sorrel as part of a combination product (Sinupret) during pregnancy might increase the risk of birth defects. There is not enough reliable information about the safety of taking sorrel in medicinal amounts if you are breast-feeding. Stay on the safe side and avoid use.
Kidney disease: Large amounts of sorrel might increase the risk of kidney stones. Don't use sorrel without a healthcare professional's advice if you have ever had kidney stones.
