Overview

Overview Information

Sorrel is a plant. People use the above ground parts for medicine.

People take sorrel in combination with other ingredients for swelling (inflammation) of the nasal cavity and sinuses (rhinosinusitis), and for swelling (inflammation) of the main airways in the lung (bronchitis). But there is no good scientific evidence to support these uses.

Sorrel is also used as an ingredient in sauces and soups.

How does it work?

Sorrel contains tannins, which have a drying effect to reduce mucous production.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Breast cancer.
  • Fluid retention.
  • Swelling (inflammation) of the main airways in the lung (bronchitis).
  • Swelling (inflammation) of the nasal cavity and sinuses (rhinosinusitis).
  • Other conditions.
More evidence is needed to rate the effectiveness of sorrel for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Sorrel is POSSIBLY SAFE for most people when consumed in food amounts. It is also POSSIBLY SAFE to take sorrel in medicinal amounts as part of certain combination products. These include a specific product that contains gentian root, European elder flower, verbena, and cowslip flower (Sinupret, SinuComp), as well as a specific product that contains burdock root, Indian rhubarb, and slippery elm bark (Essiac). These combinations can cause upset stomach. In larger doses, sorrel can cause damage to the kidneys, liver, and digestive organs.

Sorrel is POSSIBLY UNSAFE when taken in large amounts, since it might increase the risk of developing kidney stones.

Special Precautions & Warnings:

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 isn't enough reliable information to know if sorrel is safe to use when breast-feeding. Stay on the safe side and avoid use.

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.

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 or are at risk of getting kidney stones.

Surgery: Sorrel can slow blood clotting. There is concern that it might cause extra bleeding during and after surgery. Stop using sorrel at least 2 weeks before a scheduled surgery.

The following doses have been studied in scientific research:

BY MOUTH:

  • Swelling (inflammation) of the nasal cavity and sinuses (rhinosinusitis): A specific combination product containing 36 mg of sorrel, 12 mg of gentian root, and 36 mg each of European elder flower, verbena, and cowslip flower has been taken three times daily for up to 14 days.
