How does Sorrel work?

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

Are there safety concerns?

Sorrel is POSSIBLY SAFE for most people when consumed in food amounts or when taken by mouth in medicinal amounts as part of a combination product containing gentian root, European elder flower, verbena, and cowslip flower (SinuComp, Sinupret). The combination product can cause digestive system upset and occasionally allergic skin rash.

Sorrel is POSSIBLY UNSAFE when taken by mouth in large amounts, since it might increase the risk of developing kidney stones. There is also a report of death after consuming a large amount (500 grams) of sorrel.

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.

Dosing considerations for Sorrel.

The following doses have been studied in scientific research:

BY MOUTH:
  • For sinus infections: A specific combination product containing 36 mg of sorrel, plus 12 mg of gentian root, and 36 mg each of European elder flower, verbena, and cowslip flower three times daily.
