Sour Dock, also known as Sorrel, is commonly found in Europe. Sorrel (Rumex acetosa) is a member of the Polygonaceae family. The leaves and whole herb can be used medicinally. Sorrel contains tannins (7-15%), oxalates, anthracene derivatives (anthranoids, aglycones, physcion, chryosphanol, emodin, rhein, aloe-emodin, aloe-emodin acetate, and their glucosides) and flavonoids. Sorrel is as a diuretic as well as for acute and chronic inflammation of the nasal passage and respiratory tract. It also has the ability to stimulate secretion and improve resistance to infections (antibacterial). It is often used in combination with other herbs like elder flower, verbena, cowslip flower, and gentian root for maintaining healthy sinuses.
Tannins, in doses over 10% may cause gastrointestinal disturbances.
