Red Sorrel has beautiful, deep red-veined leaves 3-6 inches long and lovely, star-shaped flowers. Similar to common wood sorrel, Red Sorrel leaves have a tart, lemony tang derived from oxalic acid. Just one cup of Red Sorrel provides 2.6g of protein, which is relatively high for an herb, plus over 100% of your daily vitamin A and C needs. Vitamin A is essential for vision and healthy organ function, while vitamin C is an important component for immune health and wound healing. Red Sorrel is also a good source of potassium, which contributes to cardiovascular health by lowering blood pressure.
