Yellow Dock has narrow, pointed leaves with dense whorls of flowers. The roots of yellow dock are harvested in Spring and Fall. The roots stimulate liver bile, clear toxins, and are used for chronic skin disorders. They treat psoriasis and constipation. The iron rich leaves soothe nettle stings.
All bitter tastes help detoxify the body.
Sweet and sour tastes together helps to balance the liver. Yellow Dock strangely enough is a challenge to get started from seed. For a plant that can become a troublesome weed this does seem strange. Best to sprinkle seed on a patch of disturbed ground. Germination can occur within 2 weeks but may also take up to 3 years.
