About

Polygonatum biflorum (smooth Solomon's-seal, great Solomon's-seal, Solomon's seal) is an herbaceous flowering plant native to eastern and central North America. The plant is said to possess scars on the rhizome that resemble the ancient Hebrew seal of King Solomon. It is often confused with Maianthemum racemosum (called "Solomon's plume" or "false Solomon's seal"), which has upright flowers.

Uses

Historically, the Native Americans consumed the starch-rich rhizomes of smooth Solomon's-seal as a "potato-like food" used to make breads and soups. The young shoots are also edible, raw or boiled for an asparagus-like food. Smooth Solomon's-seal was also used in herbal medicine. For example, the rhizome was used in making a tonic for gout and rheumatism. Smooth Solomon's-seal has had nearly a dozen uses in herbal medicine including as an anti-inflammatory, sedative, and tonic. Smooth Solomon's-seal is not used in large-scale agriculture.
