Couch Grass (Elymus repens)

Saw Palmetto (Serenoa repens)

About

Couch grass is a vigorous perennial growing to 32 inches with a long, creeping rhizome, slender leaves, and erect spikes bearing green flowers aligned in two rows. Found in Europe, the Americas, northern Asia, and Australia, it is an invasive weed harvested throughout the year. In classical times, both Dioscorides (40-90 CE) and Pliny (23-79 CE) recommended couch grass root for poor urine flow and kidney stones. The herbalist John Gerard wrote in 1597 that 'Couch-grasse be an unwelcome guest to fields and gardens, yet his physicke virtues do recompense those hurts; for it openeth the stoppings of the liver and reins [ureters] without heat.' In times of famine, the root was roasted and ground as a substitute for coffee and flour.

Saw palmetto (Serenoa repens), also known as Sabal serrulata, is a small, slow-growing palm (to about 20 ft / 6 m) bearing fan-like fronds and white flowers that develop into dark purple to black berries. Historically used by Native Americans as a tonic, saw palmetto has become renowned for supporting prostate health and urinary function.
