Long before it was ever pressed into a modern tincture, sawbrier's tangled roots were dug by Native American communities and rural Appalachian and Southern households alike, valued as a starchy food source and a spring tonic root. The rhizomes were pounded, soaked, and strained to release a reddish starch that was dried into a meal or simmered into a jelly, a practical food in lean seasons. Herbalists of the region also steeped the root as a traditional blood purifying tonic and used washes made from it on troubled skin, much as other native Smilax species were used across the South. The tender young shoots, harvested in spring while still soft, were traditionally cooked and eaten much like asparagus.
Safety.
Sawbrier is not known to be toxic, but its sharp recurved thorns can scratch skin while foraging, so wear gloves. Confirm identification carefully, since it resembles other Smilax species and thorny vines.
