Rattlesnake Master
Eryngium yuccifolium
Rattlesnake master earned its startling name from an old folk belief, held by settlers and passed down through Southeastern tribal traditions, that a preparation of the root could counteract the venom of a rattlesnake bite. Its more documented traditional role was different: several Native peoples of the tallgrass prairie and Southeast, prepared the root as a powerful emetic used in purification ceremonies, and it appeared in folk remedies for coughs and other respiratory complaints. Long before it was studied by botanists, its tough, spiky, parallel-veined leaves, so unlike anything else in the carrot family, were noticed and split by Native artisans to weave sandals and cordage, much as true yucca leaves were used elsewhere. Today it survives mostly as a beloved anchor of prairie restoration gardens rather than as a working medicine cabinet herb.

The tradition we can stand behind has no household remedy for this plant, so we list none. If that changes as the library grows, this page will grow with it.
Safety.
The root was traditionally used as a strong emetic to deliberately induce vomiting, and careless use can cause significant nausea and digestive upset. Despite the name, it has no evidence of treating snakebite, which is always a medical emergency.
