ADDITIONAL FACTS UNIQUE TO THE SPECIES (IF ANY)

The common name of Sneezeweed is based on the historic use of crushed dried leaves and heads to make a form of snuff that causes sneezing. The leaves, flowers, and seeds are poisonous to humans if eaten in large quantities, causing gastric and intestinal irritation, which can become fatal.  The chemicals in the plant can poison livestock, particularly sheep and cattle.
