ergot 14
Gallicism designating ergot of rye, blight of rye, claviceps purpurea fungus of rye and other cereals which bears fruit on the spike in the form of small blackish purple Horn, cause the syndrome of the fire of San Antonio in the middle ages, associated with witchcraft. Recent poisonings and known deaths happened in France in the mid-20th century. Everything was caused by eating rye bread mixed with abundant ergot especially the very rainy years. The ergot ergotamine constrains the veins sometimes too.
