The grey hairy herb with tiny white flowers coiled like a scorpion's tail, appearing in cornfields and dry ground in late summer. It passes for harmless and is liver-toxic.

How to tell it

The whole plant is covered in flattened white hairs, greyish in appearance. Very small white flowers lined along one side of a coiled branch that unrolls as it opens. Oval, soft, wrinkled leaves.

What it is confused with

Blue hound's tongue

Cynoglossum creticum

Harmless confusion

They are from the same lineage and share the alkaloids and the coiled branch. Heliotrope has tiny white flowers; hound's tongue has blue flowers with dark veins, much larger. Neither is consumed.

What it is for

None. It was applied to warts, hence the name, but what matters today is the other side: it contains pyrrolizidine alkaloids and causes cumulative liver damage. It is a real problem in cereals and fodder, because it contaminates harvested grain.
