Sternutatory Achillée

achillée sternutatory the ( Achillea ptarmica L.) or “achillée of the marshes” is a hardy perennial belonging to the family of the Astéracées (or Made up) and to the kind Achillea , whose most widespread representative is the Achillée cream slice ( Achillea millefolium ). It is also called button of money or grass to sneeze , or achillée ptarmic .

Difficult to say if this plant really makes sneeze as its name indicates it, the divergent opinion on this point: undoubtedly it causes Allergie S at some, whereas others are completely insensitive there. It is a rather common plant in all Western Europe, except for the Mediterranean regions.
