this little white drab daisy like flower is sneezewort. It is odd how something quite common like this can pass one by. Apparently the smell of it can make a man (and presumably a woman) sneeze. It was widely used to treat toothache, and blocked noses. Its leaves have a biting hot taste and have been used in salads. Found in Ged's fields at Bridestowe yesterday during a very pleasant walk, and lunch at the excellent White Hart Inn (see link) who have an enormous Great Dane puppy which put the fear of dogs into Spot.
