Snow drops

Actually, they are milk flowers, from the Greek, Gala = milk and Anthos = flower, Galanthus.

In 1753, Linnaeus, created the genus based on Galanthus nivalis, milk flower of the snow.

It was suggested by Andreas Plaitakis and Roger Duvoisin in 1983 that the mysterious magical herb moly that appears in Homer's Odyssey is actually snowdrop. An active substance in snowdrop is called galantamine, which, as Acetylcholinesterase inhibitor, could have acted as an antidote to Circe's poisons. Galantamine (or galanthamine) can be helpful in the treatment of Alzheimer's disease, though it is not a cure; the substance also occurs naturally indaffodils and other narcissi.
Snowdrops contain also an active lectin or agglutinin named GNA for Galanthus nivalis agglutinin.
