Galanthus nivalis can be helpful in the treatment of Alzheimer's disease, though it is not a cure. Snowdrops contain also an active lectin or agglutinin named GNA for "Galanthus nivalis agglutinin".

He also said "If I had the choice I would certainly not eat it", and that "I find it's very unfair to use our fellow citizens as guinea pigs".
