Snowdrop
General poisoning notes:
Snowdrop (Galanthus
nivalis) is an outdoor ornamental spring flower. This plant contains the
alkaloid lycorine, which can cause poisoning. Some individuals were poisoned
after ingesting the bulbs as emergency food in Holland during World War II.
Large amounts of bulbs need to be ingested to produce toxic reactions (Lampe
and McCann 1985, Fuller and McClintock 1986).

Active substances
Snowdrops
contain an active substance called galantamine, (or galanthamine), which 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. Potatoes have been genetically modified with the GNA gene. In 1998
Árpád Pusztai said in an interview on a World in Action programme that his
group had observed damage to the intestines and immune systems of rats fed the
genetically modified potatoes. 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". These remarks started the so-called
Pusztai affair.
