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.

Famous quotes containing the word active:
“He crafted his writing and loved listening to those tiny explosions when the active brutality of verbs in revolution raced into sweet established nouns to send marching across the page a newly commissioned army of words-on-maneuvers, all decorated in loops, frets, and arrowlike flourishes.”
—Alexander Theroux (b. 1940)
