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". 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".
Caladenia nivalis Caladenia nivalis Caladenia nivalis, commonly known as the exotic spider orchid or crystalline spider orchid, is a species of orchid endemic to the south-west of Western Australia. This orchid is easily distinguished by its bright white to pale pink and red flowers and its narrow range in and near the Leeuwin-Naturaliste National Park. "Caladenia nivalis" is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, long and wide. Up to three bright white, sometimes pale pink flowers long and wide are borne on a stalk tall. The sepals have thick, brown, club-like glandular tips.
