Trapped In Time 89 The Daffodils Speak Part 5

Despite the lethal potential of Narcissus alkaloids, they have been used for centuries as traditional medicines for a variety of complaints, including cancer. Plants thought to be N. poeticus and N. tazetta are described in the Bible in the treatment for what is thought to be cancer. In the Cla.s.sical Greek world Hippocrates (ca. B.C. 460–370) recommended a pessary prepared from narcissus oil for uterine tumors, a practice continued by Pedanius Dioscorides (ca. A.D. 40–90) and Sora.n.u.s of Ephesus (A.D. 98–138) in the first and second centuries A.D., while the Roman Pliny the Elder (A.D. 23–79), advocated topical use. The bulbs of N. poeticus contain the antineoplastic agent narciclasine. This usage is also found in later Arabian, North African, Central American and Chinese medicine during the Middle Ages. In China N. tazetta var. chinensis was grown as an ornamental plant but the bulbs were applied topically to tumors in traditional folk medicine. These bulbs contain pretazettine, an active ant.i.tumor compound.

Narcissus products have received a variety of other uses. The Roman physician Aulus Cornelius Celsus listed narcissus root in De Medicina among medical herbs, described as emollient, erodent, and "powerful to disperse whatever has collected in any part of the body". N. tazetta bulbs were used in Turkey as a remedy for abscesses in the belief they were antiphlogistic and a.n.a.lgesic. Other uses include the application to wounds, strains, painful joints and various local ailments as an ointment called 'Narcissimum'. Powdered flowers have also been used medically, as an emetic, a decongestant and for the relief of dysentery, in the form of a syrup or infusion. The French used the flowers as an antispasmodic, the Arabs the oil for baldness and also an aphrodisiac. In the eighteenth century the Irish herbal of John K'Eogh recommended pounding the roots in honey for use on burns, bruises, dislocations and freckles, and for drawing out thorns and splinters. N. tazetta bulbs have also been used for contraception, while the flowers have been recommended for hysteria and epilepsy. A homeopathic medicine made from bulbs was prescribed for bronchitis and whooping cough.

Biological properties

Extracts of Narcissus have demonstrated a number of potentially useful biological properties including antiviral, prophage induction, antibacterial, antifungal, antimalarial, insecticidal, cytotoxic, ant.i.tumor, antimitotic, antiplatelet, hypotensive, emetic, acetylcholine esterase inhibitory, antifertility, antinociceptive, chronotropic, pheromone, plant growth inhibitor, and allelopathic. An ethanol extract of Narcissus bulbs was found effective in one mouse model of nociception, parbenzoquinone induced abdominal constriction, but not in another, the hot plate test. Most of these properties are due to alkaloids, but some are also due to mannosbinding lectins. The most-studied alkaloids in this group are galantamine (galanthamine), lycorine, narciclasine, and pretazettine.

It is likely that the traditional use of narcissi for the treatment of cancer was due to the presence of isocarbostyril const.i.tuents such as narciclasine, pancratistatin and their congeners. N. poeticus contains about 0.12g of narciclasine per kg of fresh bulbs.

Acetylcholine esterase inhibition has attracted the most interest as a possible therapeutic intervention, with activity varying by a thousandfold between species, and the greatest activity seen in those that contain galantamine or epinorgalanthamine.

The rodent repellant properties of Narcissus alkaloids have been utilised in horticulture to protect more vulnerable bulbs.

Therapeutics

Of all the alkaloids, only galantamine has made it to therapeutic use in man, as the drug galantamine for Alzheimer's disease. Galantamine is an acetylcholine esterase inhibitor which crosses the blood brain barrier and is active within the central nervous system. Daffodils are grown commercially near Brecon in Powys, Wales, to produce galantamine.

Commercial uses

Throughout history the scent of narcissi has been an important ingredient of perfumes, a quality that comes from essential oils rather than alkaloids. Narcissi are also an important horticultural crop] and source of cut flowers (floriculture).

Daffodil production in the Netherlands

The Netherlands, which is the most important source of flower bulbs worldwide is also a major centre of narcissus production. Of 16,700 hectares (ha) under cultivation for flower bulbs, narcissi account for about 1,800 hectares. In the 1990s narcissus bulb production was at 260 million, sixth in size after tulips, gladioli, irises, crocuses and lilies and in 2012 it was ranked third. About two-thirds of the area under cultivation is dedicated to about 20 of the most popular varieties. In the 2009/2010 season 470 cultivars were produced on 1578 ha. By far the largest area cultivated is for the miniature "Tête-à-Tête", followed at some distance by "Carlton".

Carlton" and "Ice Follies" (have a long history of cultivation, together with "Dutch Master" and "Golden Harvest" (1: yellow). "Carlton" and "Golden Harvest" were introduced in 1927, and "Ice Follies" in 1953. "Carlton", with over 9000 million bulbs (350 000 tons), is among the more numerous individual plants produced in the world. The other major areas of production are the United States, Israel which exported 25 million N. tazetta cultivar bulbs in 2003, and the United Kingdom.

In the United Kingdom a total of 4100 ha were planted with bulbs, of which 3800 ha were Narcissi, the UK's most important bulb crop, much of which is for export, making this the largest global production centre, about half of the total production area. While some of the production is for forcing, most is for dry bulb production. Bulb production and forcing occurs in the East, while production in the south west is mainly for outdoor flower production.[198] The farm gate value was estimated at £10m in 2007.

N triandrus "Thalia" is the national flower of Wales, a.s.sociated with Saint David's Day (March 1). The narcissus is also a national flower symbolizing the new year or Newroz in the Iranian culture.

In the West, the narcissus is perceived as a symbol of vanity, in the East as a symbol of wealth and good fortune, while in Persian literature, the narcissus is a symbol of beautiful eyes.

Western Culture

In western culture, the daffodil is also a.s.sociated with spring festivals such as Lent and its successor Easter. In Germany, the wild narcissus, N. pseudonarcissus, is known as the Osterglocke or "Easter bell." In the United Kingdom, the daffodil is sometimes referred to as the Lenten lily.

Although prized as an ornamental flower, some people consider narcissi unlucky, because they hang their heads implying misfortune. White narcissi, such as N triandrus "Thalia", are especially a.s.sociated with death and have been called grave flowers. In Ancient Greece, narcissi were planted near tombs, and Robert Herrick describes them as portents of death, an a.s.sociation which also appears in the myth of Persephone and the underworld.
