A
Eurasian climbing shrub seen growing along road sides. Hops
are perennials belonging to the group of nettles. The female
plants bear cone-shaped formations, representing clusters
of blossoms. It is this cone that is processed for use in
beer. Hops impart a bitter flavor and pleasant aroma to beer,
increasing the refreshing quality and stimulating digestion.
They help to clarify the wort and assist in preserving beer.

Hops
are a common plant in Europe, cultivated in regions where beer
is produced, since they are at the basis of the bitter flavouring
of this drink. In spite of the fact that this plant has not
been much used in ancient times for its therapeutic virtues,
it has been mentioned since the 12th century as a "remedy
against melancholy" for its aperitive (stimulating the
appetite), depurative, laxative and vermifuge (serving to destroy
or expel parasitic worms) properties, while there has been a
confirmation of some effects traditionally attributed to it,
such as particularly the sedative and relaxing action.

These functions are widely justified considering the content
in aminoacids and in hormone-like substances, while, because
of the content of the essential oil and of phyto-hormonal
substances, hops is also effective for the healthy growth
of hair, since it stimulates metabolic functions of the superficial
tissues of the scalp.The main components of hops are a resin
and a volatile oil. Besides, hops contain flavonoids, proteins,
starch, glucids, and phytoestrogens. |

Hops
are most commonly used for their calming effect on the nervous
system. Hops is an excellent sedative - used to induce better
sleeping patterns - and in cough syrups. Dried flowers may be
sewn into a pillow to help insomnia and healing. Hops tea is
also recommended for insomnia, nervous diarrhea, and restlessness.
Hops poultice is used for abscesses - boils - tumors and pain.
Honey combined with hops is excellent for bronchitis.

Il
Luppolo è universalmente conosciuto come aromatizzante
e conservante naturale nella birra. Tradizionalemtne i fiori
di Luppolo sono stati usati come aiuto per dormire bene. Cuscini
riempiti di Luppolo venivano usati come guanciale. Il Luppolo
è stato usato per la prima volta nel XVI secolo in inghilterra
per aromatizzare la birra.Il Luppolo viene ancora usato in Europa
come rimedio per l'insonnia. |

CORVALLIS,
Ore. (AP) -- Compounds found in the plant called hops, used
to flavor and preserve beer, may help protect against cancer,
researchers say. Studies indicated the compounds, called flavonoids,
helped inhibit an enzyme called cytochrome P450 that can activate
the cancer process |

State University scientists also found that some of the flavonoids
helped enhance the impact of a class of enzymes, called quinone
reductase, that can block cancer-causing substances that already
have been activated. "We treated human breast, colon and
ovarian cells that were cancerous with concentrations (of flavonoids)
that were not harmful to normal cells and found that some of
the hops flavonoids were toxic to cancer cells,'' said Donald
Buhler, an agricultural chemist and lead researcher.The substance
in the hops flavonoids most toxic to cancer cells is named xanthohumol,
he said. Buhler warned the research should not be used to endorse
more beer consumption. "I wouldn't encourage people to
drink more,'' he said. "Obviously there's a downside to
drinking. But these results are really interesting. If these
things really prove to be beneficial it might be possible to
find a way to get them to people in capsules or some other concentrated
form.'' His findings recently were reported in Seattle at the
annual meeting of the international Society of Toxicology.

By
Willam Loob. An apple a day, according to folk wisdom, can keep
the physician from knocking on your door. Now, according to
a team of cancer researchers in Japan, a pint of beer with the
grilled steak might not be such a bad idea either. The results
of a study conducted by investigators at Okayama University
offers some evidence that beer might actually help counteract
the carcinogenic effects of a class of compounds found in cooked
food. Specifically the study looked at the effects of beer on
the mutations caused by these compounds that are the first steps
in changing healthy cells into cancerous ones. The results were
published in the January 1999 issue of the Journal of Agricultural
and Food Chemistry.The researchers examined the effectiveness
of 24 different beers in thwarting mutations associated with
several types of heterocyclic amines produced when heat is applied
to food. Foods containing proteins produce especially high levels
of the compounds, and their connection to tumor-forming processes
were first reported more than a decade ago. |

The
beers tested came from around the world, and included 17 lagers,
four stouts, two ales and one nonalcoholic brew. Interestingly,
the researchers found that the stouts demonstrated the most
dramatic effects in inhibiting the cancer-related mutations,
while the nonalcoholic beer and one of the lagers showed no
such effects. The findings in this study help reinforce the
idea that hops may have anticancer properties, as reported by
others. |

In a 1995 study, conducted by another group Japanese researchers,
experiments demonstrated that the flavonoids in hops (the yellow
pigments in the blossoms) inhibit an inflammatory reaction in
human skin tumor cells. Another study by investigators at Oregon
State University in 1998 also showed that the flavonoids were
toxic to certain cancerous human cells, though they were tolerated
well by normal, noncancerous cells from the same types of human
tissues. |
