Christmas Holidays are behind us, but why not
extend a little bit of this wonderful feast atmosphere by presenting our new
content highlight - holly? Did you know that tradition states that a sprig of
holly placed inside the entry-way doorframe guards the home against lightning
strikes? Or that holly was also revered by Celts, Romans and Germans as a
symbol of eternal life?

Christmas
holly is one of the symbols of Christmas. Christian folklore states that holly
thorns represent Christ's crown of thorns, and the red berries his blood. Holly
captures our attention with its prickly, waxy leaves and later, its bright red
berries. Its home is western, central and southern Europe, northern Africa,
Asia Minor and northern Iran. It is often planted as a decorative shrub in
parks. From May through June it blooms with tiny white flowers. In the fall,
these give rise to small red berries. The plant contains the alkaloid
theobromine, as well as other substances like saponins and terpenoids.

Cases of
poisoning occur mainly in children, from consuming the bright red berries.
Symptoms are nausea, strong diarrhea and sleepiness. Initial symptoms can occur
in children with the consumption of as few as two berries. A fatal dose for an
adult is considered to be 20-30 berries. However, newer research suggests that
even larger doses cause only vomiting and diarrhea.
