Liquorice

Liquorice is a confectionery flavoured with the extract of the roots of the liquorice plant.
The liquorice-root extract contains the natural sweetener glycyrrhizin, which is over 50 times sweeter than sucrose. This ingredient has various pharmaceutical properties, the most important ones being that it acts as an expectorant (facilitating removal of mucus from the lungs by coughing) and that it increases blood pressure. The latter effect can become significant with a daily consumption of 50 g or more of liquorice candy for as little as two weeks.

Nataly has some liquorice candies bought. I have heard about such candies so much that when I saw them sold in "Panama" mall I beg my mum to buy them. They are very tasty and healthier than usual candies. The only drawback is its price - quite expensive for sweets (99 rub. per 100g).
