Blueberries are great for your health and taste delicious, too. They are one of the most popular berries that people eat. In addition to their great appearance and taste, they also have wonderful medicinal properties. It is well known that eating blueberries makes you stronger and protects you from illness.
There is obviously no need to explain what blueberries look like. However, we may need to talk about distinguishing them from bog bilberries (another natural species that belongs to the genus Vaccinium). These two plants are rather different from each other. First of all, blueberry plants are light green, while bog bilberry plants are blue-green in colour. Secondly, blueberries are dark blue or almost black, but bog bilberries are clearly light blue. The shape of the berries is also slightly different: blueberries are round; bog bilberries are oblong. Thirdly, the shoots of blueberries differ from those of bog bilberries, being light green and sharply square in shape in the first three or four years. Lastly, bog bilberry shrubs are much bigger than blueberry shrubs.
Blueberries taste better than bog bilberries and they are also more valuable to your health. Blueberries are among the best berries found in our forests, and in July you always see people picking them in good blueberry areas. They have an impressive range of uses: they can be used to make jam, juice, kissel or compote. However, fresh blueberries are the best. They are often eaten with sugar and milk. The berries can also be dried. To do this, the berries must first be left in the sun in a single layer for a couple of days. They are then brought inside and dried on a stove, in an over or in a drier. The drying temperature should not be higher than 60 °C, as many of the good substances in the berries perish at higher temperatures. Blueberries that have been processed like this are used as medicine. They help treat various digestive disorders – including the simple but extremely uncomfortable diarrhoea. They have this effect because they contain tannins. Blueberries and the leaves of the blueberry shrub can also be used in leather tanning due to their high tannin content. The leaves, which contain more tannins than the berries, are used as medicine.
