A branched shrub of sea buckthorn (Hippophaë rhamnoides L.) is a valuable medicinal plant. Its harvest season usually falls in late August, September and October. After harvesting, the berries can be stored in a cool place until December. The branches of the shrub are ‘caked’ with berries, which are very difficult to peel, hence the Polish name for sea buckthorn: oblepicha. In Russia, it is sometimes called ‘Siberian pineapple’ as its taste is reminiscent of the exotic fruit. Sea buckthorn has small, yellow-orange, round fruits with a characteristic slightly bitter, sour-tart taste. When frozen, they become sweeter. Since sea buckthorn branches are spiky, the whole branches are frozen and then ‘tapped’ to so they can fall off.
Traditionally, the plant is used for tinctures, preserves, syrup and, because of the abundance of pectin, in jellies. Sea buckthorn fruits contain water-soluble vitamins (C, B, including folic acid). It seeds, however, are rich in oil containing vitamins that are only soluble in fats: E, F, K, P, provitamin A and D, as well as anthocyanins, flavonoids, phospholipids, tannins, unsaturated fatty acids, macro and microelements, including manganese, iron, boron.
In Poland, sea buckthorn grows naturally mainly on the Baltic coast, by the mouth of the Vistula River in the east (it is under partial species protection). It can also be found, for example, in the Pieniny Mountains. The plant is grown mainly in the Northeast of our country. Sea buckthorn is sold in the form of juice, seed oil, and pulp. It can surely be considered one of Polish superfoods – a natural vitamin bomb.
