ABSTRACT
Sosnowsky's hogweed (Heracleum sosnowskyi Manden.) is a genus of plants in the family Apiaceae which also includes Giant Hogweed (Heracleum mantegazzianum Sommier and Levier). They are both found in Central Europe, mainly in neglected green areas or riversides. Sosnowsky's hogweed was brought to Poland from the Soviet Union in the 1950s to be used in animal feed production. Intended goals couldn't be achieved and the plant spread throughout grounds distant to the primarily cultivated lands. Sosnowsky's hogweed is especially hazardous in direct contact with human skin. It results from the content of photoallergic substances called furanocoumarins in its essential oil. Clinically it is presented as burns, mainly of 2nd and 3rd degree. They mostly occur on the face, upper and lower limbs. Typical symptoms include pain, redness, swelling and heat in the area of exposure. Their extent depends on burn's depth and area and also on time of exposure to plant's toxins. In this article we present Sosnowsky's hogweed's activity and its influence on human health.

Betel is a kind of substance for chewing, that is made from piper betle, areca nuts and other, additional constituents. It is the fourth most popular psychoactive substance in the world, right after caffeine, nicotine and alcohol. It is particularly famous in Asia. Betel chewing induces euphoria and it is addictive. Similarly like in other substances such as nicotine or alcohol, betel also has detrimental effects. It causes e.g. oral cancer and cancer of the oesophagus, it contributes to the development of metabolic syndrome, liver cirrhosis and chronic kidney disease. There are also positive effects of chewing betel, because is has antioxidant, anti-inflammatory, antyparasitic and antiseptic properties. The aim of this paper was to expand knowledge about betel and its both: positive and negative influence on human health. In this article original and review papers associated with the topic were used.
