Buckthorn bush, which grows on the outskirts of the humid forest and, more preferably, along rivers or lakes, may be recognized easily during ripening by its initially red, blackening spherical fruits similar to the size of a pea.
Buckthorn bark is a well-known and proven laxative. Some researches claim that participants of ancient mysteries have purified themselves with buckthorn bark before their devotions. Nowadays it is used more willingly, as in addition to its basic action in chronic atonic constipation, is also effective in abdominal bloating and various liver diseases (inflammation of gland and gall bladder, cirrhosis, jaundice, etc.).
Pharmacies offer Rhelax syrup manufactured by Herbapol Wrocław with buckthorn bark as an active ingredient.
