They are short-stretch bandages containing a paste of zinc oxide and other active substances (natural coumarins, glycerol, calcium chloride, etc.). They are employed in the treatment of venous disorders – e.g. in postphlebitic syndrome – or in lymphatic disorders, for example in acute and chronic lymphangitis, in particular owing to their anti-inflammatory, antibacterial, exudate-absorbing activity, hence for their trophic effect on tissues involved by irritative-dystrophic processes.
