**7.2 Flax/hemp wound dressing**

The study on the effective implementation of inherent antibacterial and antioxidant properties as well as high ability to liquid sorption of bast fibers for medical target resulted in the development of flax/hemp wound dressing. The investigation is protected by patent [46]. Carefully selected flax and hemp variety characterized by high phenolic acid content as well as the use of determined fiber processing that allows us to keep the bioactive substances in the fibers on proper level leads to obtain bioactive textile suitable to wound dressing when the structure of dressing is developed accordingly.

The developed flax/hemp wound dressing was clinically tested with patients under care of surgical clinic suffering from nonhealing venous ulcers of legs and diabetic wounds. One of the examples of the efficiency of linen dressing is nonhealing venous ulcer of the right shin of the one patient. Before linen dress application, the patient was treated with using different medicines for three years with no success (antibiotics and ointment). After the application of treatment by the linen dress, the duration of healing was 4 months.
