[Experimental studies on the action of extracts of herba recens Echinaceae purpureae on skin flaps].
In animal experiments the effects of Echinacin, a sap made from Herba recens Echinaceae purpureae, on the rate of necrosis of skin flaps were studied in comparison with NaCl and pentoxifylline. The fluoresceine test was used as an indicator of peripheral circulation. The noncirculated area of the skin flap was significantly smaller in Herba Echinaceae treated animals than in control animals (p less than 0.01). On the day of the operation the size of the noncirculated flap area was only 56.0%, whereas it was 77.8% in the NaCl group and 67.4% in the pentoxifylline group. Until the 5th postoperative day the ratios changed to 47.4% (Herba Echinaceae), 76.6% (NaCl) and 50.4% (pentoxifylline). While more than two thirds of the skin flap area were to become necrotic in the NaCl group, less than half of the skin flap was so in the Herba Echinaceae group. Thus Herba Echinaceae significantly decreased the rate of necrosis of skin flaps in animal experiments.
