It really does work!! we have a mare a youngster,who developed a very distressing sweetitch, and we tried many ungents ,potions ,and feed additives,all to very little if any ,benefit.We had steroids given by the vet at the end of last season,which did help so much,that we thought we would dive straight into steroids this year when she started to scratch again. they had little effect.looking about for anything else we hadnt yet tried ,i came across "Flyfree" with the addition of turmeric and garlic,-the turmmmeric helping with the inflammatory sympton,and the garlic for excretion through the skin to repel flies and midges,-and she is oozing sores free now! there is still and occasional itch,but ,her mane is intact,and her tail is growing back.It really does work.
