Garlic may assist with:
skin conditions, strengthening the respiratory system, promoting digestion, supporting the circulatory and lymphatic systems, protecting against infectious organisms, like viruses, bacteria, fungi and yeast infections, encouraging circulation, and stimulating the immune system. Garlic can promote the activity of the excretory organs. Garlic has been used to repel hook, pin, tape and round worms internally and insects externally. If it is fed regularly it can assist in keeping intestinal worms at bay. Tail rubbing can be an indicator of pin worms, so feed them some garlic if this is evident. The sweat produced by horses fed garlic has an odour that can keep flies and biting insects at bay. Garlic should not replace the use of regular wormers.
Has been known to irritate the stomach and can be a skin irritant to some. Recommend removing from diet periodically to avoid causing an imbalance in intestinal gut flora (good bugs present in the gut to aid digestion); in excess it can irritate the gut and cause anaemia. Garlic can over load the liver when given in large doses. Care should be taken if you are feeding garlic to a nursing mare as it may taint and come through the milk. This may also upset the delicate digestive system of young foals and bring on colic.
