Several studies report the use of M. sylvestris for veterinary purposes. Decoctions of whole plants, sometimes boiled in oil, can be administered to livestock to treat colic and to unblock rumens. The leaves when applied in enemas or compresses have shown high effectiveness in the treatment of mastitis in bovines and against swine constipation.
Infusions and decoctions of blooming aerial parts have been used as laxatives in horses, but these preparations have also demonstrated activity against inflammation, wound infection, diarrhoea in young calves, respiratory problems in horse, and intestinal inflammation in cows and sows.[99,100] Applied in bath form, it can be used as a galactagogue in sows, and the enema preparation can be used against aphthous fever and as an antiseptic.
By direct ingestion, the leaves have been used as a laxative, as an antimastitic and to decrease ruminal methane production. The crushed plant has been applied externally to drain abscesses in cattle; use as a curative for skin, reproductive and nervous disorders has also been reported.
