Lemon Verbena has a lovely citrus scent and is useful to plant around stables to deter flies and mosquitoes. It can also be made into a natural fly repellent with other scented herbs or just put a few drops of the oil in water and spray around the stable and lightly around your horse. As always, test a small patch of skin first as the occasional horse may be allergic to anything.
Medicinally Lemon Verbena has traditionally been used as a sedative, to help with stomach problems such as indigestion, flatulence, for skin problems and colds with a fever. It is known for being very soothing for the stomach as well as lifting the spirits and helping with depression.
