Q :My warmblood mare has what I was told was a blocked tear duct in one of her eyes. The eye is always running and she has tear stains, for want of a better description, on her face all the time from that eye. The liquid is clear and doesn’t appear to be infected in any way. Is there anything I can do for her? It seems that it’s just an aesthetic thing, but it can’t be that comfortable for her.
AA, Maniototo

A :Tears are produced all the time to lubricate and protect the eye. Excess liquid either evaporates or is drained away into the sinuses. Blocking of the drainage ducts is not uncommon and as you say is really no more than unsightly. The cause may be a blockage or an overactive lachrymal gland.
One thing which may work – it doesn’t always – is to wipe a moist tea bag over the eye. A used one is fine. Tea contains high levels of tannins which tighten the tissue. You may need to do it every morning but it is pretty easy to do.
If you know a local herbalist you may be able to get some eyebright. By its name this is a favourite eye herb. Use it as an infusion but be careful to keep it fresh. The last thing you need is to introduce an infection into the eye. It is not easy to get drops into a horse’s eye so a moist pad may help.

eye Eyebright is a useful herb to use as an eye tonic

Q :My horse has been diagnosed with a trapped nerve in his hip, which has been fixed (I hope) with a chiropractic manipulation. It’s going to take some time to get him to start using himself properly, though, as the injury has been there for some time. I was wondering about herbal/nutrition support for his rehabilitation and for the nervous system generally. Thanks.
Mandy, Waikato

A :From what you say it seems that this condition had been continuing for some time, so a regime of exercise and perhaps ongoing manipulation may be necessary. There is a group of herbs known as nervine tonics which will help, but there are a couple of other things that you may like to consider.  When you start working him again he will probably be a bit stiff and sore. I’d suggest devil’s claw for its anti--inflammatory properties, and schisandra to help any lactic acid build up. He may also be a bit sore after manipulation. Devil’s claw will really help here but please discuss it with the chiropractor.
Nervine tonics include oat straw and St John’s wort. They will help support the nerve tissue as it recovers from the pinch. Nerve tissue is very slow to recover so do not expect quick miracles.
For horses the easiest nervine tonic is probably oat straw. Put a good handful of oat chaff into a litre of water. Boil it for about 10 minutes, allow to cool and then add it all, liquid and solid, to his feed. Silica is a very important mineral for nerve health and decocting the oat straw releases it for absorption by the horse. You may need to give him this much twice a day for up to three months, but it should certainly help.
In situations like this it is a good idea to make sure you include a wide range of nutrients in his diet. Kelp is a great source of a wide range of trace and ultra trace elements and is easy to source. You may also like to consider dried nettle. This is used in humans as a spring tonic and contains a wide range of minerals as well as being anti-inflammatory.

Q :Like many horses, my TB loves peppermints of any kind. That led me to wonder about feeding mint (the garden herb) or peppermint directly, so as to avoid the sugar and other processed ingredients of Oddfellows and so on. Are there any health benefits of mint for horses, or do they just like the taste? Is it harmful for him to eat a whole packet of peppermint lollies?
Minty, Southland

A : Peppermint is one of a group of herbs known as carminatives; they are used to relax the stomach and aid digestion. Hence the use of peppermint tea by humans. The flavour of peppermint lollies is derived from peppermint essential oil, which is made by steam distilling the fresh herb. Giving peppermint lollies to horses in moderation should cause no problems. Too many may not only give too much sugar but may also cause over relaxation of the sphincter muscles which are important in the functioning of the gut. We have not used garden mint as a therapeutic herb but in the UK mint siftings are very popular as an ingredient in many dry herb mixes. I suspect it is used as a filler; mint siftings are cheap. If your horse likes the taste of garden mint I would not hesitate to give it to him; fresh or dry as suits you. It has mild carminative properties but is really just a flavour herb.
There are many different varieties of mint but the medicinal variety is mentha piperita.
There have been several interesting studies on its effectiveness in inflammatory bowel disease, gut spasm and upper respiratory infection. You will also be familiar with menthol, which is one of the constituents found in peppermint.
Once you have sourced the correct plant it is very easy to grow. Just like garden mint it needs plenty of water. It tends to have a more seasonal growth pattern producing most of its new leaves in the spring. Pick and dry it then and you will have a free source of peppermint all year.

Q :I have a thoroughbred-cross who has typical (bad) TB feet with thin soles and crumbling walls. He usually keeps his shoes on okay, but he has constant problems with stone bruises and hoof abscesses over winter. My farrier has shod him with pads, and I try to yard him for a part of each day so his feet can dry out, but I was wondering if you would recommend anything natural that I could feed him to help improve his feet. What about when he has an abscess – is there anything that will help heal him faster, either that I can feed him or use as a poultice?
CM, Auckland

A :General hoof health is helped enormously by rosehips. We treated a warmblood horse a few years ago whose feet were so bad that the owner was seriously considering putting him down. His feet were so soft and crumbly that he could not be shod and equally could not go barefoot.
After three months feeding rosehips the farrier thought the owner had bought a new horse!
It will take a while as the new hoof mat-erial grows down from the top but the difference will be remarkable. For a normal sized TB, 30 grams a day should be sufficient. Just get the dried granules and add it to his feed.
Abscesses are an indication on a lowered immune system.
Improving his hoof health will help but you may also like to think about echinacea to support the immune system.
Circulation to the feet is not as good as to some other parts of the body, so adding some powdered ginger to the feed will also help. Add about a teaspoonful a day to his other feed. When he has an acute abscess, a poultice of cabbage leaves will help to draw out the contents and cool the hoof.
