Introduction
Natural medicine provides another toolbox of treatments to help
treat chronic cases of laminitis. Several of the major factors in
helping a laminitis horse are to support their feet properly, correct
the intestinal health, provide nutritional medicine to prevent and
reverse damage to the lamina, and to return the horse's metabolism
to proper balance. When managed correctly, with patience and attention
to detail, most chronic cases can return to reasonable work. The
poorly responsive cases can often be managed and kept relatively
comfortable without the use of drugs.
It is important to remember when treating laminitis with natural
medicine to
approach each case individually.
It can be detrimental to any case to use multiple supplements or
treatment modalities without carefully evaluating the case. Because
a product is natural does not rule out harmful effects or the negative
effects of using too many products and overloading the body. Difficult
cases may require many products, however, they should not selected
carefully.
Clinical
signs
The clinical signs most commonly associated with chronic laminitis
long hair that does not shed out in the summer, weight problems
(over- or underweight) and other signs that many people and vets
call Cushing’s disease. In my opinion, these horses have altered
glucose metabolism, similar to that of human diabetics, and not
Cushing’s disease. Some of the symptoms that may be seen in
the chronic laminitis horse include those listed below. If your
horse shows any of these signs along with the laminitis, he is a
good candidate for the natural treatments in this article.

Insulin
Resistance
A relatively new condition is being recognized in human medicine,
currently called syndrome X. This is a group of symptoms related
to insulin resistance or hyperinsulinemia and an inability for the
cells to transport glucose into them. The disease commonly called
“Cushing’s syndrome” in horses has many of the
same characteristics as syndrome X has in people.
Many laminitis horses have elevated insulin levels in their blood.
The reason the insulin is elevated is that it is not able to get
into the cells. Normally when a sugar or carbohydrate is eaten,
the blood sugar levels increase, insulin is secreted by the pancreas,
glucose is carried into the cells by the insulin and the blood sugar
goes back to normal. In insulin resistance, the cell walls are too
stiff to let the insulin do its job properly. So the glucose, instead
of providing energy for the cells, gets stored as fat.
People that are susceptible to syndrome X are from a genetic type
considered “thrifty” or in horse terms, “easy
keepers.” In this type of individual, horse or human, the
body is very efficient at storing fat for times of need, and in
fact, if fed less, they often become more efficient at storing fat.
In humans much of the fat stored from impaired glucose metabolism
is distributed centrally, especially around the abdomen. Many horses
store their fat in specific places; fat pads on their body and cresty
necks.
The basic protocol in treating people with Syndrome X contains many
of the ingredients used when treating the chronic laminitis horse.
The idea is to help make the cell walls more permeable to insulin
and to provide nutrients to help the insulin and glucose pathways
function better.
Intestinal
Health
Horses with laminitis are often in extreme amounts of pain. Consequently
high doses of non-steroidal anti inflammatories (NSAIDs) are used
over long periods of time. Research has been done regularly on NSAIDs
effects and toxicity in the horse as well as in humans. One recent
equine study showed inflamed small and large intestinal walls after
12 days of phenylbutazone administration.
Since high doses of the NSAIDs are detrimental to the integrity
of the intestinal wall the drugs may contribute to a leakage of
bacteria across the wall that triggers part of the breakdown of
the laminae. Consequently, the use of NSAIDs in treating laminitis
should be questioned. Clinically, in my experience the removal of
the NSAIDs is one of the most important aspects of the success of
the holistic treatment. The horses' symptoms are usually worse for
three to five days after removing the NSAIDs, so they lie down more.
That can be alarming to the owners and attending veterinarians,
however, it is best for the horse, since the pressure is off the
feet. The antioxidants can then work. When a horse feels better
with natural medicine it is because he is better, not because the
pain is masked.
Clinically I have found laminitis horses respond best when an attempt
is made to repair the damage done by NSAIDs.
Nutrition
Nutritional support is critical in the laminitis horse. Nutrition
includes the basics of feed, water and hay as well as specific nutrients
for particular problems. As more experience is gained with new products,
additional helpful or even critical nutrients may be discovered.
The nutrients discussed here are ones I have found useful and are
safe for the owner to administer. Complex cases that do not respond
to treatments listed here, need the help of an alternative medicine
veterinarian (see the links for organizations listing practitioners).
Feed
Once the digestive system is supported, high quality nutrients should
be provided. The nutritional requirements for horses with laminitis
are higher and often very specific. Horses with laminitis need high
fiber, low carbohydrate diets. Wheat bran mashes are good for overweight
horses. The small amount of bran needed for these horses may not
upset the calcium phosphorus ratio, though the entire diet should
be evaluated to keep it balanced. Blue-green algae can be added
to the bran mash to provide amino acids and trace minerals and support
hoof growth. Grass or other lower protein hays can be given free
choice. The horse can have some alfalfa along with grass hay, especially
if more protein is needed, but generally alfalfa should not be the
only hay received.
The feed should be low in sugar, so all sweet feeds should be avoided.
Read the label, if any sugar, corn syrup or molasses is present,
do not feed it. When evaluating the feeding program be sure to look
at the treats being given. Apples are better than most other treats
as they contain fructose which is less of a problem than other types
of sugar. Carrots may be desirable for some horses as a natural
source of beta carotene. Plain corn (about 25%), barley (about 35%)
and oats (about 45%) make a simple, clean mixture without sugar.
Some of these grains may not be available or desirable to use in
certain parts of the country or in certain years depending on the
harvest situations. Some horses may not do as well on oats; if that
seems to be the case, just use barley and corn.
Higher levels of protein (up to 14%) and calories may be needed
in the horses with weight loss problems. Laminitis horses that are
normal weight or underweight often do well on the senior diets,
which are high fat. Many chronic laminitis horses lose weight due
to the stress of walking in pain and actually need increased amounts
of feed. Since these horses did not founder due to grain or carbohydrate
overload, it makes no sense to restrict their calories, when they
actually need extra calories to maintain weight.
Increased calories can be given as fats (vegetable oils, rice bran
oil, or rice bran) and are well digested by most horses. Animal
fat should not be used due to the preservatives added in the processing
and the fact that horses are vegetarians and should not eat animal
products. Increasing total calories by adding oil and more grain
may be preferred to using high-protein feeds and hays, though some
horses actually do need the higher protein.
Processed grains and hays may lose key ingredients during manufacturing
since pellets and extruded feeds are made at high temperatures.
In some cases horses have difficulty digesting processed feed, yet
in my experience, when horses are fed plain grains they generally
gain weight and are healthier. Some horses need digestive enzymes
added to their food to aid digestion.
Antioxidants
Laminitis is a classic example of free-radical damage. High levels
of anti-oxidants are needed until this process is reversed, then
lower maintenance levels can be used. Using low doses of antioxidants
over time is like trying to put out a forest fire using a garden
hose. Over the counter, combination antioxidant products rarely
have enough of any one ingredient to reverse free-radical pathology.
Coenzyme
Q10 is very valuable in reversing free radical damage. The
therapeutic dose is 300-600mg per day for the first week or two,
then the dose can be decreased slowly to a maintenance of about
100 mg per day.
Coenzyme
Q 10 clinically seems to be one of the best antioxidants for
use in the horse, and in laminitis cases can be so effective that
the horses become more comfortable rapidly.
Co
Q 10 is most effective in laminitis cases when non-steroidal
anti inflammatories such as phenylbutazone (NSAIDs) are not used.
However, in many cases the owner is using the NSAIDs because the
horse is at home and the attending veterinarian prescribes them.
Co Q 10 can be used with the NSAIDs but the results are not visible
clinically.
Vitamin C is an excellent antioxidant and nutrient for collagen
support as well as organ and immune system healing. Doses range
from 3 to 8 gms per day. Horses tolerate these doses well with few
cases of diarrhea or stomach irritation.
MSM is a natural source of the antioxidant mineral, sulfur. It is
also a mild diuretic. Sulfur is important as it helps make up the
disulfide bonds in the laminae. The disulphide bonds are an important
part of the connects the hoof wall to the healthy lamina.
Other antioxidant nutrients that can be useful are Vitamin E and
superoxide dismutase (SOD). These antioxidants are generally used
in the more difficult cases.
Minerals
One of the most important aspects of any nutritional program for
horses is the use of free choice minerals, with the salt fed separately.
If a commercial salt-mineral block is fed (about 94% salt), the
horses cannot consume the amount of minerals they need. A laminitis
horse will generally eat large quantities of minerals, when the
salt is removed, for extended periods of time indicating their need
for minerals. Sulfur may also be an important nutrient for these
horses and can be fed free choice or in a supplement such as MSM.
There are several key minerals needed for glucose
metabolism that help the Cushing’s horses. Magnesium affects
insulin secretion and its action in the cells. Magnesium also helps
the cells be more flexible and permeable to insulin. Chromium helps
make muscle more sensitive to insulin so glucose can be taken into
the muscle cells more easily. Chromium is also related to elevated
blood sugar and has been shown to be effective in reducing fasting
blood sugar levels. Vanadium or vanadyl sulfate has actual insulin-like
effects on glucose metabolism which helps transport glucose into
the cells.
Vitamins
It is important to supply high quality supplements. Prepared foods
cannot have all the vitamins needed by a sick animal. However, formulated
supplements which contain low quality, synthetic vitamins, inorganic
minerals, and fillers may actually cause the horse's system to become
more out of balance. Food-source vitamin mineral supplements include:
blue-green algae, kelp, apple cider vinegar, carrots, and oranges.
Several companies manufacture additive-free supplements.
Essential fatty acids
Essential fatty acids (EFA’s) are needed to help make the
cell wall more permeable to insulin. The Omega 3 fatty acids are
especially deficient in human diets and may be deficient in many
equine diets. Most of the high fat equine foods use animal fat that
is high in saturated fats and full of preservatives. Flax and hemp
oil (or flax seed that has been stabilized naturally, not chemically)
provide plenty of Omega 3 fatty acids that are palatable to the
equine. Some horses’ symptoms improve with just the addition
of fatty acids to their diet.
Homeopathy
I use constitutional homeopathic medicines selected according to
the symptoms the individual is exhibiting. Homeopathy is important
to the success of the treatment in many cases. You, as the owner,
must be patient enough to work through a case properly with homeopathy
and it is necessary to work with an experienced homeopath. Constitutional
homeopathy needs be prescribed based on the history, clinical signs
and personality. It is not possible to cover the details or remedies
here.
Chinese
Medicine
Chinese medicine, both with acupuncture and herbs can be used to
help laminitis horses. It is best to work with a veterinarian experienced
in either herbs or acupuncture. The International Veterinary Acupuncture
Society and the American Academy of Veterinary Acupuncture have
lists of qualified practitioners.
Western
Herbs
Aloe vera is a nutritional herb, which will support healthy bacterial
growth and help heal the damaged intestinal lining. Expect to pay
$10.00-$12.00 a quart for good quality aloe, and feed at a rate
of 2-4 ounces each feeding for 2-4 weeks.
Slippery elm bark is another nutritional herb, which protects and
aids in healing the intestinal wall. It is especially useful with
aloe vera to heal the intestinal irritation secondary to the use
of non-steroidal anti-inflammatory drugs such as phenylbutazone.
There are some formulas designed to improve circulation in the feet
that may be very useful. Some of the “Cushing’s”
formulas may be helpful, but probably are not as effective as many
of the other therapies listed in this paper.
Vaccinations
I would recommend not vaccinating or decreasing the vaccination
program to the absolute minimum for the chronic laminitis horse
to decrease stress on the body. Vaccine titers are available for
most diseases, and most horses tested seem to be maintaining good
titers from previous vaccinations.
Environment
Many horses are kept in high stress situations and it is important
to decrease environmental stress as much as possible. Some of these
horses may be past their high-stress years, and not be showing but
the previous lifetime of stress, overvaccination, excessive drug
use and poor nutrition are catching up.
Pasture turn-out time is very important; however it is common for
a laminitis horse to be unable to have rich pasture without worsening
symptoms. Do not to fertilize your fields or mow and manage them
too carefully. Natural fertilization with trace minerals is a good
practice, though if grass becomes too rich even from good organic
practices an overweight horse will result. A few weeds (herbs) are
a good thing. For many horses a “fat pen” will need
to be built, just a small area outside with minimal grass so they
can be out in the sunshine and near their friends, but not have
too much grass. Most horses will adapt to wearing muzzle, which
limits the amount of grass in each bite, yet allows more exercise
and companionship staying with the herd.
Conclusion
Prevention is still the best way to manage laminitis in horses,
however, chronic laminitis cases can recover with a multi-faceted,
long-term natural treatment plan. Treat each horse as an individual
and seek quality practitioners to help you.
