Further Possibilities - For Pets
While we were researching for this book, an Irish pharmaceutical manufacturer
and importer told us how he came to include grapefruit seed extract in his inventory:
"I had ordered several samples of the extract, and when my hunting dog
got a bad fungal infection, 1 took advantage of the opportunity to try out the
extract. Two days later, there was no trace of the fungus to be seen. The vet
asked me in astonishment what I had done with the dog. When I told him about
grapefruit seed extract, he pressured me until I gave him my entire supply of
samples. Unfortunately, I then no longer had any myself and a new supply was
far away. Now I carry grapefruit seed extract in stock and therefore always
have my own supply on hand."
After this experience, he began his own investigation of the effects. When we
called him four weeks later, he said: "I am positive that we are dealing
with the most interesting broad spectrum therapeutic agent of the future. I
don't know of any other comparable remedy, and it also appears to be superior
to tea tree oil."
The healing of his hunting dog was just one of the many reports that we have
received on the extract's suitability for animals, which arrived with increasing
frequency. There are no plausible reasons why grapefruit seed extract, which
can be used with such success for human beings, shouldn't work on animals as
well. The physiology of most mammals is quite similar to our own.
Soon we also had the opportunity to try out the extract on an animal. Our cat
Ananda got a stubborn fungal infection on his head. We observed it for a while,
and when it continued to spread, we applied grapefruit seed extract twice a
day. It took a while for the fungus to disappear completely, but the symptoms
began to recede from the first treatment.
Our dog Shanty was the next "guinea pig." Almost all dogs and cats
suffer from intestinal parasites and should be wormed on a regular basis. When
it was once again time for Shanty to be treated, he showed all symptoms of worm
infestation. We have to admit that we were delighted every time there was an
opportunity for a further experiment.
However, we did not know the correct dosage for animals. So we put a capsule
with 125 mg of grapefruit seed extract into his food every day for a week. He
ate it without any difficulties. One day a capsule opened and the powder landed
in his feeding bowl. He enjoyed his food all the same and the bowl was empty
in no time. Next we tried and mixed 10 drops of the liquid extract into our
cat's favorite meal, and his feeding bowl was also quickly emptied. We repeated
the treatments after two weeks, and then again after four. All that we can say
is that the extract was at least as effective as the chemical vermifuges.
Today we know that half of the administered amount would have been enough for
our medium-sized dog, and our cat had received an even bigger overdose. Fortunately,
grapefruit seed extract only leads to severe poisoning with a 4000-fold amount
of the required dose, so you can hardly go wrong. We know of some pet-owners
who give a preventative dose on a regular basis. It should be about half as
much as for the treatment of disease.
Although it is difficult to give too large a dose of grapefruit seed extract,
the optimal daily dose for animals can be determined. In order to make it easier
for our readers, we have compiled a table for this purpose at the end of this
We had just finished this table when a neighbor, who had also used the extract
for her dogs and cats, visited us. We proudly presented her our new work, which
she glanced at skeptically. We then heard the friendly old lady's somewhat biting
comment: "That's nonsense! Your table is much too complicated. Every one
of my animals gets a capsule of grapefruit seed extract every day and that's
it! And it works. Since I started doing this, the animals haven't been sick
once. I can't start working out amounts every time-where would it end!"
In a sense, she was probably right. Since grapefruit seed extract can only lead
to severe poisoning at a 4000-fold dose, her animals showed no harmful side-effects
whatsoever. We later checked the figures and discovered that she had given her
cats (just as we had our Ananda) about 10 to 15 times the necessary amount-without
any problems. But such an approach can be expensive. If you only have one dog
or cat, the cost factor may play a minor role. Things look different if you
operate a dog kennel with 30 animals or have 600 sheep grazing in the meadow.
Similar to its uses for human beings, grapefruit seed extract can be applied
to a broad spectrum of diseases in our four-legged friends. It has proved to
be an excellent remedy for skin diseases, external injuries, and fungal infections.
Internal diseases caused by bacteria, viruses, or fungi also react well to the
extract. However, since an animal can't tell us what's wrong, it might be impossible
to clearly diagnose the cause of an internal disease. It is well worth trying
grapefruit seed extract since in most cases symptoms often subside with surprising
Based on the experiences of many pet-owners, we recommend the following treatments
for the individual diseases:
For internal health disorders due to parasites, bacteria, or fungi, put the
dose specified on the list into the food. If the animal is no longer eating,
try putting the less bitter powder into the drinking water.
Skin fungi or bacterial diseases of the skin can be sprayed with a solution.
For this purpose, put 30 - 40 drops into 1 liter (35 fl. oz.) of water and pour
into a spray bottle. Please make sure that it doesn't get into the animal's
eyes. The extract can also be mixed with shampoo (about 10-40 drops, depending
on the size of the animal). Shampoo the fur thoroughly with the mixture, and
let it take effect for several minutes. Repeat the process after 3 days. For
smaller areas and in stubborn cases, a few drops of grapefruit seed extract
can be applied in full-strength or mixed with a little glycerine twice daily.
However, please make sure that the animal does not lick this highly concentrated
mixture and consequently damages its more delicate mouth mucous membranes.
Grapefruit seed extract can be used as a wound disinfectant for external injuries.
It is best to use the spray described under "Skin Fungi" for this
purpose. For weeping wounds, the grapefruit seed extract powder (commercially
available up to now only as "grapefruit seed extract foot powder")
has proved to be effective. If the animal suffers from a fungal disease in the
mouth, spray diluted grapefruit seed extract (20 - 30 drops in 1 liter of water)
directly into the mouth with a spray bottle- but no animal will like this.
For sick birds, we put a very small amount of the liquid grapefruit seed extract
into the drinking water (mix well) or add a bit of extract powder to the seeds.
Birds also frequently suffer from inner parasites, which can be eliminated in
this simple way.
Add liquid grapefruit seed extract to the water for fish in the aquarium. Mix
well. Start with 5 drops to 1 liter (35 fl. oz.) of water and slowly increase.
The algae infestation, seen on the glass walls, should decrease as a result.
If you use ready-made grapefruit seed extract, always pay attention to the information
and recommendations on the packaging. In case of doubt, consult an experienced
veterinarian or animal health practitioner.
In addition, grapefruit seed extract is ideal for the disinfection of cages.
You can spray or wipe them out with a solution of 20 to 30 drops of grapefruit
seed extract in a bowl of water.
Feeding troughs and bowls, as well as the sleeping places of dogs and cats,
can be disinfected with this solution. For washing basket pads, dog blankets,
etc.. put 20 drops of the extract into the last rinse.
So far we have heard of no negative reactions after using this extract on animals.
If you are successful with your own experiments and would like to share your
experiences for the benefit of other animals, why not publicize your results
in the relevant publications or inform the animal welfare organizations about
them. You may also contact the "Grapefruit Seed Forum" for the purpose
of stimulating further research, distribution, or publication! (See "Appeal
for International Cooperation" for address.)
