This discussion was one of many that led me to try toothpaste on sarcoids. My horse was diagnosed by a vet, had biopsy taken and confirmed sarcoid. I am the sort of person that will do anything for my horses and will go without food and heating to pay a necessary vets bill. I was quoted around £400 pounds (UK) for Liverpool cream treatment which was affordable but since the sarcoids were fairly small (biggest one about the size of a thumb-nail) and my vet had said that one option was to leave them be, I decided to experiment. I am a scientist by background and I'm generally sceptical about 'miracle cures' but there were so many people with claims that toothpaste works that I thought there might be something worth investigating.
I tried Colgate Duraphat 5000 toothpaste - available online or from some dentists which was the highest fluoride content i could find. I applied this once a day, always giving the area a wash with a soft brush to remove the gunge before hand. Within 4 weeks the smaller sarcoids had gone hard and flaked off like scabs, and within 6 week later the biggest one just fell off leaving healthy-looking pink skin behind.
While being really pleased that I seem to have a success, I am still quite unsure as to the effectiveness of this treatment. Part of me worries that I have experimented with clinically unproven treatment on my beloved horse. I don't know if the sarcoids will come back - maybe bigger than before. Will the same treatment work again? - I just don't know.
I would like to see a proper clinical trial on sarcoid treatment, comparing the vet's recommended treatment compared to toothpaste, other 'herbal' cures, and doing nothing. How long does each take to work? Does the treatment cause the horse discomfort or pain/swelling? What are the long-term outcomes? Does fluoride content matter? This could be a nice project for a student vet - if you could get 500-1000 horses involved in a trial the results could be quite interesting - maybe there could be some funding from a toothpaste manufacturer.
Anyway, enough of my ramblings, I wish you success with whatever sarcoid treatment you decide to use.
