In 2011, Clarisa Ru, wife of Santa Barbara Polo Club president Wesley Ru told PEOPLE that Kate was attempting to overcome her allergy.
The Duchess was using a way of exposure to counter it – also known as immunotherapy.
Ms Ru said: “I got a chance to have a conversation with Kate.

“I asked if she was into polo before she met William. She said no.
“But she’s been riding horses for a while and she hopes to play polo one day.
“She said, ‘I’m actually allergic to them, but the more time one spends with them the less allergic you become’.”
The NHS does say that immunotherapy could be an effective way to overcome the allergy – saying that “being given occasional small doses of the allergen” will “help your body get used to the allergen so it does not react to it so severely”.

They said: “This will not necessarily cure your allergy.
“But it’ll make it milder and mean you can take less medicine.”
The Duchess has not yet been photographed on a horse, however if the NHS advice is anything to go by, it won’t be long before she will be back on the saddle.
Although polo may be number one on the list of the Duchess’s favourite sports, Ms Middleton has been known to regularly attend a number of sporting events over the years.
It is somewhat of a tradition for Prince William and Kate, both 39, to attend Wimbledon in the summer over the years.

The Duke and Duchess were even spotted this year at the prestigious tournament won by Novak Djokovic.
The Duke and Duchess were also in attendance for the Euro 2020, with Wembley Stadium being centre stage for the occasion of the final.
After a brave effort from England, the Duke and Duchess would no doubt have been disappointed – albeit proud – as the Three Lions crashed out on penalties to Italy.
