Boric acid use by doctors

I went to the ear nose and throat doctor today for a ear problem and he "puffed" boric acid powder into my ears that was in a clear glass bottle with a metal horizontal straw that puffed the white powder. Is this usually pure boric acid powder or do they dilute it with cornstarch or baby powder or something. It seems like it would be too strong to use the pure stuff but what do I know.
