Turmeric powder deposited on throat and vocal cords?

I was told to diectly put turmeric powder down the throat, and swallow, to cure a sore throat.

I did this some 10 days, but while the sore throat became better, I found it harder and harder to hit the high notes, and some days later, my voice became hoarse, and remains hoarse.

Could this be due to turmeric powder clogging my throat as a paste, and when dry, migrating to the vocal cords, making them sluggish ?

If so, what should I now do to clean up the throat and vocal cords?

Thanks in advance for your time.
