Tea Question

Pesach
1

I blend my own tea throughout the year. I had a bag of pure whole leaf green tea, a bag of pure peppermint, and a bag of pure spearmint (both of the mints are just cut leaves). Question one is can I use them on Passover? Question two is can I continue to use the opened bags from during the year?

Thanks!

1- yes
2- as long you you’ve been careful to not contaminate them with chamtez, yes
