Yeah there are females that can do it, but unlike Tatiana they don't tend to do clean vocals as well. Otep, Arch Enemy, and numerous others do it.

As far as growling. It depends on how you do it as to whether it will fry your vocal chords. I watched that interview in the post with her and it doesn't sound like she is too focused on making sure something doesn't mess them up, so it is hard to say.

Michael Akerfeldt of Opeth does clean and growl and has for more than a decade and his voice is just getting better. I am pretty sure he is careful how he approaches it.

I've heard some things that Tatiana does in some songs that are likely pretty harsh on her vocal chords. Time will tell.
