Urk. That's not as helpful as a paper Liddell & Scott, which gives each form in its alphabetical place. There's a word taraxis 'disturbance' from this root. As there's a form tarattesthai with -tt-/-ss- then there might be an alternative tarassis from the same root.

But I would have thought as 'hysteria' is from 'womb' the male equivalent would be something more obvious... erm... orchidia, anyone?
