I recall reading a book about LOTR which says the passage you quoted above shows Aragorn is not all sweetness and light.It is disturbing,but so is Gollum. I fould feel queasy if he were anywhere near me and to be bitten by him,argh! You convey his violence and repulsiveness well as well as showing Aragorn is the decent man we know him to be.

A typo you might want to fix "The healing power of the leaves had final driven "
