Very exhaustive presentation of an extremely useful herb. You should use the #naturalmedicine for this type of content. It is exactly the kind of post they promote!
And if you don't mind, a minor correction from a Greek :)
It is said that Achilles was using that same herb for his wounded men and that's where the name of the plant came from but not for himself since he was invulnerable (except his heel but that's another story).
