Links?

Here's one for magical uses, not so much for injuries. You can get a lot of info about herbs from Wiccan sites, though not all that reliable.

I really haven't checked any of these out beyond making sure that they should, at the very least, point you in the right direction.

http://www.answers.com/topic/herbalism (Looks to be an interesting read, but if you are just looking for your answers scroll down for examples of specific herbal remedies.)

http://www.rootdown.us/Herbs/Browse.aspx (Another bookmarked site.)

http://www.answers.com/topic/list-of-medicinal-herbs

http://www.answers.com/topic/list-of-herbs-and-spices (And yet another new bookmark.)

I could find more, but these should help....at least I hope. I have to stop now. I will add too many new bookmarks in my own research directory.

The only website you'll ever really need for herbal information: Mrs. Grieve's Botanical

As to closed head injuries, are you looking for herbs to be used to address internal swelling/bleeding, or are you looking at those that might treat the later results of TBIs, such as memory loss, headaches, depression, etc? Let me know, and I'll see what I can dig up in my reference books.
