After reading my friend Crones post this morning on how to make our own flower essences, I thought I would expand on this and refer you also to Bach flower therapy, which she also mentions in her post.
During the time when I was trying to heal myself, I also learned about Bach, I purchased their book and learned lots of good things. I always wished I had the money to search out a good homeopathic healer to use things like this for healing instead of only regular doctors that my insurance will pay for.
Here is their main site online http://www.bachflower.com/
a list of articles http://www.bachflower.com/Articles.htm
on this site you will find lots of books as well, perhaps your library may have a few
From about.com I found a very informative post http://healing.about.com/od/floweressences/a/nature-remdies.htm
and more on how to make your own flower essence, which my friend explains as well in my first link
and I found this video
