Answer:
I can be sweet or sour. I do not rhyme with any other word
A dragon's tooth in a mortal's hand, I kill, I maim, I divide the land.
I had a bright start, but I couldn't take the pressure. I consume everything, yet I don't eat anything. What am I?
I am born in fear raised in truth and I come to my own in deed. When comes a time that I'm called forth I come to serve the cause of need.
What has no beginning, end, or middle?
Break me and I am better immediately set and harder to be broken again.
