Do you know of a good comprehensive database of spices, herbs and peppers?

I am looking to expand my cooking and flavor reportoire.

What I would like to find is a database that contains a full list of spices a description of the taste and flavor, as well as what it is commonly used in or on. Any additional information about the history and or researched and vetted health benefits would be a bonus. Actually it might be better to have a dish with a list of spices that are commonly associated with that dish and so forth.

I have been able to find one or directories. But they were incomplete and hard to navigate. I was wondering if there was something available that was more user friendly.
