Rosemary is a herb that is often used with chicken, lamb, or game meats as well as fish or bean dishes. It has an intense aroma and was prized apparently, by the Greeks for being good for the brain.
It has light blue or pink flowers and dark green needle like leaves that are silver underneath.

As you can see rosemary contains a lot of calcium and quite a bit of fat but no sugars, phosphorus and acid.
It does however contain a very high amount of vitamin c however which is great.
Because of its calcium and fat content it can only be fed to guinea pigs once a week in small amounts at the most. It is not the best herb for guinea pigs to eat.
