Lavender is also a wonderful herb for anxiety. It can be used as a tea or in the essential oil form.
You can apply it to the neck, wrists, behind the ears, etc. If you need too, the oil can be diluted with olive oil so that it doesn't irritate the skin.
Lavender tea can be made by placing a few tablespoons of the dried (or fresh depending on what you can find) flowers into a cup of boiling water. When the tea has finished steeping, strain it and add honey or sugar for added sweetness. This tea can be used to treat headaches, stress, anxiety, etc.
