Ginger (Zingiber officinale) is one of the most versatile herbal stimulants. It is of great benefit to the intestines, circulation, and stomach.
Use as a tea when you are feeling sick or headachy. It enhances the effect of all other herbs and spices. Make your own ginger honey (organic, cold-pressed) and use instead of marmalade.
Avoid use if you have very high blood pressure, or in cases of extreme inflammation, dry skin, or liver inflammation.
