Cardamom is another spice that also has medicinal properties.  I is a close relative of ginger.  There are two varieties commonly used.  
    Green Caedmon is used to treat teeth and gum infections, to treat sore throat and to help with lung congestion.  It is also used to break up gall stones and kidney stones.  
    Amomum, also called Black Cardamom, is used in traditional Chinese and Ayurvedic herbal medicine for treating many illnesses including muscle cramps, stomach problems, asthma and anorexia.  It can be used to fight bad breath.  If you use garlic for health reasons, or just as a flavoring, Cardamom is reputed to even get rid of garlic breath.
