The name cardamom (sometimes written cardamon) is used for species within two genera of the ginger family Zingiberaceae, namely Elettaria and Amomum.

Types of cardamom and their distribution
The two main genera of the ginger family that are named as forms of cardamom are distributed as follows:

• Elettaria (commonly called cardamom, green cardamom, or true cardamom) is distributed from India to Malaysia.
• Amomum (commonly known as black cardamom, brown cardamom,

Uses
All the different cardamom species and varieties are used mainly as cooking spices and as medicines. In general,

• Elettaria cardamomum (the usual type of cardamom) is used as a spice, a masticatory, and in medicine; it is also sometimes smoked; it is used as a food plant by the larva of the moth Endoclita hosei.
• Amomum is used as an ingredient in traditional systems of medicine in China, India, Korea, and Vietnam.
• Can be used as a traditional flavouring to Turkish coffee.

Uses in cuisines around the world
Cardamom has a strong, unique taste, with an intensely aromatic fragrance. It is a common ingredient in Indian cooking, and is often used in baking in Scandinavia [citation needed]. One of the most expensive spices by weight, little is needed to impart the flavour. Cardamom is best stored in pod form, because once the seeds are exposed or ground, they quickly lose their flavour. However, high-quality ground cardamom is often more readily (and cheaply) available, and is an acceptable substitute. For recipes requiring whole cardamom pods, a generally accepted equivalent is 10 pods equals 1½ teaspoons of ground cardamom.

In traditional medicine
In India, green cardamom (A. subulatum), or "elaichi," is broadly used to treat infections in teeth and gums, to prevent and treat throat troubles, congestion of the lungs and pulmonary tuberculosis, inflammation of eyelids and also digestive disorders. It is also reportedly used as an antidote for both snake and scorpion venom.

Species in the genus Amomum are also used in traditional Indian medicine. Among other species, varieties and cultivars, Amomum villosum is used in traditional Chinese medicine to treat stomach-aches, constipation, dysentery, and other digestion problems. "Tsaoko" cardamom is cultivated in Yunnan, China, both for medicinal purposes and as a spice.
