Therapeutic uses: Cardamom is known for its stimulating qualities and soothing effects on the gastrointestinal system. The tea is taken all over the world for flatulence, bloated stomach, sluggish digestion, irritable bowel syndrome, and gastritis. In Thailand, Siamese cardamom and bastard cardamom are used to ease stomach pain and cramping associated with gastritis and indigestion. Cardamom is also widely used as a cough suppressant, as well as to treat colds, bronchitis, asthma, and laryngitis.
Preparation: Make powder from dried seeds. Take 2 tsps in warm water or in herbal tea after meals. For cough, drink tea or suck on whole seeds.
Allergic effects: Patch test reactions to cinnamic aldehyde were found in 11/25 factory workers, but in several cases, the nature of the reactions was difficult to evaluate.9 Irritant patch test reactions were seen from powders of cardamom, paprika and white pepper. On prick testing, 6/25 workers reacted to cinnamic aldehyde. The results illustrate the difficulties of patch testing with spices and indicate the need for further research and validation of methods.
