From the Manufacturer:
Cardamom oil is obtained by steam distillation of the aromatic, fragrant seeds. It has a warm, subtle, and spicy scent which is used a great deal in floral perfume compositions. In massage oils, cardamom seed invigorates the muscles without irritating the skin. It's a great choice for those with sensitive skin.
The seeds can be used, coarsely ground, in pot-pourri and herb pillows. They are used in paan, the seed and spice mixture served after meals to help digestion and freshen the breath.
