Young ginger rhizomes are juicy and fleshy with a very mild taste. They are often pickled as a snack or just cooked as an ingredient in many dishes. They can also be steeped in boiling water to make ginger tea, to which honey is often added. Sliced orange or lemon fruit may also be added. Ginger can also be made into candy. Mature ginger roots are fibrous and nearly dry. The juice from old ginger roots is potent and is often used as a spice in Indian and Asian dishes.
The medical form of ginger historically was called Jamaica ginger; it was classified as a stimulant used to aid digestion. In the West, powdered dried ginger root is made into capsules and sold in pharmacies for medicinal use.
Essential oils are commonly defined by the fact that they convey characteristic fragrances. Essential oils are generally extracted by distillation. They are used in perfumes, cosmetics, soaps and other products, for flavoring food and drink, and for adding scents to incense and household cleaning products. Interest in essential oils has revived in recent decades with the popularity of aromatherapy, a branch of alternative medicine that claims that essential oils and other aromatic compounds have curative effects. Oils are volatilized or diluted in a carrier oil and used in massage, diffused in the air by a nebulizer, heated over a candle flame, or burned as incense.
The techniques and methods used to produce essential oils was first mentioned by Ibn al-Baitar (1188–1248), an Andalusian physician, pharmacist and chemist.
