Crepe Ginger
Costus speciosus
Long before it found its way into ornamental gardens for its spiraling stems and crepe-paper blossoms, Costus speciosus was a workhorse of the village healer's kit across India and Southeast Asia. Ayurvedic and folk traditions turned to the pounded rhizome for coughs, fevers, and troubled digestion, and it earned a place alongside ginger and turmeric in household remedy cabinets. Temple gardens have grown it for generations as much for its beauty as its usefulness, and its Sanskrit name, kebuka, still echoes through old medical texts. Modern researchers have taken a particular interest in the rhizome's saponin content, which resembles compounds found in wild yam.

Traditional preparations.
A gently simmered decoction is the traditional way this rhizome has been prepared, historically used to help ease a nagging cough or the discomfort of a fever.
Traditionally, a decoction is made by simmering 1/2 teaspoon of dried, sliced rhizome in 1 cup of water for 10 to 15 minutes, then straining before drinking.
Safety.
The rhizome contains steroidal saponins linked to effects on uterine activity, so avoid during pregnancy and breastfeeding. Eating the raw rhizome or large amounts of any preparation can upset the stomach.
