Kebuka is the root stem of a tall garden plant. Its Latin name is Cheilocostus speciosus. Most people know it as crepe ginger.
In Ayurveda the root is dried, ground and used on its own. That is why it is called a single drug. Old texts point it at fever, coughs, skin rashes and gut worms.
The human proof is very thin. Almost all we know comes from lab dishes and animal tests. Long use in a tradition is not the same as proof that it works.
No one has shown how Kebuka acts in the human body.
The root holds diosgenin, a plant steroid. Drug makers use this same plant matter as a raw stock to build some lab-made hormones. Lab and animal tests hint at small effects on blood sugar and on swelling.
Ayurveda gives its own reason. Old texts call the root sharp and warm, and say it dries damp and clears the gut and chest. That is a way of thinking inside one tradition, not a tested cause.
Dried root powder, called churna, is the most common form. Shops sell it loose or in capsules.
A water brew, called a decoction, is also used. You simmer chopped dry root in water and then strain it.
The root also turns up inside mixed Ayurvedic formulas. Some folk healers press fresh root for juice or spread it on the skin as a paste. In parts of India and Southeast Asia the young shoots are eaten as a sour vegetable.
Crepe ginger grows wild across South and Southeast Asia. Ayurvedic texts name the root Kebuka and place it with drugs for fever, worms and skin trouble.
Village healers in India, Sri Lanka and Indonesia used it in much the same way. It has stayed a single-plant drug rather than the star of a famous blend.
See a doctor if you keep vomiting, cannot hold down fluids, or have loose stools for more than a day. Get help the same day if you feel shaky, sweaty and confused, as that can mean low blood sugar. Go to an emergency department if you are pregnant and start to bleed or cramp. Also see a doctor if a fever lasts more than three days, if a rash spreads or weeps, or if you think you have worms.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Kebuka is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
