Draksha is the Ayurvedic name for the grape, and above all for the dried grape — the raisin. It is a single drug in Ayurveda. That means one plant used on its own, not a mix of herbs.
Ayurveda gives it for a dry cough, a dry sore throat, thirst, low energy, and hard stools that are hard to pass. In Ayurvedic terms it is sweet and cooling. It is also the base of a sweet fermented tonic called Draksharishta, which makes its own alcohol while it brews.
The proof is thin. Draksha has a long and deep place in Ayurveda, but we could not find human trials that test it for these uses. A long history of use is not proof that a thing works, and that applies to everything on this page.
No one has shown exactly how Draksha works. What follows is a fair guess from what raisins contain, not a proven chain of events.
Raisins hold fibre and natural sugars. Both pull water into the gut, which can make stool softer and easier to pass. Soaking the raisins in water first may add to this effect.
For a dry cough and a scratchy throat, the reason may be simple. Sweet, sticky fruit coats the throat and makes you swallow more often. That feels soothing, but it does not treat the cause of the cough.
Raisins are also a quick source of sugar and some iron. That may be why Ayurveda gives them to people who are weak or getting over an illness. Feeling stronger after eating food that is easy to digest is not the same as a drug effect.
Raisins carry polyphenols (plant chemicals that act as antioxidants). In test tubes these can mop up harmful particles. Whether that changes anything in a person who eats a handful of raisins is not known.
Draksha is sold as food and as Ayurvedic medicine. Common forms are:
- whole dried raisins, eaten as they are - raisins soaked in water overnight, the most common Ayurvedic way to take them - raisin water, made by straining the soaking water - Draksharishta, a sweet fermented liquid that holds alcohol made during brewing - Drakshadi kwatha, a water decoction (a drink made by boiling the fruit) - fresh grapes and grape juice
The fermented tonic is the form with the most safety strings attached, because of its alcohol.
Draksha appears in the oldest Ayurvedic texts, including the Charaka Samhita and the Sushruta Samhita, written roughly two thousand years ago. It is listed there for thirst, cough, fever, weakness and dry stools.
It is a staple rather than a rarity. Grapes and raisins also had a long medical life outside India, in Unani and in Greek humoral medicine, though this page describes the Ayurvedic use.
See a doctor if constipation lasts more than two weeks, or if you cannot pass stool or wind at all. Get urgent help for blood in your stool, black tarry stool, or bad stomach pain.
Book an appointment for a cough that lasts more than three weeks, a cough with blood, weight loss you cannot explain, or thirst and tiredness that keep getting worse. If you have diabetes and your readings climb after you start Draksha, stop it and speak to your diabetes team.
Get medical help straight away for swelling of the lips or tongue, a rash with breathing trouble, or a fast or uneven heartbeat.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Draksha 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.
