What is Draksha?

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.

How does Draksha work?

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.

What forms does Draksha come in?

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.

Where it comes from:

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.

What does Draksha help with?

• Constipation (hard stools that are hard to pass): This is the most common modern use, and the one with the clearest reason behind it. Raisins bring fibre, sugar and water into the gut, which can soften stool. Eating dried fruit is a standard, gentle thing to try for mild, short-lived constipation. We found no trial of Draksha itself as an Ayurvedic remedy. Treat it as food that may help, not as a laxative you can rely on.
• Dry cough and dry sore throat: Ayurveda has used soaked raisins and Draksharishta for a dry, tickly cough for centuries. The likely effect is simple soothing of the throat. There is no trial evidence that it shortens a cough or clears an infection. A cough that lasts more than three weeks needs a doctor, not more raisins.
• Thirst and dry mouth: Classical texts list Draksha for thirst, and soaked raisins with their water are a common home answer to a dry mouth. This is comfort care. Ongoing thirst can be a sign of diabetes or another problem, so get it checked rather than treated at home.
• Low energy during recovery from illness: Ayurveda uses Draksha as a building food for people who are weak after fever or illness. It is easy to digest and gives quick sugar. That is a food effect, not a drug effect, and it has not been tested in trials. It does not replace treatment for whatever caused the weakness.
• Low iron intake in the diet: Raisins contain a little iron, and Ayurveda links Draksha with strength and good colour. The amount is small. Raisins cannot correct true iron-deficiency anaemia (low iron in the blood). If you are tired and pale, ask for a blood test instead of guessing.
• Acidity and burning in the stomach (traditional use): Draksha is called cooling in Ayurveda and is given for burning in the stomach and chest. We found no human trial supporting this. Some people find sweet, acidic dried fruit makes reflux worse, so stop if burning increases.

Which foods are rich in Draksha?

1. Raisins, sultanas and currants: these are Draksha itself, in dried form
2. Munakka, the large seeded raisin used in Ayurveda and Unani
3. Fresh grapes: the same fruit, with more water and less sugar per bite
4. Grape juice: sweeter and lower in fibre than the whole fruit
5. Draksharishta: the fermented Ayurvedic tonic made from grapes

Practical Tips:

The grapefruit warnings you see on medicine labels do not apply to grapes or raisins; they are different fruits. One separate fact worth knowing: grapes and raisins can cause kidney failure in dogs, so keep them away from pets.

What are the side effects of Draksha?

• Loose stools or diarrhoea if you eat a lot
• Gas, bloating and stomach cramps
• A rise in blood sugar, because raisins are concentrated sugar
• Weight gain with large daily amounts
• Tooth decay, as raisins stick to teeth
• Wheezing or a stuffy nose in people sensitive to sulphites (a preservative on dried fruit)
• Allergic reaction in people allergic to grapes, with itching, rash or swelling
• Drowsiness or a flushed face from the alcohol in Draksharishta

Good to know:

For most people raisins are a food and cause nothing worse than gas or loose stools. Problems come from amount, from sugar, and from the alcohol in the fermented tonic.

The two groups who need to think first are people with diabetes and people with advanced kidney disease. Serious reactions are rare and are usually allergy.

How much Draksha should you take?

• Recommended daily: No tested dose exists. The amounts below come from traditional practice and everyday food use, not from trials. Soaked raisins: about 10 to 30 g a day, which is roughly 15 to 30 raisins. Soak them in a cup of water overnight and drink the water too. Draksharishta: about 12 to 24 ml, usually mixed with the same amount of water, once or twice a day. This form contains alcohol. Start at the low end. More raisins mostly means more sugar and looser stools, not more benefit.
• Best time of day: Soaked raisins are usually taken in the morning on an empty stomach, with the soaking water. For a dry throat at night, a few raisins in the evening are also traditional. Draksharishta is normally taken after meals.
• With or without food: Soaked raisins are taken on an empty stomach in the morning. Draksharishta is taken after food. If plain raisins upset your stomach, eat them with a meal instead.
• Time to effect: For stools, expect any change within one to three days. Throat soothing is immediate but short. Any change in energy takes weeks, if it comes at all.
• How long to take it: As a food, daily use is fine for most people. As a remedy, give it about two weeks and then judge. If your constipation, cough or tiredness has not shifted in two weeks, stop and see a doctor. Long courses of Draksharishta should be run past a qualified practitioner because of the alcohol and sugar.
