Prunes vs Aloo Bukhara for Constipation (Qabz): Which Helps?
If you want a dried plum for qabz, pick prunes: the big, soft, sweet, nearly black ones. Are prunes good for constipation? Yes, and the reason is simple enough to explain to a child. The small, sour aloo bukhara that goes into biryani is a different plum, eaten in amounts far too small to move anything. Here’s how to tell them apart at the shop, how many prunes to eat, what prune juice does and doesn’t do, portions for children by age, and the signs that mean it’s time for a doctor rather than a fruit bowl.

Prunes and aloo bukhara are not the same thing
Both are dried plums, which is where the mix-up starts. In Pakistan and north India “aloo bukhara” is used for the fresh summer plum and for the small dried sour plum sold for cooking, while “prunes” means a specific sweet plum dried whole until it turns soft, sticky and almost black. The names get swapped all the time, even on shop labels.
| Prunes | Dried aloo bukhara | |
|---|---|---|
| Size | Thumb-sized, plump | Small, like a large grape |
| Colour | Deep black-brown, glossy | Golden-brown to dark red-brown |
| Feel | Soft, squashy, sticky | Firm, leathery |
| Taste | Sweet, like jam | Sour and tangy |
| Main use | Snack, breakfast, qabz | Biryani, qorma, chutney |
Taste settles it. A prune is sweet enough to eat like a toffee. Nobody snacks on a handful of sour aloo bukhara, and that’s exactly the point: you’d need a lot of them for any effect on the bowel, and the three or four in a pot of biryani are there for flavour. For cooking with them, see our aloo bukhara guide for biryani and chutney.
Two things most people don’t know. Prunes come from plum varieties so sweet that they dry whole, stone and all, without fermenting on the tray, which ordinary plums can’t do. And in 2000, American growers started labelling prunes “dried plums” because the old name had an image problem, and plenty of packs still say it.
Myth: aloo bukhara in the biryani will sort out qabz
Truth: a few sour plums spread across a whole pot give each plate a trace. People believe it because the whole plum family has a loosening reputation, and that part is fair. Fresh, ripe summer aloo bukhara eaten with the skin, two or three at a time, does help some people. The dried cooking kind, in cooking amounts, doesn’t.
Why prunes help constipation, explained simply
Prunes work in three small ways at once. First, fibre: the skin and flesh act like a sponge, soaking up water and making stool bigger and softer, which gives the gut something to push. Second, sorbitol, a natural sugar alcohol that your gut absorbs only slowly, so much of it stays in the bowel and pulls water in with it, the same reason sugar-free sweets carry a warning about loose motions. Third, natural plant compounds in prunes seem to nudge the bowel along too, though that part is less well understood.
Put together, prunes are one of the few foods with a reputation for qabz that holds up well. They’re gentler than a laxative. They’re also slower.
Fibre makes the sponge, sorbitol brings the water, and you have to drink enough for either to do its job.
What about prune juice?
Prune juice keeps the sorbitol but loses most of the fibre, so it can still help, especially for people who find whole prunes hard to eat. It’s also more sugar in a quick gulp and less filling. Whole prunes win for most adults. If you prefer juice, start with half a glass (about 120 ml) of 100% prune juice with no added sugar in the morning, and see how you respond before having more.
Prunes aren’t a stand-in for the basics. Water, daily walking, enough fibre across the day and a regular toilet time all matter just as much; our qabz home remedies guide covers that routine, and how to take isabgol safely is the next step if food alone isn’t enough.
How many prunes to eat for constipation, and how
A common adult starting amount is 4 to 6 prunes a day, about 50 g. Too many on day one gives you gas, cramps and a sudden rush to the bathroom, so build up.
- Day 1 to 3: eat 3 prunes in the morning with a full glass (250 ml) of water.
- Day 4 onwards: if nothing has changed, go up to 5 or 6 a day, split between breakfast and the evening.
- Drink more water. Aim for an extra 2 glasses across the day. Without water, extra fibre can make things harder, not softer.
- Soak them if they’re hard. Cover with warm water for 15 minutes, or overnight in the fridge, and drink the soaking water too.
- Give it time. Some people notice a change the next day; for others it takes a few days of steady eating.
- Back off if stools turn loose. Drop to 2 or 3 a day. The right amount is the one that keeps you comfortable.
Stewed prunes for the week
Put 12 prunes, 400 ml of water and a small stick of darchini (cinnamon) in a pan. Simmer for 10 minutes until plump and the liquid turns syrupy. Cool and refrigerate for up to 3 days. Each morning, eat 4 prunes with a few spoons of the liquid, on their own or over a katori of plain dahi with a spoon of oats.
In many desi homes the summer fix was a sharbat of dried aloo bukhara soaked overnight, mashed and strained, drunk for heat and thirst and as a mild loosener. Unani writing counts aloo bukhara among the cooling fruits, suited to hot weather. It’s a pleasant, sour drink and part of a real tradition, but it’s weaker for qabz than a few sweet prunes. Many families now soak prunes the same way, which is a sensible update.
Prunes for babies and children: portions by age
Prunes are a gentle first choice for a constipated child on solids. Sticky pieces can be a choking risk, so chop or mash them for children under 5, and never add sugar or honey for a baby under 1.
| Age | How much | How to give it |
|---|---|---|
| Under 6 months | None | Breast milk or formula only; see the doctor for hard stools |
| 6 to 12 months | 1 to 2 tablespoons | Smooth puree or soaking water, once a day |
| 1 to 3 years | 1 to 2 prunes | Mashed or chopped small, stirred into dalia or dahi |
| 4 to 8 years | 2 to 3 prunes | Chopped, with a glass of water |
To make baby puree, soak 6 pitted prunes in 100 ml of hot water for 15 minutes, blend with the water until smooth and freeze in an ice cube tray; one cube thawed is about 2 tablespoons. Some doctors suggest a little diluted prune juice for a toddler, and it’s worth asking your child’s doctor how much rather than guessing. The full age-by-age plan is in our child constipation guide.
Diabetes, kidneys and who should limit prunes
Prunes are sweet, but they don’t hit blood sugar as hard as their taste suggests, because the fibre and sorbitol slow things down. They’re still concentrated fruit. For people with diabetes, about 3 prunes is roughly one fruit portion, similar to a small apple; eat them with a meal, dahi or a few nuts rather than on an empty stomach, and skip prune juice, which is a quick sugar hit. Count them in your day, and keep your medicines exactly as your doctor set them.
- Kidney disease: prunes are high in potassium. Ask your kidney doctor or dietitian before eating them daily.
- Blood thinner warfarin: prunes carry some vitamin K. Keep the amount you eat steady from week to week and tell your doctor about big changes.
- IBS: sorbitol is a common trigger for gas and bloating, so start with one or two.
- Weight watchers: each prune is about 20 to 25 calories; six is a small snack’s worth.
Prunes are for everyday, ordinary qabz. See a doctor promptly for blood in the stool or black, tarry stools, weight loss you can’t explain, severe tummy pain or swelling with vomiting, being unable to pass wind, or a new change in bowel habit that lasts more than 3 weeks, especially after 50. In pregnancy, prunes are a safe food choice, and it’s wise to mention constipation at your check-up since iron tablets often cause it. For a baby, go straight to the doctor for blood in the nappy, a swollen hard tummy, vomiting or poor feeding, and for any constipation under 6 months. If you’re on medicines that raise potassium, or on warfarin, have a quick word with your doctor before starting a daily prune habit.
Prune questions, answered
Are prunes good for constipation?
Yes. Their fibre bulks and softens stool, and their natural sorbitol pulls water into the bowel. Most adults do well starting with 3 prunes a day and building to 4 to 6, with extra water.
How fast do prunes work for constipation?
Often within a day or two, but it varies. Some people need several days of eating them steadily. If nothing has changed after a week of prunes, water and walking, look at the rest of your diet and routine, or ask a doctor.
Is prune juice good for constipation?
It can help, because it keeps the sorbitol even though most of the fibre is gone. Start with half a glass of unsweetened juice. Whole prunes are usually the better choice since they fill you up and bring fibre too.
Is aloo bukhara the same as prunes?
Not quite. Both are dried plums, but prunes come from a sweet variety dried until soft and black, while dried aloo bukhara is a smaller, sour cooking plum. In daily speech the names overlap, so check the taste and texture.
Can diabetics eat prunes?
Yes, in small portions. About 3 prunes counts as one fruit serving; eat them with a meal or with dahi or nuts, and avoid prune juice. Check your sugar readings the first few times to see how your body responds.
Can I eat prunes at night?
You can. Some people prefer an evening portion so things move in the morning. If they cause gas or cramps overnight, move them to breakfast instead.
Are prunes good for babies?
From 6 months, a tablespoon or two of smooth prune puree or soaking water once a day is a common, gentle option for hard stools. No sugar, no honey, and no prunes at all under 6 months; see the doctor instead.
Can I eat prunes during pregnancy?
Yes, prunes are a good food for pregnancy constipation, alongside water and gentle walking. Start with a few a day. If constipation is bad or started with iron tablets, bring it up with your doctor or midwife.
What are the side effects of eating too many prunes?
Gas, bloating, cramps and loose motions are the usual ones, because of the sorbitol and fibre. Cut back to 2 or 3 a day and they settle. The sugar and calories add up too if you eat them by the handful.
Are prunes good for iron deficiency?
They contain a little iron, but not enough to fix a deficiency. If you’ve been told you’re low in iron, follow the plan your doctor gives you and get iron from foods like meat, daal, chana and leafy greens alongside it.
How do I store prunes after opening?
In an airtight jar or zip bag, ideally in the fridge, where they keep soft for several months. A dusty white coating is usually sugar coming to the surface, not mould. Fuzzy spots or a sour, fermented smell mean throw them out.
How do I choose good prunes?
Look for plump, glossy, soft prunes that give when pressed, and check that the ingredient list says prunes and not added sugar or syrup. Rock-hard ones are old but can be soaked. Pitted is easier, but still check for stone bits before giving them to a child.
Are prunes good for weight loss?
Only as a swap. Two or three prunes are a filling, sweet alternative to biscuits, but they aren’t low in calories and won’t burn fat on their own. For weight loss, portion is everything.
