Homemade Electrolyte Drink: ORS vs Nimbu Pani vs Coconut Water
Only one of these three drinks is a real electrolyte drink for loose motions, vomiting or heat exhaustion, and it’s the one you make with a measuring spoon: 1 litre of clean water, 6 level teaspoons of sugar, half a level teaspoon of salt. Nimbu pani is a pleasant drink with almost no salt in it. Coconut water is a good potassium drink with even less. This guide gives you the exact house recipe, the honest numbers for all three, and the four situations where nothing but ORS will do.
In brief
- House ORS: 1 L water, 6 level tsp sugar, half level tsp salt. Nothing else.
- Nimbu pani: water, lemon, sugar and a pinch of salt. Refreshing, not rehydrating in illness.
- Coconut water: plenty of potassium, very little sodium. Fine for a hot afternoon, wrong for diarrhoea.
- Keep the mix: 24 hours at room temperature, then throw it out and make fresh.

What an electrolyte drink actually has to do
When you have loose motions, the gut leaks water and salt (sodium) faster than plain water can replace them. Drinking water alone can even make things worse in a bad bout, because it dilutes what little salt is left. An oral rehydration solution fixes this with a trick the body already knows: a small amount of glucose sitting next to a small amount of sodium makes the small intestine pull both in together, and water follows. Too much sugar breaks the trick and pulls water the other way, back into the gut. That’s why a fizzy drink or a sweet sharbat can make loose motions looser.
The house ORS recipe, measured
This is the recipe every post on this site uses, and it matches the WHO home mix. We keep it identical on purpose so nobody has to remember two versions. The full method, with sachets, storage and amounts by age, lives in the homemade ORS (namak cheeni ghol) post; here is the formula itself.
- Boil 1 litre of water and let it cool until it’s comfortably warm or fully cool. If the tap water is trusted, filtered water is fine.
- Add 6 level teaspoons of ordinary sugar (about 25 g). Level means scraped flat with a knife, not heaped.
- Add half a level teaspoon of table salt (about 2.5 g). Use a real teaspoon measure, not a chai spoon from the drawer, which can be half the size.
- Stir until nothing sits at the bottom. Taste it. It should taste like tears, faintly salty and faintly sweet. If it tastes clearly salty, pour it away and start again with less salt; too much salt is the one mistake that can hurt.
- Give it in small sips, a tablespoon or two every few minutes, rather than a glass in one go. A glass gulped down often comes straight back up.
- Cover it. After 24 hours, throw the rest out and mix fresh.
A pharmacy sachet is better than the home mix when you can get one, because the factory has weighed the salt and added a little potassium and citrate.
Why nimbu pani is not ORS
A glass of nimbu pani is water, the juice of half a lemon, 2 or 3 teaspoons of sugar and, if you’re lucky, a pinch of salt. Look at those amounts against the recipe above. The sugar in one glass of nimbu pani is often the same as the sugar in a whole litre of ORS. The salt is a pinch, perhaps a tenth of a teaspoon, where ORS puts half a teaspoon in a litre. Scale a glass of nimbu pani up to a litre and you get four times the sugar and roughly the same salt as a proper mix, which is exactly the wrong way round.
None of this makes nimbu pani bad. On a hot day when you’ve been sweating and you’re eating normal salted food, it’s a lovely drink. Just don’t reach for it when someone is running to the toilet every hour.
Can you turn nimbu pani into ORS?
Yes, and it’s a useful trick for someone who refuses plain ORS. Make the house ORS exactly as above, then squeeze a quarter of a lemon into the litre. That’s flavour only; the ratios stay right. What you can’t do is start with sweet nimbu pani and add salt, because the sugar is already far too high.
Coconut water: the honest numbers
Coconut water gets sold as “nature’s ORS”, and the numbers don’t support that. A 250 ml glass of fresh nariyal pani has roughly 600 mg of potassium, which is a lot, about the same as a large banana. Its sodium, the salt you actually lose in diarrhoea, is only around 60 mg in that glass, about a twentieth of a teaspoon of salt. A litre of house ORS carries around 1,000 mg of sodium. So coconut water gives you the electrolyte you’re losing least of, in abundance, and the one you’re losing most of, hardly at all.
That makes it a good drink for a hot afternoon, after moderate sweating, or for someone convalescing who is eating salted khichdi and simply wants something cool. It’s the wrong drink as the only fluid during heavy loose motions, and it’s actively risky for anyone with kidney disease or on potassium-sparing blood pressure tablets, because that potassium load can’t be cleared. The coconut water guide goes through choosing a nariyal and the kidney warning in full.
The three drinks side by side
| Per 250 ml glass | House ORS | Sweet nimbu pani | Coconut water |
|---|---|---|---|
| Sodium | About 250 mg | Pinch, under 100 mg | About 60 mg |
| Sugar | About 6 g | 10 to 15 g | About 6 g |
| Potassium | Low (sachets add some) | Low | About 600 mg |
| Best for | Loose motions, vomiting, heat exhaustion | Thirst on a normal day | Hot weather, convalescence |
When only ORS will do
Four situations. Treat these as rules, not preferences.
Loose motions, three or more watery stools in a day. Every stool loses salt. Sip ORS after each one, a cup for an adult, and keep eating. The adult loose motions guide gives amounts and the red flags.
Vomiting with any diarrhoea. Tiny sips, a teaspoon every minute or two if that’s all that stays down. Nimbu pani and coconut water both come back up more easily.
Heat exhaustion. Heavy sweating, cramps, headache, cool clammy skin. Sweat is salty; replace it with ORS in the shade, half a litre over half an hour. Hot dry skin with confusion is heatstroke, and that’s an ambulance, not a drink.
A child or an elder who is drinking less than they’re losing. Children and old people dehydrate fast and quietly. Babies keep breast milk or formula as the main fluid and take ORS by spoon between feeds; the amounts by age are in the children’s loose motions post.
An adult or child can’t keep even sips down for 6 hours, has passed no urine in 8 hours (6 in a young child), is drowsy, floppy or confused, has blood in the stool, a fever of 39 °C or above with the loose motions, or sunken eyes and a dry mouth that a few cups of ORS haven’t improved within 4 hours. Anyone with kidney disease, heart failure or on a diuretic should ask their doctor how much fluid and salt they may take before a bout, not during one; ORS is high in salt and coconut water is high in potassium, and both can matter for them. In pregnancy, loose motions lasting over 24 hours need a doctor the same day. Never make ORS stronger “to work faster”. Too much salt in a small child is dangerous.
Myth: sweet drinks and juice count as electrolytes
Cola, energy drinks, packet juice and glucose powder in water are all sugar first, salt nowhere. They pull water into the gut and can make loose motions worse. “Glucose-D” style powders help a tired person feel less faint but do nothing for salt loss. Sports drinks are closer, but most still carry far more sugar and far less salt than ORS.
Electrolyte drink questions people actually ask
Kya nimbu pani ORS ki jagah le sakta hai? Can nimbu pani replace ORS?
No. Nimbu pani has far too much sugar and almost no salt for diarrhoea or vomiting. It’s a fine drink for ordinary thirst. For illness, make the house ORS and, if you like, add a squeeze of lemon for taste.
Is coconut water better than ORS for loose motions?
No. Coconut water has plenty of potassium but only a fraction of the sodium you lose in loose motions, and sodium is what matters most. Use it as an extra drink once you’re eating again, not as the main fluid during the bout.
What is the exact homemade ORS recipe?
One litre of clean water, six level teaspoons of sugar and half a level teaspoon of salt, stirred until clear. Use proper measuring spoons and level them. Throw it out after 24 hours.
Can I use gur or honey instead of sugar in ORS?
Gur works if you weigh it, about 25 g per litre, since it’s mostly sugar. Honey is harder to measure and must never be used for a baby under 1 year. Plain sugar is simplest and safest.
Can I give ORS to a baby under 6 months?
Only on a doctor’s advice. Under 6 months, breast milk or formula stays the main fluid, offered more often. A doctor may add ORS by spoon for diarrhoea. Never give plain water, nimbu pani or coconut water to a baby this young.
Can people with high blood pressure or kidney disease drink ORS?
Ask the doctor first, ideally before you fall ill. ORS is salty, coconut water is high in potassium, and both can be a problem with kidney disease, heart failure or certain BP tablets. Short use in a real bout is usually accepted, but the doctor sets the limit.
Is ORS safe in pregnancy?
Yes, the standard mix is safe in pregnancy and is the right drink for loose motions or vomiting. Loose motions past 24 hours, or any blood, need a doctor the same day.
How long does mixed ORS keep?
Twenty-four hours, covered, whether on the counter or in the fridge. After that, germs grow in the sugar water, so mix a fresh litre.
Most home dehydration comes down to one measuring spoon used honestly. Keep the ratio on a card inside the kitchen cupboard, keep a couple of sachets in the Desi Remedies shelf, and save the nimbu pani and nariyal pani for the days you’re well enough to enjoy them.
