Kadha Premix Powder: What One Cup Has, and Where to Stop
Verdict: a kadha premix powder is a handy shortcut for a warm, spicy drink that soothes a scratchy throat. Half a teaspoon per cup holds only a pinch of each spice, so it’s comfort in a cup, not protection from illness.
Before you start
- The premix: 20 g sonth, 20 g dalchini, 10 g kali mirch, 10 g laung and 20 g dried tulsi powder (an 80 g jar).
- Per cup: half a level teaspoon, about 1.5 g of powder.
- Nutrition: about 5 kcal. Everything else is a trace.
- Sensible use: one cup, 3 to 4 days a week, or daily for a week when your throat is sore.

Since 2020 the jar has lived next to the chai patti in many kitchens: “bas aadha chamach, ubaal lo, bimari door.” The first part is fine. The second part isn’t something a spoon of spices can promise. Here’s what half a teaspoon really holds, how to brew it using the same method as our house kadha recipe, and where to stop. It belongs to our Desi Remedies series.
What one cup of kadha premix actually has
Split the half teaspoon by each spice’s share of the 80 g jar. Sonth, dalchini and tulsi are each 20 of 80, a quarter, so each gives about 0.4 g per cup, while kali mirch and laung are each 10 of 80, an eighth, so each gives about 0.2 g.
| Spice | Per cup (approx.) | Roughly like |
|---|---|---|
| Sonth (dry ginger) | 0.4 g | a thin slice of fresh adrak |
| Dalchini | 0.4 g | a fingernail-sized bit of stick |
| Tulsi powder | 0.4 g | a small handful of fresh leaves, dried down |
| Kali mirch | 0.2 g | 4 to 5 peppercorns |
| Laung | 0.2 g | about 2 cloves |
Nutrition per cup is tiny: about 5 kcal, a fraction of a gram of fibre, and trace minerals nobody should count. What you do get is heat, aroma and the throat-warming bite of gingerols from the sonth and piperine from the pepper, and warm liquid, steam and that bite together are why a cup feels good when you’re coughing.
The kadha soothes. It doesn’t stand guard.
What each spice is doing
- Sonth: the warmth and some settling of a queasy stomach. Dry ginger is sharper than fresh; see our adrak and sonth guide.
- Dalchini: sweetness without sugar. Most shop dalchini in Pakistan and India is cassia, which carries coumarin; more on that below.
- Kali mirch: the bite at the back of the throat. Too much brings acidity.
- Laung: a numbing, clove-oil warmth. Strong, so it stays small.
- Tulsi: herbal aroma. Dried powder loses much of the fresh leaf’s scent, so store it well.
How to brew it, the house kadha way
- Put 2 cups (about 400 ml) of water in a small pan and bring it to a boil.
- Add half a level teaspoon of premix, enough for the one cup this makes. Stir so it doesn’t clump.
- Lower the heat and simmer for 8 to 10 minutes, until it reduces to about 1 to 1.5 cups.
- Strain through a fine tea strainer lined with a thin muslin cloth; powder leaves grit.
- Let it cool to warm. Add honey or gur to taste only now if you like, and never give honey in any form to a baby under 1 year.
- Drink one cup. Don’t sip it all day.
Making the premix at home
- Dry-roast 20 g dalchini, 10 g kali mirch and 10 g laung together on low heat for 1 to 2 minutes, just until fragrant. Laung burns fast.
- Spread on a plate and cool fully, about 15 minutes.
- Grind them fine, then pulse in 20 g sonth powder and 20 g dried tulsi powder.
- Sieve, and regrind the coarse bits once.
- Store in a small dry glass jar away from the stove and use it within about 4 to 6 weeks, because ground spices fade fast, and if it smells flat, dusty or musty, or you see clumps or specks of mould, throw it out.
What kadha can’t do
It can’t stop you catching a cold or flu, it can’t shorten a real infection much, and it can’t stand in for vaccines, handwashing, rest and fluids. There’s no amount of any kitchen spice that makes your defences measurably stronger, and drinking more doesn’t add protection; it adds acidity; what it can do is ease a scratchy throat, warm you up and give you a reason to drink fluids. That’s worth having.
What if you change the amounts?
- More dalchini: sweeter, but more coumarin if it’s cassia. Cassia coumarin can strain the liver when a lot is taken every day, so keep dalchini at a quarter of the jar or less, or use Ceylon (true) cinnamon if you drink kadha often.
- More kali mirch or laung: more burn, more heartburn and no extra comfort.
- More sonth: more heat. Good on a cold day, rough on an acidic stomach.
- More tulsi: fine for taste; don’t turn it into a herbal medicine.
- A heaped spoon instead of half: twice the spice and twice the acidity, for no benefit.
- Adding giloy or mulethi: leave them out. Giloy has been linked to liver injury (see our giloy liver warning), and mulethi raises blood pressure.
An optional gentler version
For acidity-prone stomachs, try 25 g sonth, 20 g Ceylon dalchini, 5 g kali mirch, 5 g laung and 25 g tulsi. Same half teaspoon per cup, noticeably softer on the chest.
Blood thinners: dalchini, laung and sonth add slightly to the effect of warfarin and similar medicines. Keep kadha occasional and tell your doctor. Diabetes medicines: cinnamon may add a little to sugar-lowering; check your readings. Never start or stop a medicine because of kadha. Pregnancy: an occasional weak cup is a food amount, but skip daily kadha and heavy tulsi, and ask your doctor. Acidity or ulcers: pepper, laung and sonth can burn; halve the powder or skip it. Liver disease: avoid cassia-heavy premixes. Children: nothing but milk under 6 months, no kadha under 1, and for older children a very weak cup, no honey under 1, only after asking your doctor.
See a doctor if a sore throat lasts more than a week, a fever passes 39 °C or lasts more than 3 days, swallowing becomes very painful or you drool, you can’t open your mouth fully, or breathing gets hard. Those need an examination, not another cup.
Cheaper swaps that work as well
A cup of adrak chai with a couple of peppercorns does almost the same job. Warm salt water gargles (half a teaspoon of salt in a glass of warm water) ease a sore throat well, while warm water with lemon and a spoon of honey (adults and children over 1) soothes a cough. Plenty of fluids and sleep do more than any spice.
Questions about kadha powder
How much kadha powder per cup?
Half a level teaspoon, about 1.5 g, simmered in water for 8 to 10 minutes. A heaped spoon only adds heat and acidity.
Can I drink kadha every day?
For a week during a cold, most healthy adults are fine with one cup a day, while long term 3 to 4 cups a week is plenty.
Does kadha prevent Covid or flu?
No. It can soothe a sore throat, but it doesn’t stop infection; vaccines, handwashing and staying home when ill do that work.
Can I just stir the powder into hot water?
You can, but it tastes raw and gritty. Simmering for a few minutes and straining gives a smoother, better-flavoured drink.
Is kadha safe in pregnancy?
An occasional weak cup is usually fine as food, but avoid daily strong kadha, extra tulsi and added herbs, and check with your doctor.
Can children drink kadha?
Not under 1 year. For older children, a very weak cup now and then is a question for your doctor, and honey never goes to a baby under 1.
Is kadha safe with blood thinners?
Occasionally, yes, but dalchini, laung and ginger add slightly to their effect, so tell your doctor if you drink it regularly.
Why does kadha give me acidity?
Pepper, laung and sonth irritate an acidic stomach. Use less powder, drink it after food, and leave out the pepper.
Which cinnamon is better for kadha?
Ceylon cinnamon, the thin papery quills, carries much less coumarin than cassia, so if you drink kadha often it’s the safer pick.
How long does kadha premix last?
About 4 to 6 weeks in a dry, airtight jar, and once it smells flat, the flavour and the warmth have gone.
