There is a smell that most Indian homes know well in winter — ginger and tulsi simmering in a steel pan, with a little black pepper and cinnamon in the air. That is kadha. If you want a simple immunity kadha recipe you can make in 15 minutes with things already in your kitchen, this guide is for you. You will get the classic recipe, three useful variations, the best time to drink it, how much is enough, and who should be careful with it.
What is an immunity kadha recipe?
Kadha, also spelled kadha or kashayam, is a decoction. That simply means you boil plant material in water until some of the water evaporates and the flavour and plant compounds move into the liquid. In Ayurveda, kadha has been used for centuries for fever, cold, cough, and low digestion.
The classic immunity kadha uses giloy as the base, with tulsi, ginger, black pepper, cinnamon, and sometimes cloves and cardamom. If you want the full story on giloy itself — its benefits, forms, and who should avoid it — read our Giloy Benefits for Immunity: How to Use, Kadha Recipe & Side Effects (Round 2 article). Each ingredient has a role. Giloy is the main herb for immune support. Tulsi is calming and supports the airways. Ginger warms the body and helps with nausea and a blocked nose. Black pepper helps the body use the other ingredients better. Cinnamon adds warmth and flavour. Honey, added after the kadha cools a little, soothes the throat.
Fresh ingredients from your kitchen give you a better-tasting drink, and you know exactly what went into it.
Immunity kadha recipe: the classic version (makes 2 cups)
This is the recipe most families use. It takes about 15 minutes from start to finish.
Ingredients:
- 1 piece of fresh giloy stem, about 4 to 6 inches long (roughly 10 g), washed and cut into small pieces
- 8 to 10 fresh tulsi leaves, washed
- 1 inch piece of fresh ginger, crushed
- 4 to 5 black peppercorns, lightly crushed
- 1 small stick of cinnamon (about 1 inch)
- 2 cloves (optional)
- 2 cups of water
- Half a teaspoon of honey per cup (optional, add after cooling a little)
- A few drops of lemon juice (optional)
Method:
- Put 2 cups of water in a steel pan. Add the giloy pieces, tulsi, ginger, peppercorns, cinnamon, and cloves.
- Bring it to a boil on medium heat, then turn the flame low.
- Let it simmer until the water reduces to about 1 cup. This takes 10 to 12 minutes. The colour will turn a light golden brown.
- Switch off the flame and strain the kadha into cups through a fine strainer.
- Let it cool for 2 to 3 minutes, then stir in honey if you like.
- Drink it warm, not hot enough to burn your mouth.
How much to drink: Half a cup in the morning and half a cup in the evening is a good amount for a healthy adult. Or one small cup once a day, usually in the morning. Drink it for 1 to 2 weeks when you are recovering from a cold or during a change of season, then take a break. Do not drink 3 or 4 cups a day — kadha is strong, and more will irritate your stomach.
Immunity kadha recipe variations for different needs
Once you know the classic recipe, you can change it to suit your family. Here are three variations that work well.
1. Kadha for cold and cough
Add 1 teaspoon of ajwain (carom seeds) and a small piece of mulethi (liquorice root) to the classic recipe. Ajwain helps clear a blocked nose, and mulethi soothes a sore throat and cough. Drink it warm, twice a day, for 3 to 5 days during a cold. If you want a fuller home-remedy plan for winter colds, our guide on Home Remedies for Cold and Cough in Winter: Ginger, Honey, Steam and When to See a Doctor covers ginger, honey, steam, and the warning signs that mean it is time to see a doctor.
2. Kadha without giloy (for daily use)
Giloy is strong and not meant for months of daily use. For a milder daily drink, skip the giloy and use tulsi, ginger, cinnamon, black pepper, and a little lemongrass or mint. This version is gentle enough for most healthy adults to drink 3 to 4 times a week in winter.
When to drink this immunity kadha recipe: timing matters
Best time: Early morning on an empty stomach is the most common time. The drink is warm, it wakes up digestion, and you can feel the ginger and pepper working.
Who should be careful with this immunity kadha recipe?
Kadha is a home drink, not a medicine, but it still has strong ingredients. Be careful if any of these apply to you:
- Pregnancy and breastfeeding: Giloy-based kadha is best avoided in pregnancy because there is not enough safety data for giloy.
- Children under 8: Do not give giloy kadha to young children. The milder version without giloy, in a small half-cup and with less spice, is a better choice for older children — and only if they like it. Never force a child to drink kadha. For foods that do support children’s immunity safely, see Immunity Booster Foods for Kids: 15 Indian Foods & Daily Diet Tips (Round 2 article).
- People with diabetes: Giloy can lower blood sugar. If you take diabetes medicine, check your sugar more often and tell your doctor you are drinking kadha.
- People on blood pressure or blood-thinning medicine: Ginger, giloy, and some spices can interact with these medicines. A small, occasional cup is usually fine, but a daily strong kadha deserves a quick check with your doctor.
- People with acidity, ulcers, or liver problems: The spices in kadha can worsen acidity. If you have liver disease, be extra careful with giloy — there have been reports of liver injury with long-term, high-dose giloy use. Stop kadha and see a doctor if you notice nausea that does not settle, dark urine, or yellowing of the eyes.
- People with autoimmune conditions: Because giloy stimulates the immune system, it may worsen conditions like rheumatoid arthritis or lupus. Ask your doctor before using a giloy-based kadha.
What does science say about immunity kadha recipe ingredients?
The National Center for Complementary and Integrative Health (NCCIH), part of the US National Institutes of Health, explains that Ayurvedic preparations have been studied in only a small number of well-designed trials, and that some Ayurvedic products can contain harmful metals if they are poorly made. Its page on Ayurvedic medicine in depth is a useful, balanced read before you start any Ayurvedic remedy, including kadha. It reminds readers not to use Ayurvedic medicine to delay seeing a doctor about a real health problem.
Common mistakes people make with an immunity kadha recipe
Drinking it all day, every day, for months. Kadha is meant for short spells — a week or two at a time.
Using kadha instead of a doctor. A fever that lasts more than 3 days, breathlessness, chest pain, a stiff neck, or a child who is not drinking fluids — these need medical care, not a stronger kadha.
Frequently Asked Questions
What is the best immunity kadha recipe for beginners?
Start with the classic version: giloy stem, tulsi, ginger, black pepper, and cinnamon boiled in 2 cups of water until it reduces to 1 cup. Strain, add a little honey, and drink half a cup twice a day. It is simple, cheap, and uses ingredients from any Indian kitchen.
Can I drink immunity kadha every day?
A mild kadha without giloy can be drunk a few times a week in winter. A giloy-based immunity kadha recipe should be used for 1 to 2 weeks at a time, then stopped for a break. Daily use for months is not advised, especially for people on diabetes or blood pressure medicine.
When is the best time to drink this immunity kadha recipe?
Early morning on an empty stomach is the usual time, with a second cup in the early evening if you are recovering from a cold. If kadha gives you acidity, drink it after breakfast instead. Avoid drinking it late at night.
Is this immunity kadha recipe safe for children?
Children under 8 should not drink giloy kadha. Older children can have a small half-cup of a milder kadha without giloy, with less pepper and ginger. Never force a child to drink it, and ask your paediatrician if your child takes regular medicine.
Can an immunity kadha recipe cure a cold or prevent COVID-19?
No. Kadha can soothe a sore throat and help you feel a little better during a cold, but it cannot cure a cold, prevent COVID-19, or replace medicine. If symptoms are severe or last more than a few days, see a doctor.
