7 Immunity-Boosting Monsoon Drinks You Can Make at Home (India 2026)

Immunity drinks for monsoon in India are not just a trend. From June to September, more germs spread through water, food and the air. Your gut matters here too. The lymph tissue in your gut makes up almost 70% of the whole immune system, says a review in Clinical and Experimental Immunology. So clean food and water count as much as any drink.

My wife started making kadha for our family two months before monsoon this year. Our son (just over a year old now) had no stomach bugs last season, even when many families in our building fell sick. We cannot prove the drinks did this. Being careful about food and water likely helped just as much.

Here are the 7 immunity-boosting monsoon drinks we make at home. All of them use ingredients you already have in your Indian kitchen. None of them are expensive or complicated.

What Is the Best Immunity Booster Drink at Home?

An immunity booster drink at home is a simple drink made from kitchen spices or fruit, like kadha, haldi doodh or amla juice. The best one is the drink you will make every day with clean, boiled water. No single drink can stop a cold or a fever on its own. The science shows small effects at best.

Here is what the research says about each drink on this list:

• Amla juice: amla has 252 mg of vitamin C per 100 g, the most of any fruit in India's food tables (IFCT 2017, ICMR-NIN).
• Haldi doodh with black pepper: piperine in pepper raised curcumin absorption by 2000% in one small human study (Shoba and others, 1998).
• Tulsi tea: tulsi extract raised some immune markers in 22 healthy adults over 4 weeks (Mondal and others, 2011).
• Ginger-honey water: honey probably eases cough in children over 1 year (Cochrane review, 2018).
• Giloy water: giloy has been linked to liver injury in a study of 43 patients, so it needs a doctor's advice (Kulkarni and others, 2022).

Vitamin C does not prevent colds for most people. A Cochrane review pooled 29 trial comparisons with 11,306 people. Regular vitamin C did not lower the number of colds in the general public. It did make colds a little shorter: 8% shorter in adults and 14% in children (Hemila and Chalker, 2013).

Why Do People Fall Sick More in Monsoon?

People fall sick more in monsoon because more germs spread in these months. Rain can mix dirty water into pipes and wells. Typhoid spreads through contaminated food or water, says the World Health Organization. Cholera spreads the same way. Heavy monsoon rain is also linked to a higher risk of diarrhoea in children under five, a PLOS ONE study of Indian survey data found.

Study data point: A Mumbai hospital tested 2,860 samples for flu, RSV and COVID-19 from July 2022 to June 2025. The share of positive tests was highest every year in June to September, the monsoon and early post-monsoon months. Flu A was the most common virus (Chheda and others, Virusdisease 2026).

Traditional Indian monsoon drinks use ginger, turmeric, tulsi, amla and black pepper. Lab and animal studies show these have germ-fighting and anti-inflammatory effects. Human studies are fewer and smaller. So think of these drinks as good habits, not as medicine. Our ancestors made them long before anyone tested them.

1. Kadha - The Original Monsoon Immunity Booster

Kadha is a spiced herbal drink that Indian families have made in the monsoon and cold season for centuries. The word means "decoction" in Hindi. That is water in which herbs and spices simmer until the water takes on their taste and compounds.

A basic monsoon kadha recipe that works:

• 2 cups water
• 1 inch fresh ginger, roughly crushed
• 4 to 5 fresh tulsi leaves (or 1/4 teaspoon dried tulsi)
• 1/4 teaspoon turmeric powder
• 4 to 5 black peppercorns, lightly crushed
• 1 cinnamon stick or 1/4 teaspoon cinnamon powder
• 1 tablespoon honey (add after removing from heat - never boil honey)

Method: Bring 2 cups of water to boil in an electric kettle or on the stove. Add ginger, tulsi, turmeric, pepper, and cinnamon. Simmer on low heat for 8 to 10 minutes. Strain. Add honey once cooled slightly. Drink one cup in the morning, warm.

Why families drink it: Ginger, turmeric, black pepper and tulsi all have active compounds that labs have studied. Piperine in black pepper raised curcumin absorption by 2000%, or 20 times, in one small human study. But that study used 2 g of curcumin and 20 mg of piperine, much more than a cup of kadha holds (Shoba and others, 1998). There is no strong proof yet that kadha prevents colds. Read our honest guide to kadha for cold for the full story.

For a lighter, steeped kadha, use the InstaCuppa Electric Gooseneck Kettle. It has a 304 stainless steel tea infuser for the crushed spices and a built-in timer for the steeping time. It heats 1 litre of water and lets you pick a temperature from 40 to 100 °C, with stay warm and auto shut-off. It cost Rs 6,249 and was in stock on 12 October 2026. For a strong kadha that simmers for 10 minutes, use a pan on the stove.

2. Haldi Doodh (Golden Milk) - Before Bed Every Night in Monsoon

Haldi doodh is warm milk with turmeric, now known around the world as "golden milk". Curcumin is the main active compound in turmeric. Many studies have tested it. Still, the US National Center for Complementary and Integrative Health says we do not know enough to say turmeric or curcumin helps any health problem for sure (NCCIH: Turmeric). Read more in our guide to haldi doodh benefits.

Simple golden milk recipe:

• 1 cup full-fat milk (boiled)
• 1/2 teaspoon turmeric powder
• A pinch of black pepper (for curcumin absorption)
• 1/4 teaspoon ghee (optional, for taste)
• Honey to taste

Method: Heat milk until just simmering. Add turmeric, black pepper, and ghee. Stir well for 2 minutes. Remove from heat. Add honey. Drink warm before sleeping.

Do not skip the black pepper. Your body takes in very little curcumin on its own. In the small human study above, piperine from pepper raised curcumin absorption by 2000%. Many families also add ghee. Our grandmothers always added a pinch of pepper and a little ghee. One caution: do not swap haldi doodh for strong curcumin pills without a doctor. NCCIH warns that curcumin products made to absorb very well may harm the liver.

3. Amla Juice - One of the Richest Vitamin C Fruits in India

Amla (Indian gooseberry) has 252 mg of vitamin C per 100 g. That is the most of any fruit in the Indian Food Composition Tables 2017 from ICMR-NIN (IFCT 2017). It is about 6 times the vitamin C in orange pulp, which has about 43 mg. Guava comes close, at 214 to 222 mg. Vitamin C helps the immune system work. But extra vitamin C does not stop colds for most people, as the Cochrane review above found.

Fresh amla juice is best. If fresh amla is hard to find in the monsoon, good-quality amla powder or juice concentrate works too. For more ways to make it, see our amla juice recipe.

Fresh amla juice recipe:

• 3 to 4 fresh amla (Indian gooseberries)
• 1/2 cup water
• A pinch of black salt
• Honey to taste (optional)

Method: Cut the amla into small pieces and remove the seeds. Blend with water until smooth. Strain through a sieve. Add black salt and honey. Drink a small glass, about 50 to 100 ml, in the morning. The InstaCuppa Portable Blender (400 ml, 150 W, Rs 1,999) works for this. Its guide says to add the liquid first and cut food into small pieces.

Important: Amla juice is very sour. Some people drink it with a straw and rinse with water after, to go easy on their teeth.

4. Ginger-Honey Water - The Simplest Monsoon Morning Drink

Ginger-honey water is the easiest of the seven drinks. It takes about 3 minutes, and you need only two things most Indian homes already have. Many families make it at the first sign of a sore throat or a runny nose, which are common in the monsoon.

Recipe:

• 1 cup warm water (not boiling - just warm, around 50 degrees Celsius)
• 1 inch fresh ginger juice (grate ginger and squeeze)
• 1 tablespoon raw honey
• Optional: 1/2 teaspoon lemon juice

Method: Boil water in your electric kettle. Let it cool to around 50 degrees Celsius. A kettle with temperature control can hold it there for you. Add ginger juice and honey. Stir and drink. Add honey only once the water is warm, not boiling. Many families follow this habit from Ayurveda.

Ginger has been used for flu and colds in folk medicine since ancient times. The US NCCIH says ginger may help with nausea in pregnancy, but many ginger studies are not of high quality (NCCIH: Ginger). Honey has better proof for coughs. A Cochrane review found honey probably eases cough in children better than no treatment or a placebo. Never give honey to a baby under 1 year. It can cause infant botulism, a very serious illness, says the NHS. See our full guide to ginger water benefits.

5. Tulsi-Pepper Tea - A Warm Herbal Tea for Rainy Days

Tulsi (holy basil) is one of the most used Ayurvedic herbs in the monsoon. A review in the Journal of Ayurveda and Integrative Medicine says hundreds of lab, animal and human studies link tulsi to germ-fighting effects, including against viruses (Cohen, 2014). In a small trial, 22 healthy adults took tulsi leaf extract for 4 weeks, and some immune markers went up compared with a placebo. That was a 300 mg capsule of extract, not a cup of tea. So enjoy tulsi tea, but do not treat it as a shield against viruses. Read more about tulsi tea benefits.

Recipe:

• 1 cup water
• 8 to 10 fresh tulsi leaves (or 1/2 teaspoon dried tulsi)
• 3 to 4 black peppercorns, lightly crushed
• 1/4 teaspoon ginger (fresh or powder)
• Honey to taste

Method: Bring water to boil. Add tulsi leaves, peppercorns, and ginger. Simmer for 5 minutes on low flame. Strain and pour into a cup. Add honey after cooling slightly. Drink once or twice a day during monsoon.

If you grow tulsi at home (many Indian homes keep a tulsi plant), use fresh leaves. Wash them under running water first. Fresh leaves give a stronger smell and taste. Dried tulsi works well too.

6. ABC Juice (Apple, Beetroot, Carrot) - A Fresh Homemade Juice

ABC juice mixes apple, beetroot and carrot in one glass. Carrot gives beta-carotene, which the body can turn into vitamin A. Beetroot gives nitrates and a deep red colour. Apple adds natural sweetness, so you need no sugar. For the best ratio, see our ABC juice recipe.

You can find apple, beetroot and carrot in most Indian markets in the monsoon months. Making this juice at home is safer than buying it from a stall in the monsoon, because you control the washing and the water.

Recipe (makes 1 large glass):

• 1 medium apple (cored, chopped)
• 1 small beetroot (peeled, chopped)
• 2 medium carrots (peeled, chopped)
• 1/2 inch ginger
• 1/2 cup water
• A pinch of black salt

Method: Blend all the ingredients with the water until smooth, then strain. The InstaCuppa Portable Blender Bottle works for this. It has a 600 ml jar, a 6000 mAh battery with fast charging and an LED battery display, and its product page has a video on making ABC juice. It cost Rs 3,199 and was in stock on 12 October 2026. Our cold press juicer was sold out on that date. Drink ABC juice fresh. Put any leftover juice in the fridge at 0 to 5 °C straight away. The UK Food Standards Agency says to keep chilled food out of the fridge for the shortest time possible (FSA).

7. Giloy Water - A Traditional Drink with a Liver Warning

Giloy (Tinospora cordifolia) is called "Amrita" in Ayurveda, the nectar of immortality. The Ministry of AYUSH recommended it for COVID-19 care, says a 2023 review (Panneer Selvam and others). But giloy is not proven to cure fever. A study across 13 Indian hospitals found 43 patients with liver injury linked to giloy use. Some had acute liver failure (Kulkarni and others, Hepatology Communications 2022). The 2023 review says some cases may come from wrong plant species sold as giloy.

You can find giloy as dried stem pieces, powder or ready-made juice at Ayurvedic stores or online. Buy it only from a trusted, licensed brand, because other Tinospora species can be sold as giloy.

Recipe:

• 1 inch giloy stem (or 1 teaspoon giloy powder)
• 2 cups water
• Optional: 4 to 5 tulsi leaves, 1/4 teaspoon black pepper

Method: Boil giloy stem (or powder) in 2 cups of water for 10 to 15 minutes until the water reduces to about 1 cup. Strain. Drink warm. Ask your doctor before you take it, and ask how long to take it. If you have a fever, see a doctor. Giloy water is not a fever cure.

Note: If you are on diabetes medication, or have an autoimmune condition or liver disease, check with your doctor before taking giloy. In the 2022 study, worsening of existing liver disease was the most common problem. Stop giloy and see a doctor if you get yellow eyes or skin.

Which Juice Is Best in Rainy Season?

The best juice in rainy season is a fresh juice you make at home from washed fruit, like amla juice or ABC juice. Use boiled and cooled water, and drink it soon after you make it. Skip street juice and ice in the monsoon. Typhoid and cholera both spread through contaminated food or water, says the World Health Organization.

Which fruit juice is good in rainy season?

Amla juice is a good fruit juice in rainy season, because amla has the most vitamin C of any fruit in IFCT 2017. Guava juice is close behind. Wash the fruit under running water and rub the skin, as the UK Food Standards Agency advises. For fruits that are in season in the rains, see our guide to monsoon fruits in India.

Which drink is best in rainy season?

The best drink in monsoon is safe water. Boil it, or use a purifier that is serviced on time. A rolling boil for at least one minute kills germs like bacteria and viruses, says the US EPA. After water, warm drinks like kadha, ginger water and tulsi tea are good choices, because you make them with boiled water. Ayurveda's monsoon routine also advises boiled water (Ritucharya review, AYU journal).

How to Make These Drinks Safely in Monsoon

Even immunity drinks can become a source of contamination if made with unclean water or ingredients. Follow these rules:

1. Always use boiled water. For kadha, haldi doodh, ginger water, and tulsi tea - the water boils during preparation so it is safe. For drinks like ginger-honey water where water is just "warm," start with previously boiled water.
2. Wash fresh ingredients well. Ginger, tulsi, amla and beetroot can carry mud and dirty rain water in the monsoon. Wash them under a running tap and rub the skin, as the UK Food Standards Agency advises.
3. Make these drinks fresh. Make them daily or before each serving. Cool any leftover drink and put it in the fridge within one to two hours, as the UK Food Standards Agency advises. Germs grow fast in warm air.
4. Use glass or stainless steel containers. Many families prefer them for hot drinks over plastic. They are easy to clean well.
5. Add honey last. Add honey after the drink has cooled to around 50 degrees Celsius or below, as Ayurveda advises. Never give honey to a baby under 1 year.
