Tulsi Tea Benefits: Why Every Indian Home Swears by Holy Basil

By Saran Reddy · Founder, InstaCuppa | Last updated: 24 September 2026

The tulsi tea benefits that Indian grandmothers have sworn by for generations now have solid science behind them. Tulsi — holy basil — grows in almost every Indian home. Your grandmother probably has a tulsi plant on the balcony or in the courtyard. But most people just water it and pray near it. Few actually make tea from it. That is a missed chance. Tulsi tea may be one of the healthiest drinks you can brew at home, and it takes less than five minutes.

Tulsi Tea Benefits: What the Research Actually Shows

Tulsi tea is holy basil leaves steeped in hot water. The one review of human trials pooled 24 studies. It found tulsi may help with blood sugar, blood pressure, blood fats and stress. Fifteen of the 24 studies reported no side effects. The gains are real but small, and most trials were short.

The reviewers call tulsi “a safe herbal intervention that may assist in normalising glucose, blood pressure and lipid profiles” (Jamshidi and Cohen, 2017).

One number is worth knowing. In a trial of adults with type 2 diabetes, holy basil leaves cut fasting blood sugar by 21.0 mg/dl. That is a drop of 17.6 per cent (Agrawal, Rai and Singh, 1996). That trial used leaf powder with meals. It did not use a cup of tea. So drink tulsi tea as a daily habit. It is not a medicine. It replaces nothing your doctor has given you.

What Is Tulsi Tea and Why Do Indian Homes Trust It?

Tulsi tea is made from the leaves of the holy basil plant (Ocimum tenuiflorum). In Ayurveda, tulsi is called "The Queen of Herbs" and has been used for thousands of years to support immunity, reduce stress, and fight respiratory problems.

Tulsi is not the same as the Italian basil you use in pasta. Indian tulsi has a sharper, peppery taste with hints of clove. There are three main types: Rama tulsi (mild, light green), Krishna tulsi (purple, stronger flavour), and Vana tulsi (wild, most pungent). All three make excellent tea.

In Indian households, tulsi is more than a herb — it is considered sacred. But beyond the spiritual connection, modern studies are catching up to what Ayurveda has known for centuries. Tulsi is a powerful adaptogen that may help your body handle stress better.

What Are the Health Benefits of Drinking Tulsi Tea?

Tulsi may help with stress, immunity, respiratory health, blood sugar management, and inflammation. It is an adaptogen — a natural compound that helps your body respond to physical and mental stress.

• Stress relief: Tulsi is classified as an adaptogen. Studies suggest it may lower cortisol levels and help you feel calmer. A cup in the evening can help you unwind after a long day.
• Immunity: Tulsi has antimicrobial and antiviral properties. It has been traditionally used to fight colds, coughs, and fever. Some studies support its role in boosting immune response.
• Respiratory health: Tulsi may help open airways and ease breathing. It is commonly used in home remedies for cough, bronchitis, and asthma symptoms.
• Blood sugar: Some research suggests tulsi may help lower fasting blood sugar. This is promising, but do not replace diabetes medication with tulsi tea.
• Anti-inflammatory: Compounds like eugenol in tulsi may help reduce swelling and pain. This is the same compound that gives cloves their pain-relieving properties.
• Digestion: Tulsi may stimulate digestion and reduce bloating. Drinking it after meals is a common Ayurvedic practice.

Important note: tulsi tea may support your health, but it is not a cure for any disease. Think of it as a daily wellness habit, not a medicine.

How Do You Make Tulsi Tea at Home?

Pick 8-10 fresh tulsi leaves, wash them, and steep in hot water (100°C) for 5 minutes. You can also use dried tulsi leaves or tulsi powder. Add honey and lemon for extra flavour.

Fresh Tulsi Leaves Method

1. Pick 8-10 fresh tulsi leaves. Rinse them gently.
2. Lightly tear or bruise the leaves to release their oils.
3. Place the leaves in the strainer of your InstaCuppa Borosilicate Glass Teapot with removable steel infuser.
4. Pour boiling water (100°C) over the leaves.
5. Steep for 5 minutes with the lid on.
6. Remove the strainer. Add honey and a squeeze of lemon if you like.

Dried Tulsi Method

If you do not have a fresh plant, dried tulsi works well. Use 1 teaspoon of dried tulsi per cup. Steep for 5-7 minutes. Dried tulsi has a more concentrated flavour than fresh leaves, so you need less.

Tulsi with Green Tea

For an antioxidant boost, add half a teaspoon of green tea leaves along with the tulsi. Use water at 80°C (not boiling) and steep for 3 minutes. This gives you the benefits of both plants in one cup.

Should You Use Fresh or Dried Tulsi for Tea?

Fresh tulsi gives a brighter, more aromatic cup. Dried tulsi is stronger and more convenient. Both work. If you have a tulsi plant at home, use fresh. If not, buy dried tulsi from any Ayurvedic store or online.

Fresh leaves lose their potency within a day after picking, so use them right away. Dried tulsi stores well for 6-12 months in an airtight container. Many brands sell dried tulsi tea — look for organic, single-origin options.

Are There Any Side Effects of Tulsi Tea?

Tulsi is safe for most people in normal amounts (1-2 cups per day). But it may lower blood sugar and slow blood clotting, so people on diabetes or blood-thinning medication should check with their doctor first.

• Blood sugar: Tulsi may lower blood sugar. If you take diabetes medication, monitor your levels closely.
• Blood clotting: Tulsi may slow blood clotting. Stop drinking it 2 weeks before any surgery.
• Pregnancy: Some Ayurvedic texts advise caution during pregnancy. Check with your doctor.
• Fertility: Very high doses of tulsi may affect sperm count in animal studies. Normal tea amounts are unlikely to cause issues in humans.

For most healthy adults, 1-2 cups of tulsi tea daily is perfectly safe and beneficial.

What Are Some Easy Tulsi Tea Variations?

Mix tulsi with ginger for cold relief, with cinnamon for warmth, with lemon and honey for a morning boost, or with chamomile for a calming bedtime drink.

• Tulsi + ginger: The classic Indian cold remedy. Crush ginger and tulsi together, steep in hot water. Add honey.
• Tulsi + cinnamon: Warming and slightly sweet. Break a cinnamon stick and add it to the infuser with the tulsi leaves.
• Tulsi + lemon + honey: A morning detox drink. Brew tulsi, cool slightly, add lemon juice and honey.
• Tulsi + chamomile: A bedtime blend. The chamomile adds a mild, calming note to the peppery tulsi.
• Tulsi + black pepper: A traditional Ayurvedic combination for respiratory health. Add 3-4 crushed black peppercorns to the infuser with tulsi.
