Nannari Sarbath Recipe: South India's Natural Body Coolant (2026)

What Is Nannari Sarbath? South India's Summer Secret

Nannari sarbath is a traditional South Indian cooling drink made from the roots of the nannari plant (Hemidesmus indicus), also called Indian sarsaparilla. The word nannari means "good roots" in Tamil. This drink has been made in Tamil Nadu and Kerala homes for over 2,000 years as a natural remedy for summer heat.

I first had nannari sarbath at a roadside stall in Chennai when I was visiting family. The vendor mixed a dark amber syrup with cold water and handed it to me in a steel tumbler. It was unlike any drink I had tasted - earthy, slightly sweet, with a cooling sensation that lasted for hours. I immediately asked how to make it at home.

The Siddha Medicine Heritage Behind Nannari

Nannari root (Hemidesmus indicus) is one of the most documented herbs in Indian traditional medicine. It has more than 2,000 years of use in Ayurveda, Siddha, and Unani systems. In Siddha medicine from Tamil Nadu, it is classified as a "sheeta virya" herb - meaning it is cooling in nature and reduces body heat.

Siddha classification: Nannari is used in over 60 classical Siddha formulations, primarily for its body-cooling, blood-purifying, and diuretic properties - Siddha Pharmacopoeia of India, Vol. I.

The plant grows as a twining shrub in dry areas across South India, Sri Lanka, and Southeast Asia. The roots are dried and sold as dark brown sticks with a distinctive earthy, vanilla-like aroma. This aroma comes from the compound 2-hydroxy-4-methoxybenzaldehyde, which gives nannari its unique flavor.

5 Key Cooling Benefits of Nannari

Nannari provides five well-documented health benefits that make it especially valuable in South India's hot summers.

1. Reduces Body Heat (Natural Coolant)

This is nannari's most famous benefit. The root reduces internal body temperature by improving kidney filtration and promoting light sweating. It is traditionally given during heat strokes and summer fatigue. One glass of nannari sarbath in the afternoon provides hours of cooling relief.

2. Supports Kidney Health

Nannari acts as a gentle diuretic. It increases urine output, which flushes kidney toxins. Traditional Siddha practitioners used it to prevent kidney stones and urinary tract infections during summer.

3. Blood Purification Support

The saponins and tannins in nannari root support liver function. A healthier liver processes blood toxins more effectively. This is why many Indian grandmothers prescribe nannari sarbath for skin problems like pimples and rashes - the liver connection is real.

4. Relieves Digestive Discomfort

Nannari has mild anti-inflammatory properties. It soothes the stomach lining and reduces acidity. Drinking nannari sarbath after a heavy meal can ease the heaviness and bloating.

5. Prevents Heat Stroke Symptoms

The electrolytes and cooling compounds in nannari sarbath help maintain fluid balance. This prevents the headaches, fatigue, and nausea that come with exposure to intense summer heat.

How to Make Nannari Syrup at Home (From Scratch)

Making nannari syrup at home is the traditional method. Store-bought syrups often have artificial flavors and preservatives. Homemade syrup keeps in the fridge for 2 to 3 months and gives a far better flavor.

Ingredients (makes 500 ml syrup):

• 50 g dried nannari roots (available at Indian herbal stores, Khari Baoli, or Amazon)
• 500 ml water
• 300 g sugar (or equivalent jaggery for a more traditional version)
• Juice of 1 lemon (added after cooling - prevents crystallization)

Steps for Nannari Syrup:

1. Wash the dried nannari roots under running water to remove dust.
2. Add roots and 500 ml water to a heavy-bottomed pan. Bring to a boil.
3. Reduce heat and simmer for 30 minutes. The water will turn dark amber and fragrant.
4. Strain the liquid through a fine mesh. Discard the roots.
5. Add sugar to the strained liquid. Stir until dissolved.
6. Simmer again for 10 to 15 minutes until the syrup reaches a one-string consistency. (Drop a little on a plate - it should form a thin string between your fingers.)
7. Turn off heat. Let the syrup cool completely.
8. Add lemon juice and stir. The lemon prevents sugar crystallization in the fridge.
9. Pour into a clean glass bottle. Store in the fridge.
