What is Patala?

Patala is the root and root bark of a tree called Stereospermum suaveolens. The name is also written Stereospermum chelonoides. The tree grows in India and Southeast Asia.

In Ayurveda, Patala is used on its own for fever, cough, swelling and poor appetite. It is most often taken as a water decoction of the dried root bark.

It is best known as one of the Dashamoola, the classic group of ten roots. Most products you will meet hold Patala as one part in ten, not on its own.

Here is the honest verdict on the evidence. The traditional record is long and steady. But we could find no published human trials of Patala by itself.

Traditional use tells you what practitioners have done for many centuries. On its own, it does not prove the plant works. That point applies to everything on this page.

How does Patala work?

The short answer is simple. No one has shown how Patala works in people. The suggested ways it might work come from lab dishes and animal studies.

In Ayurveda, Patala is called bitter, astringent and drying. It is said to settle raised Vata and Kapha. That is a label inside a traditional system, not a measured effect in the body.

Lab work on Stereospermum extracts reports three things in cells and in rats. The extracts cut swelling, act as antioxidants, and lower blood sugar. These findings are early ones.

They do not tell you what a cup of decoction does in a human body. The doses given to animals are often far higher than the doses people take.

What forms does Patala come in?

Patala reaches you in a few forms:

Dried root bark, sold in pieces or shredded, for making a decoction (kwatha) at home.

Churna, a fine powder of the dried bark, taken with warm water or honey.

Dashamoola kwatha and Dashamoola churna, blends in which Patala is one of ten roots.

Dashamoolarishta, a traditional fermented liquid. It holds alcohol made during fermentation, often about 5 to 10 percent.

Here is a practical warning. Patala is one of the Ayurvedic roots most often swapped for something else. Bark from other trees is sometimes sold under the same name.

Buy from a supplier who names the plant species on the label.

Where it comes from:

Patala appears in the oldest Ayurvedic texts we still have. The Charaka Samhita and Sushruta Samhita both list it in the Dashamoola group of ten roots. Both were put together in the centuries around the start of the common era.

It sits in the Brihat Panchamoola, the five roots taken from trees. The others are Bilva, Agnimantha, Shyonaka and Gambhari.

Later Ayurvedic and Siddha writers kept it in the same place. They used it mainly for fever, breathing complaints and swelling.

Its standing in the tradition is solid and unbroken. That standing is about practice, not about trial results.

What does Patala help with?

• Fever and the thirst that comes with it: This is Patala's oldest traditional use. The classic texts name it for fever directly. It is given as a decoction, usually with the other Dashamoola roots. No human trials have tested Patala against fever. So treat this as tradition only. See a doctor for a fever above 39C (102F). See a doctor for any fever that lasts more than three days. A herb is not the right answer there.
• Cough and chest congestion: Dashamoola blends with Patala in them are a standard Ayurvedic choice for a wet, rattling cough. Animal studies on Stereospermum extracts report some drop in swelling. That is a long way from showing that a cough gets better in people. Nothing here treats asthma, pneumonia or COPD (a long-term lung disease).
• Swelling and joint pain: Patala is classed as a Vata-settling drug. It is used in traditional formulas for swelling and sore joints. Rat studies of Stereospermum extracts show less paw swelling. That is a common early screening test. No human trial has tested it for arthritis or any other joint problem.
• Poor appetite and sluggish digestion: The bitter, astringent taste is the traditional reason for this use. Bitters are used the same way in several food cultures. The evidence stops at that traditional reasoning. See a doctor if your appetite has been low for more than a few weeks. See a doctor if you are losing weight without trying.
• Recovery after childbirth (as part of Dashamoola): Dashamoola is a classic after-birth preparation in Ayurveda. Patala is one of its ten roots. This is a supervised traditional use, given by a practitioner after delivery. Do not treat yourself with it. Note that the fermented form holds alcohol. That matters if you are breastfeeding.
• Burning or discomfort on passing urine: Classic sources call Patala cooling and mildly diuretic (it makes you pass more urine). There is no human evidence for this. Burning urine with fever, back pain or blood means a urinary infection or worse. That needs medical treatment.

Which foods are rich in Patala?

Patala is a medicinal bark, not a food. It is not present in any normal diet.

What are the side effects of Patala?

• Nausea or stomach upset, most often from the bitter taste on an empty stomach
• Dry mouth from the astringent tannins
• Loose stools or, in some people, constipation
• Headache or flushing from the alcohol in fermented preparations
• Rash or itching from an allergic reaction (uncommon)
• Possible easier bruising or bleeding, based on the naphthoquinone content rather than on reports in people

Good to know:

Most reported problems are mild stomach complaints that settle when you stop. Patala has a long record of traditional use without reports of serious poisoning.

That said, it has never been through formal safety testing in humans, so rare or slow-building harms would not have been picked up. The clearest real-world risk is a product that is not actually Patala, since substitution with other barks is common. Stop and seek advice if you notice unusual bruising, bleeding gums or a rash.

How much Patala should you take?

• Recommended daily: No dose has been established by research. The figures below come from classical texts and current Ayurvedic practice. Dried root bark decoction: 40 to 80 mL once or twice a day, made by simmering about 5 to 10 g of bark in water until reduced. Churna (powder): 1 to 3 g a day, taken with warm water. Dashamoolarishta: usually 12 to 24 mL, diluted with an equal amount of water, twice a day. Remember it contains alcohol. Start at the low end. Do not stack a single-drug Patala powder on top of a Dashamoola blend that already contains it.
• Best time of day: Traditional practice gives the decoction in the morning and again in the early evening. Dashamoolarishta is usually taken after meals, twice a day.
• With or without food: Decoctions and powders are traditionally taken on an empty stomach, about 30 minutes before food. If it upsets your stomach, take it after eating instead. Fermented preparations such as Dashamoolarishta are taken after meals.
• Time to effect: Traditional use expects some change in fever or cough within one to three days. For appetite and digestion, practitioners look for change over one to two weeks. None of these timings has been tested in a trial.
• How long to take it: Short courses are the traditional pattern. For fever or a cough, two to seven days is usual, and you should stop and see a doctor if things are no better after three days. For digestion or joint complaints, two to four weeks is a reasonable trial. Reassess at that point rather than continuing out of habit. There is no safety data at all for continuous use beyond a few months.
