What is this page for?

First and foremost: how Stereospermum interacts with medications. The heart of this page is the interaction list — every drug Stereospermum is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Stereospermum is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

Stereospermum Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the overall risk of a clinically significant Stereospermum drug interaction appears low for most people, though those taking diabetes medications should be more careful. None of the listed interactions are rated major, and every one traces back to a single, unproven concern about blood sugar.

Interactions deserving the most attention

The only interaction that stands out involves diabetes medications such as glimepiride and glyburide. Animal research suggests Stereospermum may lower blood sugar, so combining it with these drugs could, in theory, push blood sugar too low. This effect has not been shown in humans, but because blood sugar control is closely monitored and low blood sugar can be serious, we think this combination deserves the most caution.

What the rest of the list means

Although the list of interacting medications looks long, it does not mean each combination is known to be harmful. Nearly all of these entries come from the same theoretical blood sugar concern, which so far rests on animal studies rather than human evidence. In other words, one unproven finding accounts for the entire list.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Antidiabetes Drugs

Animal research suggests that stereospermum can have hypoglycemic effects. This has not been shown in humans. Until more is known, use cautiously in patients taking antidiabetes drugs. Theoretically, concomitant use with antidiabetes drugs might affect glucose control and increase the risk of hypoglycemia.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.

Stereospermum: Uses, Safety & Side Effects

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Reviewed June 2026 ·

The bottom line

Stereospermum is a tree used in traditional Ayurvedic medicine, most notably as one of the herbs in the classic 'Dashamula' (ten-root) formula. There is very little high-quality human research to confirm its benefits, so its uses remain largely traditional. If you are considering it, talk with a pharmacist or doctor first, especially if you are pregnant, breastfeeding, or taking other medicines.

Scientific name: Stereospermum suaveolens
Family: Bignoniaceae

Overview

Stereospermum is a flowering tree in the Bignoniaceae family that grows in parts of India and other regions of South and Southeast Asia. Stereospermum suaveolens (sometimes listed under related species names) is the form most often mentioned in traditional medicine.

In Ayurveda, this plant is known by names such as Patala and is best known as one of the ten roots in the well-known Dashamula formula. The root bark, stem bark, leaves, and flowers have all been used in traditional preparations.

People have traditionally used it as a decoction, powder, or as part of multi-herb blends rather than as a standalone modern supplement.

Uses & effectiveness

Stereospermum has a long history of traditional use, but modern scientific evidence is limited. Most studies so far are laboratory or animal experiments, not well-designed human trials.

Traditionally it has been used for:

Fever and inflammation
Pain
Digestive complaints
Respiratory problems such as cough
As a general restorative tonic

Some early laboratory and animal research suggests possible anti-inflammatory, antioxidant, and pain-relieving activity. However, these findings are preliminary and do not prove that the herb works in people. There is not enough reliable human evidence to recommend it for any specific health condition.

How it works

Researchers have identified several natural compounds in Stereospermum, including substances such as lapachol-type quinones, flavonoids, and other plant chemicals (phytochemicals). In laboratory and animal studies, some of these compounds have shown antioxidant and anti-inflammatory effects.

The idea is that these compounds may help reduce inflammation or neutralize harmful molecules called free radicals. However, it is important to understand that these are proposed mechanisms based mostly on test-tube and animal work. We do not have strong evidence on how it behaves in the human body.

Safety & precautions

The safety of Stereospermum in humans has not been well studied. Because reliable data are lacking, you should be cautious before using it.

Pregnancy and breastfeeding: There is not enough information to consider it safe. To be on the safe side, women who are pregnant or breastfeeding should avoid using it.

People with chronic health conditions, those taking prescription medicines, older adults, and children should speak with a healthcare professional before trying it. Quality and purity of herbal products can vary widely, so choose products from reputable manufacturers and always check with a pharmacist or doctor first.

Side effects

Because there is so little human research, the full side effect profile is not known. Traditional use has not clearly documented serious harm, but this is not the same as proof of safety.

As with many herbal products, possible reactions could include stomach upset, nausea, or allergic reactions in sensitive people. If you notice rash, swelling, trouble breathing, or any unusual symptoms, stop using it and seek medical care right away.

Dosing

There is no well-established standardized dose for Stereospermum. Traditional preparations vary, and it is often used as part of multi-herb formulas rather than alone.

If you choose to use a product that contains it, follow the directions on the product label and do not exceed the recommended amount. Because doses and product strengths differ, it is best to check with a pharmacist or doctor before starting.
