HelloPharmacist Scorecard of Pippali Powder by Vedic Powders
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: Piper longum, Powder — commonly called Indian long pepper. It's a traditional spice that contains a compound called piperine, which is responsible for both its flavor and its effects on your body.
There are no inactive ingredients listed.
Does it work?
Couldn't assess
The evidence we hold doesn't establish that Indian long pepper works for any of the conditions it's traditionally used for — including bronchitis, asthma, cancer, cardiovascular disease, or liver disease. All of these are rated as having insufficient reliable evidence.
That doesn't mean it doesn't work; it means the research isn't solid enough yet to make a confident claim.
How safe is it?
Some data gaps
As a food spice, Indian long pepper is likely fine. But concentrated supplements like this powder lack strong safety data, and piperine can significantly affect how your body absorbs other substances — which is why the interactions matter.
During pregnancy, medicinal amounts of this supplement are traditionally discouraged and not well studied, so it's best to avoid it. The same goes for breastfeeding — there isn't enough safety information to recommend it in supplement doses.
Meds to double-check
Moderate interaction found
Check before using this if you take blood thinners (like warfarin or aspirin), propranolol or other heart medications, drugs that lower blood sugar, theophylline, cyclosporine, pentobarbital, or any medication metabolized by your liver — which is a lot of them. All of these carry Moderate interactions with piperine, the active compound in this powder.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.
If you use this as an occasional cooking spice in small amounts, you're probably okay. But if you're taking it as a supplement and you're on any regular medications — especially blood thinners, heart drugs, diabetes medications, or anything your liver processes — check with your pharmacist first.
The interaction potential is real and significant.
Educational only — not medical advice; always confirm with your pharmacist. Our editorial policy · How we use AI

HelloPharmacist Interaction Report
Pippali Powder by Vedic Powders contains Indian long pepper, which does interact with medications.
The most serious concern is with blood thinners (anticoagulant/antiplatelet drugs) — the active compound piperine in this powder can inhibit platelet aggregation, theoretically raising your bleeding risk.
Read the full breakdown — every affected drug type, severity by severity
Beyond that, there are several other Moderate interactions to watch for. The powder may increase blood levels of propranolol (a heart medication), theophylline (a respiratory drug), and cyclosporine (an immunosuppressant), potentially boosting their effects and side effects.
It can also inhibit a major liver enzyme (CYP3A4) and a cellular pump (P-glycoprotein), both of which affect how your body processes many common drugs — including some statins, antihistamines, and cancer medications. Additionally, piperine may lower blood sugar, raising the risk of low blood sugar (hypoglycemia) if you take diabetes drugs, and it may intensify the sedative effects of pentobarbital.
Altogether, these interactions span 897 individual medications. Use the medication checker on this page to look up your exact prescriptions before you start this supplement.

For each ingredient in Pippali Powder with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Piper longum, Powder
Anticoagulant/Antiplatelet Drugs
Theoretically, Indian long pepper might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
In vitro research shows that Indian long pepper extract inhibits platelet aggregation.
Antidiabetes Drugs
Theoretically, Indian long pepper might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that piperine, a constituent of Indian long pepper, can reduce blood glucose levels. Monitor blood glucose levels closely. Dose adjustments might be necessary.
Cyclosporine (Neoral, Sandimmune)
Theoretically, Indian long pepper might increase the effects and adverse effects of cyclosporine.
In vitro research shows that piperine, a constituent of Indian long pepper, increases the bioavailability of cyclosporine.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, Indian long pepper might increase the effects and adverse effects of CYP3A4 substrates.
In vitro research shows that piperine, a constituent of Indian long pepper, inhibits CYP3A4.
Nevirapine (Viramune)
Theoretically, Indian long pepper might increase blood levels of nevirapine.
A small pharmacokinetic study shows that piperine, a constituent of Indian long pepper, increases the plasma concentration and systemic exposure of nevirapine. However, no adverse effects were associated with the elevated plasma levels of nevirapine.
P-Glycoprotein Substrates
Theoretically, Indian long pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of Indian long pepper, can inhibit P-glycoprotein.
Pentobarbital (Nembutal)
Theoretically, Indian long pepper might increase the sedative effects of pentobarbital.
Animal research shows that piperine, a constituent of Indian long pepper, can increase pentobarbitone-induced sleeping time.
Phenytoin (Dilantin)
Theoretically, Indian long pepper might increase blood levels of phenytoin.
A small pharmacokinetic study shows that piperine, a constituent of Indian long pepper, increases phenytoin serum levels and slows its elimination.
Propranolol (Inderal)
Theoretically, Indian long pepper might increase blood levels of propranolol.
A small pharmacokinetic study shows that piperine, a constituent of Indian long pepper, accelerates absorption and increases serum concentrations of propranolol.
Rifampin (Rifadin)
Theoretically, Indian long pepper might increase blood levels of rifampin.
Piperine, a constituent of Indian long pepper, seems to increase absorption and serum levels of rifampin.
Theophylline
Indian long pepper might increase blood levels of theophylline.
A small pharmacokinetic study shows that piperine, a constituent of Indian long pepper, increases serum concentrations and slows elimination of theophylline.
Amoxicillin (Amoxil, Trimox)
Theoretically, Indian long pepper might increase the effects and adverse effects of amoxicillin.
Evidence from animal research shows that piperine, a constituent of Indian long pepper, increases the plasma levels of amoxicillin when taken concomitantly.
Carbamazepine (Tegretol)
Theoretically, Indian long pepper might increase blood levels of carbamazepine.
A small pharmacokinetic study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that a single 20 mg dose of purified piperine, which is a constituent of Indian long pepper, increases carbamazepine levels. Piperine may increase absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or by cytochrome P450 3A4 (CYP3A4) inhibition in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects.
Cefotaxime (Claforan)
Theoretically, Indian long pepper might increase the effects and adverse effects of cefotaxime.
Animal research shows that piperine, a constituent of Indian long pepper, increases the plasma levels of cefotaxime when taken concomitantly.
