HelloPharmacist Scorecard of Tongkat Ali Extract by Herbadiet
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 is a single-ingredient supplement: Tongkat Ali root extract, made from the roots of the Eurycoma longifolia plant. It contains no other active ingredients and no inactive fillers or excipients.
Does it work?
Moderate evidence
The evidence for Tongkat Ali is limited. According to our data, it's possibly effective for boosting sexual desire.
For athletic performance, the evidence suggests it's possibly ineffective. For back pain, osteoporosis, and diabetes, we don't have enough reliable evidence to rate it one way or the other.
How safe is it?
Well-documented data
Tongkat Ali is generally well tolerated in short-term studies, but we don't have solid data on long-term safety or product quality across different brands. The research also raises a concern about hormonal effects.
If you're pregnant, the safety data advises against using it. If you're breastfeeding, there isn't enough reliable information — talk with your doctor or pharmacist about whether it's right for you.
One additional note: because the extract may raise testosterone, if your testosterone levels go above the normal range, there's a risk of testosterone-related side effects like acne, insulin resistance, and liver stress.
Meds to double-check
Moderate interaction found
Before you take this product, check with your doctor or pharmacist if you take propranolol (Inderal) or any other heart or blood pressure medication — Tongkat Ali can lower propranolol levels and reduce its effectiveness. Also double-check if you're on testosterone replacement therapy, or if you take medications broken down by your liver through the CYP1A2, CYP2C19, or CYP2A6 pathways.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Tongkat Ali might help with sexual desire, but the evidence is modest. If you take heart medications, blood pressure drugs, or testosterone replacement therapy, you'll need to check with your doctor or pharmacist first — this supplement can interfere with how they work.
Pregnant or breastfeeding? Skip it until you've talked it through with your healthcare provider.

Tongkat Ali root extract monograph & interactionsTongkat Ali Extract by Herbadiet Drug Interactions
HelloPharmacist Interaction Report
Herbadiet's Tongkat Ali Extract contains one active ingredient — Tongkat Ali root extract — which does interact with medications.
The most serious interaction is with propranolol (Inderal), a heart and blood pressure medication: the extract can lower propranolol's levels in your bloodstream and reduce how well it works, according to a clinical study.
Read the full breakdown — every affected drug type, severity by severity
Tongkat Ali may also affect how your liver breaks down certain other medications. Theoretically, it could increase levels of drugs metabolized by three liver enzymes (CYP1A2, CYP2C19, and CYP2A6 substrates), though these effects haven't been confirmed in humans — the evidence comes from lab studies.
Additionally, because Tongkat Ali may raise testosterone levels, it could theoretically increase testosterone further if you're already taking testosterone replacement therapy.
Altogether, these interactions span 248 individual medications. Before you start this product, run your exact medications through the search tool on this page, especially if you take propranolol or any heart, blood pressure, or hormone medications.

For each ingredient in Tongkat Ali Extract 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.
Tongkat Ali root extract
Propranolol (Inderal)
Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism. It is not known if separating administration will prevent this interaction.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes. This effect has not been reported in humans.
Cytochrome P450 2A6 (Cyp2A6) Substrates
Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes. This effect has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes. This effect has not been reported in humans.
Testosterone
Theoretically, Eurycoma longifolia may further increase levels of testosterone.
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo. It is unclear whether this increase would occur in individuals with normal testosterone levels.
