HelloPharmacist Scorecard of Tongkat Ali Alcohol Free by Herbal Terra
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: Tongkat Ali root extract (from Eurycoma longifolia). The liquid formula also includes glycerin and water as inactive ingredients to deliver the extract.
Does it work?
Moderate evidence
Tongkat Ali is possibly effective for sexual desire based on the evidence we have on file. For athletic performance, the data suggests it's possibly ineffective.
The evidence for back pain, osteoporosis, and diabetes isn't reliable or complete enough to rate, so we can't say whether it helps with those.
How safe is it?
Well-documented data
Tongkat Ali is generally well tolerated in short-term studies, but long-term safety data is limited and product quality can vary. Because the extract may increase testosterone levels, some people could develop testosterone-related side effects — including acne, insulin resistance, and liver concerns — if their testosterone rises beyond the normal range.
The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know it's safe in those situations.
Meds to double-check
Moderate interaction found
Double-check propranolol (Inderal) or other blood pressure medications — Tongkat Ali can reduce their effectiveness. Also verify any testosterone replacement therapy you're on, and ask your pharmacist about any other drugs your liver metabolizes before starting this product.
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 may be worth considering if you're interested in sexual desire support and don't take propranolol or hormone therapies. If you're on any prescription medications, especially blood pressure drugs or those your liver metabolizes, check with your pharmacist first.
Avoid it if you're pregnant or breastfeeding.

For each ingredient in Tongkat Ali Alcohol Free 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, Dry
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.
