HelloPharmacist Scorecard of Anise 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
Herbal Terra's Anise is a single-ingredient liquid extract: certified organic anise dried seed. It's made using a menstruum (a liquid used to extract the plant's active compounds) to concentrate anise's components into liquid form.
Anise seed has been used traditionally for digestive comfort and other purposes, and this product delivers it in a concentrated liquid format for easy dosing.
Does it work?
Couldn't assess
The evidence for anise's effectiveness isn't established in the data we hold. We have insufficient reliable evidence to rate it for migraine headache, lice, menopausal symptoms, premenstrual syndrome (PMS), or dysmenorrhea (period pain).
If you're considering anise for one of these uses, talk with your doctor or pharmacist about whether the research supports it and whether it's the right choice for you.
How safe is it?
Well-documented data
Anise is generally well tolerated when taken by mouth, and it's considered likely safe during pregnancy and breastfeeding. The concentrated essential oil, however, needs more caution — the safety data on medicinal amounts and the essential oil is limited, so avoid those forms during pregnancy.
Allergic reactions are rare but possible, especially in sensitive individuals. Topically, anise can cause contact dermatitis (skin irritation).
Very rarely, oral use has triggered anaphylaxis in people with sensitivity. If you've had allergic reactions to anise or related plants before, steer clear of this product.
Meds to double-check
Moderate interaction found
Before taking this product, check with your doctor or pharmacist if you take antidiabetes drugs (insulin or oral medications), fluoxetine (Prozac), imipramine (Tofranil), codeine, diazepam (Valium), caffeine-containing medications, estrogen-based hormone replacement therapy, or birth control pills. Most of these interactions are theoretical and based on animal research, but they're worth confirming with your own healthcare provider.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Anise seed extract is generally well tolerated and considered safe during pregnancy and breastfeeding, but the evidence for what it actually does isn't established in our data. The bigger concern is interaction potential with diabetes medications, certain antidepressants, and a handful of others — most based on animal studies, not human ones.
If you take any prescription medication, especially for blood sugar or mood, check your specific drugs with your doctor or pharmacist before starting.

Anise by Herbal Terra Drug Interactions
HelloPharmacist Interaction Report
Herbal Terra's Anise liquid extract does interact with a number of medications, and there are some important ones to flag before you start.
Read the full breakdown — every affected drug type, severity by severity
The most serious theoretical concern is with blood sugar medications (antidiabetes drugs). A small clinical study found that anise seed powder lowered fasting blood glucose by 36% compared to baseline, which means taking anise alongside diabetes medications could theoretically raise your risk of low blood sugar (hypoglycemia).
If you take insulin or any oral diabetes drug, this is worth discussing with your doctor or pharmacist before adding anise.
Animal studies also suggest anise oil may interfere with how your body handles several other medications. It might reduce the effectiveness of certain antidepressants — fluoxetine (Prozac) and imipramine (Tofranil) — or caffeine, possibly by speeding up how your liver breaks them down.
On the flip side, it may increase the effects of codeine or diazepam (Valium), which could heighten side effects. Anise may also theoretically interfere with estrogen-based hormone replacement therapy and birth control pills, though the research is mixed on whether it acts like estrogen or against it.
Almost all of these findings come from animal studies, and whether they actually occur in people remains unclear. Altogether, these interactions span 245 individual medications.

Antidiabetes Drugs
Theoretically, anise seed might increase the risk of hypoglycemia when taken with antidiabetes drugs.
A small clinical study shows that anise seed powder decreases fasting blood glucose levels by 36% when compared to baseline.
Caffeine
Theoretically, anise oil might decrease the efficacy of caffeine.
Animal research shows that taking anise oil with caffeine decreases the bioavailability of caffeine. Whether this interaction will occur in humans is unclear.
Codeine
Theoretically, anise oil might increase the effects and adverse effects of codeine.
Animal research shows that anise oil increases the analgesic effects of codeine, possibly by inducing its phase I metabolism and increasing conversion to morphine. Whether this interaction occurs in humans is unclear.
Contraceptive Drugs
Theoretically, anise might interfere with contraceptive drug therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.
Diazepam (Valium)
Theoretically, anise oil might increase the effects and adverse effects of diazepam.
Animal research shows that taking anise oil with diazepam increases the motor impairment associated with diazepam, possibly by inhibiting its breakdown by cytochrome P450 3A4. Whether this interaction occurs in humans is unclear.
Estrogens
Theoretically, anise might interfere with estrogen-based hormone replacement therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.
Fluoxetine (Prozac)
Theoretically, anise oil might decrease the efficacy of fluoxetine.
Animal research shows that taking anise oil with fluoxetine reduces the antidepressant effects of fluoxetine, possibly by promoting its breakdown by cytochrome P450 2D6. Whether this interaction occurs in humans is unclear.
Imipramine (Tofranil)
Theoretically, anise oil might decrease the efficacy of imipramine.
Animal research shows that taking anise oil with imipramine reduces the antidepressant effects of imipramine, possibly by promoting its breakdown by cytochrome P450 2D6. Whether this interaction occurs in humans is unclear.
Midazolam (Versed)
Theoretically, anise oil might increase the effects and adverse effects of midazolam.
Animal research shows that taking anise oil with midazolam increases the motor impairment associated with midazolam, possibly by inhibiting its breakdown by cytochrome P450 3A4. Whether this interaction occurs in humans is unclear.
Tamoxifen (Nolvadex)
Theoretically, anise might interfere with tamoxifen therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.
Acetaminophen (Tylenol, Others)
Theoretically, anise oil might decrease the levels and clinical effects of acetaminophen.
Animal research shows that taking anise oil with acetaminophen decreases peak plasma levels of acetaminophen but does not reduce overall bioavailability. Whether this interaction will occur in humans is unclear.
