HelloPharmacist Scorecard of Anise 450 mg 4:1 Extract by TerraVita Premium Collection

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
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: anise extract, a concentrated form of the anise seed (a 4:1 extract means four parts of the plant material were used to make one part of the extract). The other ingredients are gelatin and water, which serve as the capsule material and base.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Anise product and its label doesn't state a use — see Anise's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold does not establish that anise is effective for the uses commonly claimed — migraine headache, lice, menopausal symptoms, PMS, and dysmenorrhea all have insufficient reliable evidence to rate. A small clinical study did show that anise seed powder lowered fasting blood glucose levels by 36% compared to baseline, but that's a single study and doesn't establish broad effectiveness for blood sugar control.

The evidence, ingredient by ingredient Anise

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Anise is generally well tolerated when taken orally. The most common side effect from topical use is contact dermatitis (skin irritation) in sensitive people, and rare but serious allergic reactions — including anaphylaxis, occupational asthma, and rhinoconjunctivitis — have been reported orally or by inhalation in those with sensitivities.

The safety data advises against medicinal amounts and the concentrated essential oil during pregnancy due to limited safety information, though anise as a food or tea is generally considered safe.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Anise.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 245 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check with your doctor or pharmacist if you use estrogens or contraceptive drugs (anise may theoretically interfere with how they work), antidiabetes drugs (anise may increase the risk of low blood sugar), or fluoxetine (Prozac), caffeine, codeine, diazepam (Valium), or imipramine (Tofranil) — all Moderate-severity interactions are documented. Use the interaction tool on this page with your exact medications.

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 extract may be worth considering if you're curious about traditional uses, but the evidence for its effectiveness isn't established in the data we hold. If you take any medications — especially birth control, diabetes drugs, antidepressants, or sedatives — run them through the interaction checker on this page before starting.

Talk it over with your own doctor or pharmacist, especially if you're pregnant, sensitive to foods or herbs, or take multiple medications.

A small clinical study shows that anise seed powder decreases fasting blood glucose levels by 36% when compared to baseline.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Anise 450 mg 4:1 Extract by TerraVita Premium Collection: Common Questions

Does Anise 450 mg 4:1 Extract by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Anise 450 mg 4:1 Extract has a known interaction with 245 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Anise 450 mg 4:1 Extract contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe during pregnancy?
Safety data advises against medicinal amounts and the concentrated essential oil during pregnancy because there isn't enough information to know it's safe. Anise as a food or tea is generally considered safe, but this is a concentrated extract. Talk with your doctor or pharmacist about whether it's right for you.
Can I take it if I'm allergic to other herbs or foods?
People with sensitivities to anise or related plants (like celery, carrot, and coriander) can have allergic reactions — ranging from contact dermatitis and respiratory symptoms to anaphylaxis. If you have food allergies or a history of reactions to herbs, tell your doctor or pharmacist before trying this.
Does anise actually work for migraines or PMS?
The evidence we hold doesn't establish that anise is effective for migraine, PMS, dysmenorrhea, menopausal symptoms, or lice — all are rated as having insufficient reliable evidence. That doesn't mean it doesn't work, just that the data to prove it isn't there yet.
What are the common side effects?
Taken orally, anise is generally well tolerated with few side effects. Topically, it can cause contact dermatitis (skin irritation) in sensitive people. Serious allergic reactions like anaphylaxis are rare but have been reported, especially in those with sensitivities.
Can I take this with my antidepressant or birth control?
There are documented interactions with antidepressants (fluoxetine and imipramine) and contraceptive drugs. Don't start this product without checking your specific medications with the interaction tool on this page and confirming with your doctor or pharmacist — they can tell you whether it's safe for you.
Is this a whole anise seed, or processed?
This is a concentrated extract — a 4:1 extract means the plant material was concentrated four times over to make the final product. It's not the whole seed, so the potency is stronger than just using anise as a spice or tea.
