HelloPharmacist Scorecard of Anise Seed & Hyssop Vanilla Flavor by TerraVita

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Anise Seed and Hyssop Glycerite Liquid Extract” is listed as a grouped ingredient — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

This product contains two active ingredients: anise seed glycerite liquid extract and hyssop glycerite liquid extract. Both are delivered as liquid extracts in a glycerin base with vanilla flavoring.

The anise seed is traditionally used for digestive and respiratory symptoms, while hyssop has a history in herbal medicine for cough and sore throat support.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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

The evidence for anise seed is limited. Our data shows insufficient reliable evidence to rate it for migraine headache, lice, menopausal symptoms, premenstrual syndrome, or dysmenorrhea.

One small clinical study suggests anise seed powder may lower fasting blood sugar, but more research is needed. Hyssop similarly lacks established evidence — we have insufficient reliable data on its use for respiratory tract infections, cough, sore throat, urinary tract infections, or dysmenorrhea.

The evidence, ingredient by ingredient Anise Hyssop

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 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Anise seed is generally well tolerated when used as a food or tea. The concentrated essential oil requires more caution.

Orally, anise is well tolerated in most people, though allergic reactions are possible in sensitive individuals — these can range from skin reactions (contact dermatitis) to serious ones like anaphylaxis or occupational asthma. Hyssop in small culinary or tea amounts is likely low-risk, but the essential oil is toxic and can cause seizures.

Hyssop is traditionally thought to stimulate the uterus and should be avoided in pregnancy; there's not enough safety data for breastfeeding either.

Side effects, ingredient by ingredient Anise Hyssop

Meds to double-check

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 2 matched ingredients 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, check with your pharmacist if you're on birth control pills, hormone replacement therapy, blood sugar medications, antidepressants (especially fluoxetine or imipramine), codeine, diazepam, or caffeine supplements. Anise may interfere with or amplify the effects of these medications.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is best suited for someone using it short-term for culinary flavor or light herbal support who isn't on hormone therapy, diabetes medication, antidepressants, codeine, diazepam, or caffeine supplements. If you take any of those medications or are pregnant or breastfeeding, talk with your pharmacist before starting.

The hyssop component has no known drug interactions, but the anise seed does.

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.

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.

Anise Seed & Hyssop Vanilla Flavor by TerraVita: Common Questions

Does Anise Seed & Hyssop Vanilla Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Anise Seed & Hyssop Vanilla Flavor 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 Seed & Hyssop Vanilla Flavor 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.
Can I take this if I'm pregnant?
Anise seed is rated likely safe in pregnancy based on the data we hold. However, hyssop is rated likely unsafe — it's traditionally thought to stimulate the uterus. Since this product contains both, you should talk with your doctor or pharmacist before using it.
Can I take this while breastfeeding?
Anise seed is rated likely safe while breastfeeding. There isn't enough safety information on hyssop during breastfeeding, so it's best avoided. Talk with your pharmacist to see if this product is right for you.
What's the difference between anise and hyssop in this product?
They're two separate herbs with different traditional uses. Anise seed has been used for digestive and respiratory support; hyssop for cough and sore throat. This product combines both as liquid extracts.
Is there reliable evidence this works for cough or sore throat?
Our data shows insufficient reliable evidence to rate hyssop for cough or sore throat, and insufficient evidence for anise seed for any of its traditional uses. More research is needed.
Can anise cause allergic reactions?
Yes. In sensitive individuals, anise can cause contact dermatitis (skin reactions), and rarely, more serious reactions like anaphylaxis, occupational asthma, or rhinitis. If you have a known sensitivity to plants in the celery or carrot family, be cautious.
Is the glycerin base an allergen?
Glycerin is a common inactive ingredient in liquid supplements and is generally well tolerated. If you have specific allergies or sensitivities, check with your pharmacist.
