HelloPharmacist Scorecard of Yew/Olive Combination by New Sun

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 11, 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 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (800 mg) without saying how much of each component you get.

This product contains 4 ingredients: a proprietary blend, olive, yarrow, and Pacific yew, plus olive concentrate. The blend is a combination formula, so the exact amounts of each aren't disclosed separately.

Olive and its concentrated form appear twice in the ingredient list — they're the same plant source provided in different preparations. Olive (including its concentrate) and yarrow are the established herbal components here.

Pacific yew is also included, though we don't have detailed monograph information on it. The capsule itself is vegetarian.

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 we hold on these ingredients is limited. Olive and olive concentrate are listed for six uses — osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles (herpes zoster), influenza, and osteoarthritis — but all are rated insufficient reliable evidence to rate.

Yarrow carries the same rating across six conditions: tonsillitis, wound healing, eczema (atopic dermatitis), menstrual pain (dysmenorrhea), and vaginal yeast infection. We don't have effectiveness data on file for Pacific Yew.

The evidence, ingredient by ingredient Olive Yarrow

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 2 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.

Olive and olive concentrate are well tolerated in typical food amounts and as extracts in most users. The most common side effects are headache and stomach discomfort; a small number of trial participants reported skin issues or acne.

Olive tree pollen can trigger seasonal allergies if you're sensitive. Yarrow's safety data are more limited.

When taken by mouth or applied vaginally, it's generally well tolerated, but topical use can cause contact dermatitis (allergic skin inflammation) or hives, especially in people with allergies — it contains compounds that can also trigger sun-related skin reactions and airborne contact reactions. Yarrow is traditionally avoided in pregnancy because it may affect the uterus, and there isn't enough safety data to recommend it while breastfeeding.

Pacific Yew's safety profile isn't on file here.

Side effects, ingredient by ingredient Olive Yarrow

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 — Yarrow.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 1 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.

If you take lithium, you must check with your pharmacist before using this product — yarrow may increase lithium levels and side effects (Moderate severity). No interactions are documented for the other ingredients we could check, though we were unable to verify Pacific Yew.

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.

If you take lithium, check with your pharmacist before using this product — yarrow may affect your lithium levels. Olive is well tolerated, but concentrated olive supplements are less studied than olive oil and whole olives as food.

Yarrow can cause skin reactions in sensitive people and should be avoided in pregnancy and breastfeeding. Your pharmacist can help you decide if this combination is right for you.

Animal research shows that yarrow has diuretic activity. Theoretically, due to these potential diuretic effects, yarrow might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Yes. Based on its ingredients, Yew/Olive Combination has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Yew/Olive Combination contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 to take while I'm pregnant?
Yarrow, one of the active ingredients, is traditionally avoided in pregnancy because it may affect the uterus. We don't have safety information on file for Pacific Yew in pregnancy. Talk with your doctor or pharmacist before using this product — it's a decision we can't make for you without knowing your full medical picture.
What side effects should I watch for?
Olive and olive concentrate most commonly cause headache or stomach discomfort. Yarrow can trigger contact dermatitis (allergic skin inflammation) or hives, especially in people prone to allergies, and can cause reactions to sun exposure. Some people may develop acne. If you have a history of skin sensitivity, let your pharmacist know.
Can I take this while breastfeeding?
There isn't enough safety data to recommend yarrow while breastfeeding, so it's best avoided. We don't have pregnancy and lactation information on file for Pacific Yew or Olive. Talk with your pharmacist or doctor before using this product.
What's in this product — is it mostly filler?
The product contains four active ingredients — olive, yarrow, Pacific yew, and a proprietary blend — plus a vegetarian capsule. The proprietary blend means the exact breakdown of amounts isn't disclosed on the label, but there are no other inactive fillers listed.
Does olive in this product actually work?
The evidence on olive for the six uses listed here — osteoporosis, indigestion, respiratory infections from exercise, shingles, influenza, and arthritis — isn't reliable enough for us to rate. More research is needed to know whether it's effective for these conditions.
I'm allergic to pollen. Should I avoid this?
Olive tree pollen can trigger seasonal respiratory allergies in sensitive people. If you have a pollen allergy, especially to olive, mention it to your pharmacist before using this product.
