HelloPharmacist Scorecard of Silver Drops by L.A. Naturals

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 Sep 10, 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 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (15 ppm) without saying how much of each component you get.

Silver Drops contains three active ingredients: a proprietary blend, olive, and wild oregano oil, plus inactive ingredients (deionized water, grain alcohol, and non-GMO soy lecithin). The olive and oregano oil are traditional botanical extracts; colloidal silver is a suspension of tiny silver particles in liquid.

The product lists these as a blend without breaking down exact amounts of each component.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Oral bio-protectant and immune system support.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Influenza, Bronchitis, Cough, Rhinosinusitis, Canker sores — and 4 related terms.
  • The closest evidence on file: Colloidal Silver is rated "Possibly Ineffective" for Rhinosinusitis (Natural Medicines).
  • Also on file: Olive is rated "Insufficient Reliable Evidence To Rate" for Influenza.
  • Also on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Upper respiratory tract infection (URTI), Cough, Gingivitis, and more.

The evidence we hold for these ingredients is sparse. Olive has insufficient reliable evidence for osteoporosis, GERD, respiratory infections, shingles, influenza, and osteoarthritis.

Wild oregano oil similarly lacks reliable evidence for acne, bronchitis, asthma, headache, and upper respiratory infections. Colloidal silver is rated possibly ineffective for sinus infections and has insufficient evidence for hay fever and cancer.

No strong evidence supports this product for any of these uses.

The evidence, ingredient by ingredient Olive Colloidal Silver Oregano

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Olive is very safe as a food or oil, but concentrated supplements are less studied — use only with your doctor's approval. Wild oregano oil is fine in food amounts but carries risks in concentrated supplement doses; avoid it in pregnancy, and stick to food amounts while breastfeeding.

Colloidal silver is the main concern: it's not proven effective and can cause serious, sometimes permanent harm with oral use. Health authorities discourage its use.

It should not be taken during pregnancy because silver accumulates in the body and may cause harm, and it should be avoided while breastfeeding because silver may pass to your baby and its safety hasn't been established. Reported adverse effects from colloidal silver include severe anemia, low white blood cell counts, seizures, and bone marrow damage with chronic use.

Side effects, ingredient by ingredient Olive Colloidal Silver Oregano

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 3 matched ingredients can interact with medications — Oregano.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 208 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.

Check with your doctor or pharmacist if you take blood thinners (anticoagulants) or antiplatelet drugs — oregano oil may increase bleeding risk. Also flag diabetes medications — oregano may theoretically increase the risk of low blood sugar.

Colloidal silver itself has no documented drug interactions in our data, but it carries serious safety concerns with oral use that your doctor should know about.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take blood thinners or diabetes medications, talk with your doctor or pharmacist before using this product — the oregano oil in it may affect how these drugs work. Colloidal silver is the bigger red flag: it's not proven to work and carries real safety risks, especially in pregnancy and while breastfeeding.

This is one to discuss with your own healthcare provider before starting.

Yes. Based on its ingredients, Silver Drops has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Silver Drops contains 3 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.
Will this interact with my blood thinner?
The wild oregano oil in this product may theoretically increase bleeding risk when combined with blood thinners or antiplatelet drugs. Talk with your doctor or pharmacist before taking it if you're on any of these medications.
Is colloidal silver safe to take by mouth?
Oral colloidal silver is not proven effective and can cause serious, sometimes permanent harm. Health authorities discourage oral use. Reported effects include severe anemia, low white blood cell counts, seizures, and bone marrow damage with long-term use.
Can I use this while pregnant or breastfeeding?
The colloidal silver in this product should not be used in pregnancy because silver builds up in the body and may cause harm. Avoid it while breastfeeding as well since safety hasn't been established and silver may pass to your baby. Wild oregano oil should be avoided in medicinal amounts during pregnancy, though food amounts are likely fine. Talk with your doctor about safety before use.
What is colloidal silver supposed to do?
According to the evidence we hold, colloidal silver is rated possibly ineffective for sinus infections and has insufficient evidence for hay fever and cancer. It's not proven to work for these uses.
What are the common side effects of wild oregano oil?
Oregano is well tolerated in food amounts. In larger concentrated doses, gastrointestinal upset and skin irritation (topically) are the most common effects. Rare serious reactions include systemic allergic reactions and anaphylaxis in sensitive people.
Does this product contain fillers?
Yes — in addition to the three active ingredients, this liquid contains deionized water, grain alcohol, and non-GMO soy lecithin as inactive ingredients.
