HelloPharmacist Scorecard of Find Strength by Nature's Sunshine Flower Essence Formula

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

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 8 active ingredients.
  • “purified Water” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.
  • “Infusions of the Flowers of” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

This liquid formula contains 8 ingredients, including vegetable glycerin as a base and an infusion of flower essences. The active botanical ingredients we can identify are centaury (a traditional digestive herb), yarrow (used historically for various wellness purposes), and California goldenrod.

The product also contains three other flower infusions we don't have detailed data for: Calochortus leichtlinii, Pinus sylvestris, Mimulus cardinalis, and Fuchsia magellanica.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: emotional strength and occasional stress support.
  • We looked for evidence on: emotional resilience, stress management, anxiety, mood support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence on these botanicals is limited. Glycerol (the vegetable glycerin base) is rated likely effective for constipation and possibly effective for athletic performance, but that's not the main purpose of this formula.

For the flower essences themselves — centaury, yarrow, goldenrod, and the others — we don't hold effectiveness data in our records. The evidence for their wellness claims isn't established in the information available to us.

The evidence, ingredient by ingredient Glycerol

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 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.

Glycerol is generally well tolerated in normal amounts, though large doses can cause bloating, nausea, diarrhea, dizziness, and headache. Yarrow, taken orally, seems well tolerated, but topical contact can cause allergic or irritant dermatitis, and handling the flowers has rarely triggered respiratory symptoms.

Yarrow should not be used in pregnancy because it may affect the uterus, and safety while breastfeeding isn't known. Centaury is traditionally used in small amounts as a digestive bitter, but high-quality safety data are limited; it should be avoided in pregnancy and while breastfeeding.

For the other flower ingredients, we have no specific safety data on file.

Side effects, ingredient by ingredient Glycerol

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 — 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, talk to your doctor or pharmacist before using this product — yarrow may raise lithium levels and side effects, and your dose might need adjustment. We could not check the interaction potential of several of the flower ingredients in this blend, so run your complete medication list through our search tool before you start.

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 is a flower essence blend that may appeal to you if you're drawn to traditional botanical formulas. If you take lithium or any other prescription medications, check with your doctor or pharmacist before starting — the yarrow content may affect lithium levels.

Avoid it in pregnancy and while breastfeeding, or talk with your healthcare provider about whether it's right for you.

Find Strength by Nature's Sunshine Flower Essence Formula: Common Questions

Does Find Strength by Nature's Sunshine Flower Essence Formula interact with any medications?
Yes. Based on its ingredients, Find Strength 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?
Find Strength contains 2 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.
Can I take this if I'm pregnant or breastfeeding?
No. Yarrow should not be used in pregnancy because it may affect the uterus, and centaury is also best avoided because safety data are too limited. Safety while breastfeeding is unknown for both yarrow and centaury. Talk with your doctor or pharmacist about whether this product is right for you.
What does yarrow do in this formula?
Yarrow has been used traditionally for various wellness purposes, though we don't have effectiveness evidence for a specific claim in our data. It's included as part of the flower essence blend, and it is the ingredient in this product that interacts with lithium.
Is vegetable glycerin safe to take by mouth?
Yes, generally. Glycerol is well tolerated in normal amounts. Large doses can cause bloating, nausea, diarrhea, dizziness, and headache — but this formula contains it as a base ingredient in a modest amount, not as a medicinal dose.
Will this help with [specific condition]?
We don't have effectiveness evidence on file for the flower essences in this formula. If you're considering it for a specific health concern, talk with your doctor or pharmacist to see whether it makes sense for you.
What are the side effects I might notice?
Taken orally, yarrow is generally well tolerated. Glycerol can occasionally cause bloating, nausea, diarrhea, dizziness, or headache if large amounts are taken. Allergic reactions are possible with any botanical ingredient, though they are uncommon.
Do I need to avoid this with any vitamins or supplements?
We don't have documented interactions with vitamins or other supplements. However, if you take lithium or any prescription medication, check with your pharmacist or doctor before adding this product to your routine.
