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

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: hydrangea extract powder in a 4:1 concentration, meaning it's a condensed form of the hydrangea plant. The product has no inactive ingredients listed.

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 Hydrangea product and its label doesn't state a use — see Hydrangea'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.

We hold no effectiveness ratings for hydrangea extract in our data, so we cannot tell you what conditions or symptoms it may or may not help with based on published evidence.

The evidence, ingredient by ingredient Hydrangea

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.

Hydrangea has limited safety information in humans. Taking large doses or using it for a long time may cause unwanted effects.

The plant may cause gastroenteritis (stomach upset), dizziness, or a feeling of tightness in the chest when taken by mouth. The safety data advises against use during pregnancy.

There is no reliable safety information for breastfeeding, so it's best avoided if you're nursing. If you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist before using this product.

Side effects, ingredient by ingredient Hydrangea

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 1 matched ingredient can interact with medications — Hydrangea.
  • 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, double-check with your pharmacist before starting this product—hydrangea may increase lithium levels in your blood.

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.

This is a single-ingredient hydrangea extract. If you take lithium for a mood disorder, you'll need to check with your doctor or pharmacist before starting—the diuretic effect may raise lithium levels.

For anyone else, the main concern is that human safety data are sparse, especially for longer use.
