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 don't have effectiveness data on file for hydrangea in this product.

  • 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 is generally well tolerated, but human safety data are limited and large or prolonged doses may cause unwanted effects. You may experience gastroenteritis (stomach and bowel irritation), dizziness, or a feeling of tightness in the chest.
