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

No effectiveness data is on file for this product.

Yew is poisonous and poses severe risk. Swallowed yew can cause nausea, dry mouth, vomiting, dizziness, severe abdominal pain, weakness, nervousness, trembling, shortness of breath, lack of muscle coordination, rapid or slow heartbeat, heart rhythm problems, dangerously low blood pressure, loss of consciousness, coma, seizures, slowed breathing, dilated pupils, and death from cardiac arrest.

Symptoms typically start within 30–90 minutes and can progress to life-threatening heart problems and death within 24 hours. Some people have developed allergies to yew through airborne exposure; those with yew allergy may become hypersensitive to docetaxel, a cancer drug derived from yew.

Yew is unsafe in pregnancy and unsafe while breastfeeding.
