Herb Pharm Feverfew
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that feverfew is a traditional herbal supplement, but for this specific product, data on its mechanism and efficacy is not available. Our assessment is based on the ingredient data provided, which applies to calcium, not feverfew. For feverfew specifically, there is no data on how it works or its benefits in the provided information.
How it works
For the ingredient calcium, think of it as a structural support for your bones and a calming signal for your muscles and nerves. It supports bone mineralization and density, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. For feverfew itself, data on how it works is not available.
Safety profile
FDA received a total of 592,059 adverse event reports for all supplements, but specific report counts for feverfew are not available. For the ingredient calcium, the data shows that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS].
Our recommendation
Because data on feverfew's benefits and specific side effects is not available from the provided sources, we cannot make a confident recommendation for this supplement. If you are considering it, consult your healthcare provider first, especially since calcium (a common additive) can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Always choose a product with clear labeling and evidence behind its ingredients.
