Hawthorn Berry
Also known as: Hawthorn, Crataegus
Hawthorn is a cardiovascular botanical with a long traditional-use history, but modern evidence is limited and safety context is important. This is not a weight-loss ingredient and not a substitute for heart care.
Best Human Use
Best fit as a cautious cardiovascular supplement profile for readers already under appropriate medical care.
Evidence Boundary
NCCIH describes little or no quality evidence for most conditions and conflicting evidence in heart failure.

Source Notes
What It Is
Hawthorn is a flowering shrub or tree in the rose family. Supplements may use berry, leaf, flower, or root material depending on the product. It has a long traditional-use history around the heart and circulation, but modern evidence needs a careful boundary.
Where The Evidence Stands
NCCIH reports little or no quality evidence for most health conditions. Hawthorn has been studied in heart failure, but findings are conflicting. It is not supported as a weight-loss supplement.
Human Utility
This page should keep a reader from treating hawthorn like a casual cardiovascular hack. Chest pain, heart failure, arrhythmia, high blood pressure, and medication changes belong with a clinician.
Product Quality Warning
NCCIH highlights FDA warnings about some supplements labeled as tejocote root or Mexican hawthorn that actually contained yellow oleander, a toxic plant. That makes sourcing and product identity part of the safety discussion.
Safety Boundary
Hawthorn may interact with heart and blood pressure medications. Side effects can include dizziness, nausea, vomiting, diarrhea, and muscle pain. Anyone with cardiovascular disease or related medication use should get medical guidance before using it.
