USAGE AND EFFECTIVENESS
| Usage | Effectiveness |
|---|---|
| Low Blood Pressure |
Mild effectiveness (Reduce symptoms of orthostatic hypotension (low blood sugar when standing up from a sitting or lying position)) Several clinical studies showing reduction in symptoms of low blood pressure after standing up; but clinical study is not robust enough (effect of hawthorn alone is unknown); more evidence is needed to support the above |
| Anxiety |
Unclear effectiveness (Improve anxiety) Two clinical studies showing reduction in the symptoms of anxiety when used with other herbs and supplements; but clinical studies are not robust enough (one preliminary clinical study is used, and the effectiveness of hawthorn when used alone is unknown); More evidence is needed |
| Brain Function Deterioration |
Unclear effectiveness (Improve cognitive function) One clinical study to support the above point; but clinical study is not robust enough and it was uncertain if the beneficial effect was due to Hawthorn or other accompanying ingredients; More evidence needed |

| Heart Failure |
Unclear effectiveness (Improve symptoms of congestive heart failure) Several studies showing conflicting results (Older clinical studies show improvement in symptoms of congestive heart failure and reduction in death rate but recent clinical studies show an increased death rate and no improvement in symptoms); more evidence is needed |
| High Blood Pressure |
Unclear effectiveness (Reduce blood pressure) Two clinical studies showing conflicting results (One clinical study showing reduction in blood pressure when a certain hawthorn extract is used while another did not show any significant decrease in blood pressure); more evidence is needed |
