Polyphenol protection and treatment of hypertension.

Introduction: High blood pressure is the major risk factor for cardiovascular diseases and the rising prevalence of human hypertension precedes the trend toward a global epidemic of unhealthy ageing. A focus on lifestyle and dietary interventions minimizes dependency on pharmacological antihypertensive therapies.

Review: Observational studies indicate that the intake of dietary flavonoids is associated with a decreased risk of cardiovascular disease (CVD).

Danshen diversity defeating dementia.

Salvia miltiorrhiza (danshen) is widely used for the clinical treatment of cerebral ischemia and cardiovascular diseases. Its diverse molecular makeup of simple and poly hydroxycinnamic acids and diterpenoid quinones are also associated with its beneficial health effects such as improved cognitive deficits in mice, protection of neuronal cells, prevention of amyloid fibril formation and preformed amyloid fibril disaggregation related to Alzheimer's disease. Whilst the in vitro studies have therapeutic promise, the anti-dementia effect/impact of danshen however depends on its absorbed constituents and pharmacokinetic properties.
