Despite the lack of English literature about Traditional Chinese Medicine (TCM) food therapy, there is abundant Chinese literature about the application of food therapy for hypertension control. This paper summarizes basic concepts of TCM, the principles of food therapy and its application for hypertension control according to Chinese literature. In TCM, food is conceptualized according to both nutritional and functional aspects, and can be used to treat illnesses. Four principles of TCM food therapy including light eating, balancing the "hot" and "cold" nature of food, the harmony of the five flavors of food, and consistency between dietary intake and different health conditions, can be used to facilitate hypertension control...

Green tea polyphenolic catechins have been shown to prevent various types of diseases such as pulmonary hypertension (PAH), cancer and cardiac and neurological disorders. Matrix metalloproteinases (MMPs) play an important role in the development of PAH. The present study demonstrated that among the four green tea catechins (EGCG, ECG, EC and EGC), EGCG and ECG inhibit pro-/active MMP-9 activities in pulmonary artery smooth muscle cell culture supernatant. Based on the above, we investigated the interactions of pro-/active MMP-9 with the green tea catechins by computational methods...

Reactive oxygen species (ROS) in the brain are involved in the pathogenesis of hypertension. Epigallocatechin-3-O-gallate (EGCG), one of the active compounds in green tea, has anti-oxidant, anti-inflammatory and vascular protective properties. This study was designed to determine whether chronic infusion of EGCG into the hypothalamic paraventricular nucleus (PVN) attenuates ROS and sympathetic activity and delays the progression of hypertension by up-regulating anti-inflammatory cytokines, reducing pro-inflammatory cytokines (PICs) and decreasing nuclear factor-kappa B (NF-κB) activity, as well as restoring the neurotransmitters balance in the PVN of spontaneously hypertensive rats (SHR)...

Neurodegenerative disorders are often life threatening and hired as an economic burden to the health-care system. Nutritional interventions principally involving polyphenols were practiced to arrest or reverse the age-related health disorders. Flavonoids, a class of dietary polyphenols, are rising to superstardom in preventing brain disorders with their potent antioxidant defense mechanism. Quercetin is a ubiquitous flavonoid reported to have all-natural myriad of health benefits. Citrus fruits, apple, onion, parsley, berries, green tea, and red wine comprise the major dietary supplements of quercetin apart from some herbal remedies like Ginkgo biloba...

In premenopausal women, endogenous estrogens are associated with reduced prevalence of arterial hypertension, coronary artery disease, myocardial infarction, and stroke. Clinical trials conducted in the 1990s such as HERS, WHI, and WISDOM have shown that postmenopausal treatment with horse hormone mixtures (so-called conjugated equine estrogens) and synthetic progestins adversely affects female cardiovascular health. Our understanding of rapid (nongenomic) and chronic (genomic) estrogen signaling has since advanced considerably, including identification of a new G protein-coupled estrogen receptor (GPER), which like the "classical" receptors ERα and ERβ is highly abundant in the cardiovascular system...

Endothelial dysfunction is now well established as a pivotal early event in the development of major cardiovascular diseases including hypertension, atherosclerosis, and diabetes. The alteration of the endothelial function is often triggered by an imbalance between the endothelial formation of vasoprotective factors including nitric oxide (NO) and endothelium-dependent hyperpolarization, and an increased level of oxidative stress involving several prooxidant enzymes such as NADPH oxidase and, often also, the appearance of cyclooxygenase-derived vasoconstrictors...

Significant effects on blood pressure (BP) have been reported from large nutritional interventions, particularly the Dietary Approaches to Stop Hypertension (DASH) and the Mediterranean diet. In more recent years, numerous studies have investigated the possible BP-lowering effect of different nutraceuticals; these range from specific foods to minerals, lipids, whole proteins, peptides, amino acids, probiotics, and vitamins. While a very large body of evidence supports the use of potassium, L-arginine, vitamins C and D, cocoa flavonoids, beetroot juice, some probiotics, coenzyme Q10, controlled-release melatonin, aged garlic extract, and coffee, the use of other nutraceuticals, such as green tea, flaxseed, and resveratrol, has not as yet been supported by adequate evidence...

BACKGROUND: Glaucoma is a leading cause of irreversible blindness worldwide. A major symptom of this pathology is the loss to the visual field in a peripheral to central pattern. Flavonoids are polyphenol compounds sourced from plants, commonly found in green tea, red wine and cocoa, and they have neuroprotective and antioxidant characteristics proposed to be advantageous within the context of glaucoma. Currently, the literature presents conflicting evidence regarding the effect of flavonoids on patients with glaucoma and ocular hypertension; hence a systematic review and meta-analysis was conducted...

Obesity and being overweight are linked with a cluster of metabolic and vascular disorders that have been termed the metabolic syndrome. This syndrome promotes the incidence of cardiovascular diseases that are an important public health problem because they represent a major cause of death worldwide. Whereas there is not a universally-accepted set of diagnostic criteria, most expert groups agree that this syndrome is defined by an endothelial dysfunction, an impaired insulin sensitivity and hyperglycemia, dyslipidemia, abdominal obesity and hypertension...

Oxidative stress plays an important role in the pathogenesis of hypertension. Epigallocatechin-3-O-gallate (EGCG) is the main polyphenol present in green tea and is known for its potent antioxidant and anti-inflammatory properties. In the present study, we hypothesize that EGCG attenuates oxidative stress in the paraventricular nucleus of hypothalamus (PVN), thereby decreasing the blood pressure and sympathetic activity in renovascular hypertensive rats. After renovascular hypertension was induced in male Sprague-Dawley rats by the two-kidney one-clip (2K-1C) method, the rats received bilateral PVN infusion of EGCG (20 μg/h) or vehicle via osmotic minipump for 4 weeks...
