Fei Hong, Liju Wang, Sharon L Wu, Hong Chai Tang, Maria Sm Wai, David Tai Wai Yew
This review looks into the herbs gingko biloba, polygala tenuifolia, and lycii fructus for their widely studied neuroprotective properties. Effects of the interaction between the herbs are studied by behavior tests to evaluate memory, and examination of signal transduction enzyme, major neurotransmitters, cell death and antioxidation. For 6-month treated mice, behavior showed shorter escape latency in the water maze and faster arrival time in a consolidated memory task. Immunochemistry showed evident increase in superoxide dismutase (SOD) activities in the prefrontal cortex, which implies protection against harmful free radicals during aging...

AIM: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common genetic disorder, affecting nearly 400 million individuals worldwide. Whilst it is known that a number of drugs, foods and chemicals can trigger haemolysis in G6PD deficient individuals, the association between herbal and dietary supplements and haemolysis is less clear. The objective of this study was to evaluate the association between herbal or dietary supplements and adverse events in G6PD deficient individuals. METHODS: We searched fourteen electronic databases from their inception until November 2015 for articles describing the use of herbal or dietary supplements in G6PD deficient individuals...

A number of recent trials have demonstrated positive effects of dietary supplementation with the omega-3 polyunsaturated fatty acids (n-3 PUFAs), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) on measures of cognitive function in healthy young and older adults. One potential mechanism by which EPA, and DHA in particular, may exert these effects is via modulation of cerebral hemodynamics. In order to investigate the effects of DHA alone or provided as one component of a multinutrient supplement (also including Gingko biloba, phosphatidylserine and vitamins B₉ and B₁₂) on measures of cerebral hemodynamics and cognitive function, 86 healthy older adults aged 50-70 years who reported subjective memory deficits were recruited to take part in a six month daily dietary supplementation trial...

Tardive dyskinesia (TD) is a serious side effect induced by the long-term administration of typical antipsychotics. The pathophysiology of TD remains unclear, but experimental evidence suggests that neurodegeneration caused by free radicals may play an important role in TD development. S100B is considered a potential biomarker of structural neural and glial damage. This study investigated S100B expression in TD-related brain regions and assessed the effect of antioxidants Gingko biloba leaf extract (EGb761) and vitamin E (VE) on S100B in TD rats...

BACKGROUND: Intermittent claudication (IC) is a symptom of peripheral arterial disease (PAD) and is associated with high morbidity and mortality. Pentoxifylline, one of many drugs used to treat IC, acts by decreasing blood viscosity, improving erythrocyte flexibility and promoting microcirculatory flow and tissue oxygen concentration. Many studies have evaluated the efficacy of pentoxifylline in treating individuals with PAD, but results of these studies are variable. This is an update of a review first published in 2012...

Substances including B vitamins, vitamin D, vitamin E, omega-3 fatty acids and gingko biloba are often consumed in the hope of combating memory complaints and treating dementia. These supplements may seem innocuous, but there is a possibility of drug interactions if they are used in combination with prescription medications. For example, vitamin E and gingko biloba can increase the risk of bleeding and should not be used with anticoagulants.
