Tea polyphenol extracts induced weight loss effects and anti-oxidant activity.
Research, via an animal study, by Heber et al suggests that tea extracts found in Green tea may help with weight loss. A tea rich diet led to significantly lower body weight, total visceral fat volume and liver lipid weight.
It seems that, as well as reducing overall food intake, the extracts are able to induce certain types of gene expression via biochemical changes in the body. This could be great news if you are trying to control your weight in a natural way.
As ageing populations grow, diseases such as Rheumatoid arthritis are becoming more prevelant. With advancing years this disease can lead to massive bone destruction with inflammation and pain. The researchers (Al-Nahain et al) in this recent paper study and review ginger (Zingiber official). This spice has traditionally been used for treatment of Rheumatoid arthritis in many countries like India where Ayurvedic doctore have been using it for many hundreds of years.
This review attempts to list the constituents and mechanisms of action.
The study concludes that phytochemicals from Ginger can form the basis of discovery of new drugs, which not only can provide symptomatic relief but also may provide total relief from diseases like Rheumatoid arthritis inhibiting bone destruction.
A stroke can cause chronic disability and death in patients. This review by Navabi et al researched recent research on the neuroprotecitve agents for stroke with emphasis on Camellia sinensis L. (tea or Green Tea). Tea is the second most consumed beverage worldwide, after water.
Catechins, a type of polyphenol, are the main phytochemical constituents of tea and these compounds have high antioxidant capacity.
Their review show that there is significant research that supports the protective effects of tea consumption against ischemic stroke.

“Alzheimer’s disease (AD) is the most prevalent neurodegenerative disease in the growing population of elderly people. A hallmark of AD is the accumulation of plaques in the brain of AD patients. The plaques predominantly consist of aggregates of amyloid-beta (Abeta), a peptide of 39-42 amino acids generated in vivo by specific, proteolytic cleavage of the amyloid precursor protein.” (Finder & Glockshuber)
Stefani & Rigacci review the evidence for polyphenols and their ability to reduce amyloid aggregation. Natural polyphenols are emerging as an increasingly attractive treatment for amyloid disease prevention and therapy. Evidence suggests that they can inhibit the production of amyloidogenic peptides, increase antioxidant enzyme activity and reduce inflammation. The researchers suggest that we should now be describing them as potentially multitargeting drugs.
Potential sources of polyphenols are found in, amongst others, vegetables, fruit and green tea.
Holy basil – (Ocimum sanctum or Tulsi) has been used in traditional medicines like Ayurveda to treat cardiovascular diseases (CVD) and manage heart health.
A study by Choudhury et al analyses the antiinflammatory effect of Holy Basil (Ocimum sanctum) and its constituents for treating cardiovascular diseases.
Good news for infusion drinkers!
It is that time of year in the northern hemisphere when thoughts turn to staying in shape or at least thinking about weight control.
