The Benefits of Herbal and Black and Green Tea are many. Below is a list that includes just a few of the studies that shows the health and wellness benefits of Tea. In addition, we love hearing about new studies, and hope you will share them with us.


Tea and Health: Studies in Humans


Tea, next to water is the cheapest beverage humans consume. Drinking the beverage tea has been considered a health-promoting habit since ancient times. The modern medicinal research is providing a scientific basis for this belief. 


Green Tea Catechins and Cardiovascular Health: An Update


Extract: Epidemiological data and results from many clinical and experimental studies have shown that green tea consumption may have beneficial effects on cardiovascular health. As major polyphenolic compounds in green tea, catechins may be primarily components in green tea that exert vascular protective effects. Catechins have been shown to inhibit oxidation, vascular inflammation, atherogenesis, and thrombogenesis, and favorably modulate plasma lipid profile and vascular reactivity, suggesting a wide spectrum of beneficial effects of catechins on vascular function


Benefits of Green Tea for Alzheimer’s


Extract: A common beverage may be able to protect you from Alzheimer’s disease and boost brain health. Several studies show that green tea has the potential to protect brain cells, improve memory and delay Alzheimer’s. The affordable and accessible drink has shown promise in research in recent years.


The Effects of Green Tea on Obesity and Type 2 Diabetes


Extract: Various studies have shown the beneficial effects of green tea, not only on cardiovascular diseases but also on obesity and type 2 diabetes itself [6,7]. In a retrospective cohort study performed in Japan, a 33% risk reduction of developing type 2 diabetes was found in subjects consuming six or more cups of green tea daily compared to those consuming less than 1 cup per week


The Protective Effect of Habitual Tea Consumption on Hypertension


Extract: Six hundred subjects (39.8%) were habitual tea drinkers, defined by tea consumption of 120 mL/d or more for at least 1 year. Compared with nonhabitual tea drinkers, the risk of developing hypertension decreased by 46% for those who drank 120 to 599 mL/d…..


Green and black tea consumption and risk of stroke: a meta-analysis


Extract: Although a randomized clinical trial would be necessary to confirm the effect, this meta-analysis suggests that daily consumption of either green or black tea equaling 3 cups per day could prevent the onset of ischemic stroke.


A prospective study of dietary flavonoid intake and incidence of epithelial ovarian cancer.


Extract: These data suggest that dietary intake of certain flavonoids may reduce ovarian cancer risk, although additional prospective studies are needed to further evaluate this association. If confirmed, these results would provide an important target for ovarian cancer prevention.


Tea and Cardiovascular Disease


Exract: There is increasing evidence for a protective effect of tea consumption against cardiovascular disease


Tooth surface pH during drinking of black tea


Extract: The pH and anion profile of black tea are indicative of low acid composition. The very small pH decreases observed at

the tooth surface after drinking tea indicate that it may be safely recommended as a substitute for more acidic drinks as a part of

preventive measures for dental erosion


Black tea benefits: Is Black tea as healthy as green tea?

Extract: According to the Tea Trade Health Research Association regular consumption of simple black tea has been known to reduce the buildup of plaque. Additionally, it has been shown to kill the bacteria associated with many cavities, tooth decay and oral diseases.

Green tea catechins, caffeine and body-weight regulation


Extract: Positive effects on body-weight management have been shown using green tea mixtures. Green tea, by containing both tea catechins and caffeine, may act through inhibition of catechol O-methyl-transferase, and inhibition of phosphodiesterase

Green Tea Study - The University of Maryland


Extract:  Many scientists believe that free radicals contribute to the aging process, as well as the development of a number of health problems, including cancer and heart disease. Antioxidants, such as polyphenols in green tea, can neutralize free radicals and may reduce or even help prevent some of the damage they cause.

Evaluation of anti-inflammatory effects of green tea and black tea: A comparative in vitro study


Extract: From the present findings it can be concluded that both green and black tea leaves possessed a marked anti-inflammatory effect against the denaturation of protein, in vitro. Green tea was found to be more active than black tea, plausibly due to the higher flavonoid contents of green tea.

Antioxidant Capacity of Tea: Effect of Processing and Storage



  • Processing of tea leaves results in profound differences in phenolic compound composition and antioxidant capacity of different types of tea.

  • The more processed the tea, the lower its antioxidant capacity.

  • Antioxidant activity of ready-to-drink tea beverages is much lower in comparison to tea-cup-prepared tea.

  • Extended storage, being necessary to develop desirable taste and aroma of pu-erh and old oolong tea, can lead to loss of quality in white, yellow, green, and black tea.

  • The lower the oxygen permeability of packaging material of ready-to-drink tea, the longer its storage stability.

Honeybush Tea and its positive effects on bone & osteoporosis


Honeybush tea, a sweet tasting caffeine-free tea that is indigenous to South Africa, is rich in bioactive compounds that may have beneficial health effects. 

Honeybush Tea may be a promising in type 2 diabetes management


The different extracts of honeybush tea (particularly the aqueous and ethyl acetate extracts) inhibited lipid and carbohydrate digestive enzymes linked to type 2 diabetes (T2D), as well as modulate oxidative pancreatic injury. These findings will promote its utilization as a potentialThe different extracts of honeybush tea (particularly the aqueous and ethyl acetate extracts) inhibited lipid and carbohydrate digestive enzymes linked to type 2 diabetes (T2D), as well as modulate oxidative pancreatic injury. These findings will promote its utilization as a potential nutraceutical in the management of diabetes and its complications. in the management of diabetes and its complications.

Lavender tea on anxiety and depression 


The prevalence of depression and anxiety is increasing among the elderly around the world. It is believed that lavender can stabilize the people's mood, so this study was designed to evaluate the effect of lavender on anxiety and depression of the elderly. Conclusion: The results of the present study showed that consumption of lavender herbal tea can reduce depression and anxiety scores and since it is inexpensive and accessible, it is suggested to be used as a complementary treatment in reducing anxiety and depression.
