Effects On Growth Factor
Epidermal growth factor is a general growth factor with action not only on epithelial cells but also on a large variety of other cells, accounting for disparate cellular activities such as proliferation, angiogenesis, survival, differentiation, migration, and apoptosis . Today, it has been established that there is an epidermal growth factor receptor tyrosine kinase family, which is currently extensively studied for its role in human development, physiology, and cancer . EGCG and other GTPs have been shown to interact with epidermal growth factor-associated signaling by inhibiting EGFR autophosphorylation in carcinoma cells . Moreover, EGCG can inhibit cell transformation by directly interacting with cellular target proteins such as the SH2 domain of Fyn tyrosine kinases . Targeted disruption of the EGF receptor has been shown to block the development of papillomas and carcinomas from human papillomavirus-immortalized keratinocytes , which could in part account for the chemopreventive and antipapillomatous activity of topically applied EGCG.
EGCG has also been shown to block other growth factors such as platelet derived growth factor , fibroblast growth factor , vascular endothelial growth factor , and insulin-like growth factors . Interactions of EGCG with growth factor-associated signaling have been shown to be in part due to the inhibition of intracellular signaling cascades but also due to trapping of growth factors by EGCG .
May Lower The Risk Of Insulin Resistance
Insulin is an incredibly important hormone. It helps move nutrients from the bloodstream into the cells to be used or stored for later.
However, as a result of several factors, including high sugar consumption, some people stop responding to insulin. This is called insulin resistance.
Sadly, insulin resistance is very common and is linked to many chronic health conditions, including type 2 diabetes, heart disease and metabolic syndrome .
Interestingly, studies have found that polyphenols like the ones in white tea may lower your risk of insulin resistance .
Animal studies have found that EGCG and other polyphenols found in white tea may enhance the effects of insulin and prevent high blood sugar levels .
In an analysis of 17 studies with over 1,100 people, scientists found that the molecules inside teas, like polyphenols, significantly reduced blood sugar and insulin levels .
While the research seems promising, more human-based studies specifically on white tea will help clarify whether it can reduce the risk of insulin resistance.
Summary Insulin resistance is a harmful condition linked to many chronic diseases. Studies have shown that polyphenols like those found in white tea may lower the risk of insulin resistance and improve blood sugar control.

What We Drink Every Morning
To be clear, the potential health benefits of hibiscus tea remain unproven. There is not enough human research for any of them to be classified as proven. For that reason, you should NOT drink it with the intention to prevent, cure, or treat any disease. Its not a medicine. It should be consumed as a food or dietary supplement only.
As far as it possibly being bad for you, there isnt proof of that, or even research hinting that it might be unhealthy. Its zero calories and tastes delicious if you sweeten it with this zero calorie monk fruit.
With that added, it kind of tastes like Kool-Aid and we say that as a compliment, not a criticism! Because unlike that disastrous drink you had as a child, this is something guilt-free and good for you. Sip on it in the morning, afternoon, and into the evening, too. Its a 100% caffeine-free herbal tea.
Served as a cold tea, agua de flor de Jamaica is popular in Mexico, Central, and South America. In Australia they called it rosella.
In the United States, Canada, and United Kingdom, unfortunately its a very hard to find beverage. Practically no one sells if pre-brewed. You wont find this healthy tea at Starbucks. Even the tea bags are hard to get your hands on. You probably wont see them at Walmart, Target, or a traditional grocery store. At least we never have here in Los Angeles.
Even if we did see it for sale, we probably wouldnt buy it.
Why? Because we prefer a blend instead
Increasing The Antioxidants In Our Bodies
The plant worldprovides us a rich smorgasbord of antioxidants with the polyphenols theycontain. Tea is one rich source. Other foods with an abundance of polyphenolsinclude berries, grapes/wine, olive oil, cocoa, coffee, nuts, legumes, fruits,and vegetables.

What Are Antioxidants In Tea
One of the most popularly consumed beverages in the world, tea is not just the most loved drink, but also considered one of the healthiest! With lower caffeine content than coffee, it was already in the running for the better health drink. But its the presence of significant antioxidant levels, that has sealed teas reputation for health. To understand antioxidants, we must first get acquainted with free radicals.
What are free radicals?
Free radicals are what are formed when weak chemical bonds split. As molecules, free radicals are unstable and seek stability by adding an electron. It does this by attaching a stable molecule, rendering it unstable in return. Consequently, there is a cascading effect which has damaging effects on the cell. Free radicals are produced during metabolism but their function is to work as part of the bodys immune system. Their unfavorable reputation comes from the fact that environmental pollutants, radiation and so on also proliferate free radical production.
While the body can respond to normal levels of free radicals, in excess it needs the support of antioxidants.
How do antioxidants combat them?
Antioxidants in tea
All tea comes from the same plant, Camellia sinensis. Differences in processing yield the various tea types ranging from the most processed black tea to oolong tea, green tea and the least processed white tea. The antioxidants present in tea are known as flavanoids.

Black Tea May Promote Healthy Cognition And Reduce Inflammation
Green tea gets most of the hype for its potentially health-boosting properties, but black tea appears to offer plenty of health benefits, too.
Retelny notes that scientific evidence suggests black tea may play a role in preventing cognitive decline, inflammation, heart disease, diabetes, and potentially cancer.
One study published in January 2016 in The Journal of Nutrition, Health & Aging found that regularly drinking black tea was associated with a lower risk of developing a neurocognitive disorder, such as dementia, in the elderly, particularly for elderly women.
If you are looking to fend off type 2 diabetes and dont care for green tea, the black variety could be an effective alternative, suggests one review.
Black tea also contains flavonoids , which may help lower cancer risk. A study published in August 2019 in the journal Nature Communications shows that a diet rich in flavonoids may help protect against cancer and heart disease.
What Is Camellia Sinensis
Camellia sinensis is a small tree whose leaves and leaf buds are used to make tea. Almost every non-herbal tea enjoyed today comes from this specific species of plant, including black, green, and white tea.
Although black, green, and white tea come from the same plant, the only difference between them is how theyre processed.

Ex Vivo Ldl Oxidation
It has been suggested that susceptibility of LDL to oxidation plays an important role in atherogenesis. In vitro studies have consistently demonstrated that tea flavonoids can inhibit the oxidation of LDL , which has been taken as an indication that tea consumption may reduce the risk of coronary artery disease. Also, several epidemiological studies indicate that consumption of black tea in realistic amounts is associated with decreased risk of coronary artery disease . However, the studies in humans summarized here have not provided sufficient support for such a function in vivo.
Determination Of Antioxidant Capacity Using Epr Method Based On A New Semi
Trolox equivalent antioxidant capacity was determined using an EPR method based on a new semi-empirical mathematical model described previously . The mathematical model was based on three variables: x = V, y = %I, and z = I100, where Vis the volume of antioxidant added to the DPPH free-radical solution , %Iis the inhibition of the EPR signal of the DPPH free-radical, I100is the value calculated from the Eq. describing the relationship between %I and V corresponding to a 100 mL sample.
where a0 = f0g0, a1 = f0g1, a2 = f0g2, a3 = f0g3, a4 = f1g0, a5 = f1g1, a6 = f1g2, a7 = f2g0, a8 = f2g1, a9 = f3g0 .

Can Tea Improve Heart Health
All three green, white, and black tea contain some overlapping and some different polyphenols in varying amounts that have numerous benefits to human health. These benefits include modulating the microbiome, helping with hormonal balance, and improving heart health.
Polyphenols are believed to benefit heart health in multiple ways, one being by preventing LDL or bad cholesterol from oxidizing, which is a risk factor for heart disease.
They have also been shown to act as antioxidants and combat the negative effects of oxidative stress or inflammation in the body, which has been linked to a wide variety of diseases including heart disease.
We also have research showing that tea consumption may reduce the risk of high blood cholesterol concentrations and high blood pressure. Studies have also shown that these polyphenols have a preventative effect against atherosclerosis.
Atherosclerosis is a disease in which plaque, cholesterol, and other material deposits in and on the artery walls. This is problematic as it causes constriction of blood flow and can lead to heart attack or stroke. Atherosclerosis is even the underlying cause of about 50% of deaths in westernized societies.
