Oolong Tea: Lower Cholesterol And A Warfarin Warning
Crushed tea leaves that have been oxidized for a period of time, and then heated to stop the process, make up Oolong tea, says Brill. One clinical study on Oolong tea found that it may help lower cholesterol levels in patients with coronary artery disease, though more research is needed to be certain. In animal studies, Oolong appeared to reduce triglycerides and food intake, says Dr. Day, though he adds that there is not yet a lot of data on Oolong and its cardiac effects.
Day advises talking to your doctor if you plan to drink Oolong, especially if you take a blood thinner like Coumadin. must tell their doctors everything they are taking every herb, supplement, vitamin, and so on. And that includes tea.

How Matcha Can Help
Our beloved green tea comes with the healthy lifestyle parts of preventive measures for heart disease.
Its nutrients can help supplement a balanced diet, a good mood, a peaceful mental state, and it can even help in weight loss for obese people.
This fact comes from the way matcha is produced. While regular green tea leaves are sun-grown, picked, dried, and tea-bagged, matcha is shade-grown, dried, and ground into finely powdered matcha.
This unique treatment significantly multiplies the antioxidant, amino acid, and caffeine content of matcha.
It also has concentrated amounts of vitamins and minerals, and it is high in fiber and chlorophyllin.
This nutritious powder contains things that can help you prevent heart disease. While it is not a medicine, you can consider it a highly-valuable supplement that can help you fight away morbid illnesses.

How To Brew Matcha Green Tea
Though Matcha can cost $4 or more in a cafe, you can make it inexpensively at home. We enjoy Matcha as a treat about once a week, and Ive also enjoyed experimenting with adding it to foods for color. Though in Japan, a tea ceremony is an elaborate practice that involves special cups, tea pots and bowls, there is a simplified process that you can use at home.
There are two ways to brew, as usucha or koicha. Usucha is a thin tea, while koicha is a thicker tea.
- A bamboo whisk and spoon TIP: in a pinch, use a blender.
- Fine mesh strainer or sifter
- A glass bowl for whisking
- Small cups for drinking tea

Molecular Mechanisms Of Tea Regulating Blood Pressure
It is well known that sympathetic nerve activity plays a pivotal role in blood pressure regulation. Tanida et al. reported the effects of oolong tea on renal sympathetic nerve activity and spontaneous hypertension in SHR rats. They found that intraduodenal injection of OT in urethane-anesthetized rats suppressed RSNA and decreased blood pressure. In addition, pretreatment with the histaminergic H3-receptor-antagonist thioperamide or bilateral subdiaphragmatic vagotomy eliminated the effects of OT on RSNA and blood pressure. Furthermore, drinking OT for 14 weeks reduced blood pressure elevation in SHR rats. These results suggest that OT may exert its hypotensive action through changes in autonomic neurotransmission via an afferent neural mechanism. The authors also found that intraduodenal injections of decaffeinated OT lowered RSNA and blood pressure to the same degree as caffeinated OT, indicating that substances other than caffeine may function as effective modulators of RSNA and blood pressure. Han et al. provided additional evidence that EGCG counteracts caffeine-induced increases in arterial pressure, adrenaline and noradrenaline levels in the blood, and heart rate. The authors suggested that EGCG may exhibit these properties by decreasing the levels of catecholamines in the blood.
The underlying mechanisms of tea regulating blood pressure using cell culture and animal models are illustrated in the .
Small Changes Can Make A Big Difference In Your Blood Pressure Numbers
If you suddenly find yourself with high blood pressure under the new guidelines from the American Heart Association and the American College of Cardiology, you might be wondering what to do. The guidelines lowered the definition for high blood pressure to 130/80 from 140/90 millimeters of mercury , meaning more people now meet the criteria for stage 1 hypertension.
While you shouldnt shrug off the change, theres also no need to panic. Obviously, nothing happened overnight inside a womans body or to her health with the release of the guidelines, says Dr. Naomi Fisher, director of hypertension service and hypertension innovation at the Brigham and Womens Hospital Division of Endocrinology, Diabetes, and Hypertension, and associate professor of medicine at Harvard Medical School.
The change, however, should spur you to take your blood pressure seriously. These guidelines have been long anticipated and are very welcome by most hypertension experts. They may seem drastic, but in putting the knowledge weve gained from large trials into clinical practice, they will help thousands of people, says Dr. Fisher.

What Is The Best Tea For High Blood Pressure
The use of teas for the treatment of high blood pressure is one of the best natural ways of treating such a condition.
You can imagine enjoying the great tastes of natural tea and at the same time managing your blood pressure effectively.
Most research indicates and supports that green tea has stronger antioxidants properties than black tea, but some studies found that both teas exhibit equally effective antioxidant capacities.
Some say patients with high blood pressure always feel like they are a step away from death, but that is not true! Hypertension, like so many other ailments, can be treated and managed, can be supported naturally by the intake of tea from the natural plant Camellia sinesis.
Teas are of many types like Green tea, Black tea, Oolong tea, Puerh tea and White tea.
All these teas were classified based on the type of leaves picked and the processes or oxidation level.
Surprisingly all these types of teas are extracts of the same basic plant, the Camellia sinesis and they are believed to be effective agents in the treatment of high blood pressure.
Black tea and Green tea are recorded as the most consumed and sort after teas in the western world.
NB: No tea has been named or selected as the best for treatment for hypertension, though.
To explain better how tea drinking effects on hypertension better, best to revisit the disease to understand it better.
Data Synthesis And Analysis
Net changes in each of the study variables, calculated from baseline and follow-up means and standard deviations , were used to estimate the principle effect. When the standard deviations were not available directly, they were calculated from standard errors or CI. If variances for net changes were not reported directly, they were calculated from CI, P values, or individual variances from the tea group and the control group. For trials in which variances for paired differences were reported separately for each group, we calculated a pooled variance for net changes using standard methods. Missing variances for paired differences were calculated from variances at baseline and at the end of the follow-up for each measure using correlation coefficient methods according to the Cochrane Handbook for Systematic Reviews of Interventions. We assumed a correlation coefficient of 0·62.

Cinnamon And Cardamom Tea
Cinnamon and cardamom are tasty seasonings that can also provide us with some significant health benefits.
Their effect on blood pressure has not been researched extensively, but there is some evidence that they might be useful in treating it.
Research Results on Cinnamon and Cardamom
A small-scale study conducted in India had 20 hypertensive individuals consume cardamom powder for 12 weeks. A significant reduction in systolic and diastolic blood pressure was observed after the treatment.
Another study related to cinnamon found that it effectively decreased the blood pressure of people with type 2 diabetes.
Interventional Trials For Diabetic Populations
High blood pressure is more common in people with diabetes. It was estimated that two-thirds of patients with type 2 diabetes have high blood pressure . Mozaffari et al. conducted a randomized clinical trial in which 100 mildly hypertensive patients with diabetes were randomly assigned into a green tea treatment group. The patients were instructed to drink green tea infusion three times a day, 2 h after each meal for four weeks. Blood pressure was measured at days one and 15, and at the end of the study. The results showed that the SBP of the green tea group was lower at the end of the study . The DBP was also lower by the end of the study . The therapeutic effectiveness of tea by the end of the intervention was 39.6% in the green tea group. This data indicates that mildly hypertensive type 2 diabetic individuals who drink green tea daily show significantly lower SBP and DBP. Another study was conducted in Japan with 60 volunteers who had fasting blood glucose levels of 6.1 mmol/L or non-fasting blood glucose levels of 7.8 mmol/L. The intervention group consumed a packet of GTE containing 544 mg polyphenols daily for the first two months, and then entered a two-month nonintervention period. Supplementation of GTE powder led to a significant reduction in DBP, but no significant changes in SBP.

Interventional Trials For Obese And/or Hypertensive Populations
Black tea accounts for 78% of the worlds tea production and is consumed worldwide. Therefore, it is important to determine whether black tea has an anti-hypertension effect. Grassi et al. investigated the effect of black tea on blood pressure and vessel wave reflections before and after fat consumption in hypertensive patients. In a randomized, double-blind, controlled, cross-over study, 19 patients were assigned to consume black tea or a placebo twice a day for eight days . Digital volume pulse and BP were measured before and 1, 2, 3 and 4 h after tea consumption. Measurements were performed in a fasted state and after a fat load. The authors found that fat consumption led to increase wave reflection, which was counteracted by tea. The results indicate that black tea consumption decreases SBP and DBP by 3.2 mmHg and 2.6 mmHg, respectively, and prevented blood pressure increase after a fat consumption. These findings indicate that regular consumption of black tea may play an important role in cardiovascular protection.
What Kind Of Tea Is Good For High Blood Pressure
It is the most widely consumed drink, after water. There are many different types of tea available, like Darjeeling and Chinese teas which have a cooling, slightly bitter, and astringent flavor, and some which have vastly different profiles that include floral, nutty, sweet, or grassy notes. AAlso, then there are types which are best known for their benefits like lowering high blood pressure.

Black Teafor Blood Pressure
There are many different blends and types of black tea available. Studies have found that black tea could be effective when controlling blood pressure because of the oxidation of leaves. Flavones, a variety of plant pigment with antioxidant properties, is also considered the reason behind its magical properties. It has also shown positive effects on endothelial cells, which are responsible for early blood pressure changes. It also controls weight and BMI, which are essential factors that contribute to blood pressure.
Limit Your Alcohol Intake
Regularly drinking too much alcohol can raise your blood pressure over time.
Staying within the recommended levels is the best way to reduce your risk of developing high blood pressure:
- men and women are advised not to regularly drink more than 14 units a week
- spread your drinking over 3 days or more if you drink as much as 14 units a week

Caffeine And Blood Pressure
Caffeine is a bitter substance found naturally in tea leaves and other plants. The Food and Drug Administration has recommended that healthy adults drink no more than 400 milligrams of caffeine each day. Regular tea can contain 14 to 60 milligrams of caffeine per 8 ounces, notes the U.S. National Library of Medicine. Small traces of caffeine will still be found in tea that is considered caffeine free, just less than their regular counterparts.
Caffeine has many effects on the body, such as stimulating your central nervous system so you feel energetic and awake. It may also increase your blood pressure temporarily, especially one hour after consumption, when it’s at peak level in the blood. The reason behind the brief rise in blood pressure is still unclear, and some people may be more sensitive to caffeine effects than others, according to the Mayo Clinic.
If you already deal with high blood pressure, it’s best to consult your doctor on whether you should limit or stop drinking caffeinated beverages. It’s also important to avoid drinking large amounts of caffeine before participating in activities that naturally raise your blood pressure, such as exercising or physical labor, says Mayo Clinic.

Green Tea Might Help Fight Off Cancer
Your cells naturally accumulate oxidative damage during regular cell metabolism. A class of molecules called antioxidants can prevent or even reverse that damage. One of the most powerful antioxidants is called epigallocatechin gallate, and it is found in high levels in green tea. Epigallocatechin gallate has been shown to reduce the growth of breast and prostate tumors .
St John’s Wort: Risky Combined With Heart Meds
You may have heard that the St. Johns Wort herb can help treat symptoms of depression, but be wary of drinking this tea if you have a heart condition. My biggest concern is that its not good with cardiac medications, says Steinbaum. She says the ingredient is “epically dangerous” if youre taking blood thinners or cardiac medications for heart failure, like digoxin, or if you require a stent or have atrial fibrillation.
If you’re considering drinking St. Johns Wort tea for depression, talk to your doctor instead, Steinbaum says. Theres such a close association between depression and heart disease. Its the kind of thing I wouldnt want anyone to treat on their own.
