Hibiscus Tea Is Found to Lower Blood Pressure
Family Practice News ^ | 1 January 2009 | BRUCE JANCIN

NEW ORLEANS — Quaffing three cups of hibiscus tea daily for 6 weeks resulted in a mean 7.2-mm Hg reduction in systolic blood pressure in mildly hypertensive or prehypertensive adults in a randomized, double-blind placebo-controlled trial.

“This suggests that regularly incorporating hibiscus tea into the diet may help control blood pressure in people at risk of developing hypertension,” Diane L. McKay, Ph.D., said at the annual scientific sessions of the American Heart Association.

The public health implications of a blood pressure reduction of this magnitude, if extended to a large population, could be profound. According to the National High Blood Pressure Education Program Coordinating Committee, a mere 3-mm Hg reduction in systolic blood pressure (SBP) would reduce the relative risk of death due to stroke by 8%, due to coronary artery disease by 5%, and all-cause mortality by 4% (JAMA 2002;288: 1882-8), said Dr. McKay, of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, Boston.

She reported on 65 prehypertensive or mildly hypertensive adults who took part in a 6-week double-blind study in which they consumed three 8-ounce cups of hibiscus tea daily or a placebo beverage similar in color and taste.

Mean SBP dropped by 7.2 mm Hg in the herbal tea group from a baseline of 129.4 mm Hg, compared with a 1.3-mm Hg decline in the control group. Diastolic blood pressure (DBP) fell by a mean of 3.1 mm Hg from a baseline of 78. 9 mm Hg and mean arterial pressure dropped by 4.5 mm Hg from 95.7 mm Hg at enrollment, although neither of these changes achieved statistical significance.

However, the tea's antihypertensive effect increased with higher baseline blood pressure. In the half of subjects whose SBP exceeded 129 mm Hg, mean SBP reduction after 6 weeks of hibiscus tea consumption was 13.2 mm Hg, and the reductions of 6.4 mm Hg in DBP and 8.7 mm Hg in mean arterial pressure were also statistically significant.

The intervention had no side effects or downsides, said Dr. McKay.

Dr. Robert H. Eckel observed that the blood pressure reduction seen with hibiscus tea in this trial is equal to the typical effect of a single antihypertensive medication.

But although the notion of the tea as a nutraceutical for blood pressure lowering is intriguing, a larger confirmatory study with longer follow-up is needed, said Dr. Eckel, past president of the AHA and professor of medicine, physiology, and biophysics, and program director of the adult general clinical research center at the University of Colorado, Denver.

Dr. McKay and coworkers conducted their randomized trial because earlier animal studies suggested Hibiscus sabdariffa L. has antihypertensive and antiatherosclerotic effects. Hibiscus contains flavinoids and phenolic acids which have potent antioxidant properties. The study was supported by the Agricultural Research Service of the U.S. Department of Agriculture and by Celestial Seasonings.

I use hibiscus in herb formulas - it’s tasty when sweetened, it comes in powder form which I use, also the whole flower and cut and sifted pieces. It is a tropical flower, not the pretty kind you see in Hawaii, it’s a smaller variety. It makes a beautiful ruby color tea which can also be drunk cool in the summer.

It is very refrigerant - cooling for summer or fevers or just hot symptoms, good for mental “cooling” as well, infections, over heated blood (a CHinese and Ayurvedic description), good for other organs and systems such as the liver and female system.

It goes very well with some fruit juices such as adding a bit of lemon or lime juice. It’s much cheaper to buy it in bulk by the pound.

Should have added - I don’t have high blood pressure so I can’t comment on that part. But I hate the heat and do drink it a lot in the summer and it definitely helps to cool the body. It also works well combined with peppermint. Hibiscus has a pleasantly fruity sour taste, I prefer it sweetened.

This is purely empirical, anecdotal evidence, so take it FWIW, but after a year of trying to get my wife’s BP back to normal levels, guess what seemed to do it?

Fish oil, and vitamin supplements with manganese, calcium, molybdenum, and chromium.

YMMV, and “kids, don’t try this at home...”

Yes, and eating olive oil will add half a century to your life.

You are right on the money about fish oil.

My Chinese Herbal Doc uses this all the time in my “tonics.” I no longer have to take my BP meds. BP was 120/79 yesterday.

True Brew is made in Plano and sold in stores all over Texas. You can order online but shipping makes it kind of expensive.

Hmmm. Reminds me of a pro-broccoli study done by a major University a few years ago. Said university just happened to own and harvest several thousand acres of ------ broccoli.

IMPORTANT NOTE: THERE ARE OVER 200 VARIETIES OF HIBISCUS. Do not assume they are all the same. They aren’t.

I would just about give anything to get off of the HBP meds I've been on. For some reason, they either put me to sleep, affect my mental acuity or give me dizzy spells.

Do you have any links to where I can get more information on this?

Some of the herb teas by Celestial Seasonings at your supermarket use hibiscus. Look for teas that are reddish and read the labels, as the ingredients are listed in order of composition.

Besides, if this study gets much press, the market will respond with high hibiscus content teas in short order. Remember when pomegrante juice was touted as a potential Alzheimer's inhibitor a few years ago? Its easy to find pomegrante juice on the shelves now, but I'd just about never seen it in the supermarket before then.

Caffeine no. Sugar?? Check the website that is linked in my original post. Or buy the Hibiscus tea bags and make it however you like it. Cheaper that way too.
