I've been recommending hibiscus tea to lower high blood pressure.
In the Philippines, hibiscus is known as gumamela. Many Filipinos are not aware that you can make tea from gumamela flowers.
There are different varieties of hibiscus or gumamela and the kind generally used for medicinal tea is hibiscus sabdariffa - see pictures above. The calyx is used for tea.
However, the common gumamela that abounds in the Philippines can also be used for tea - see this youtube link. I'm not sure if the benefits are the same as the hibiscus sabdariff. My guess is that the gumamela flower has many benefits as well.
To summarize: the hibiscus sabdariffa is the one used for medicinal tea, which can lower blood pressure. The common gumamela flower can still be used for tea, although I'm not sure about the medicinal value.
I got this info from the net:
It's very simple to make: 1 cup karkadeh (Hibiscus Flower Petals) and water and sugar.
* In a jug, pour boiling water.
* Add karkadeh and sugar.
* Stir till sugar dissolves.
* Leave for a couple of hours till water becomes dark red.
* Drain karkadeh in a fine hole sieve to leave out karkadeh leaves.
* Cool in refrigerator until serving, or serve hot. "
More information on wikipedia.
Hibiscus is used for treating loss of appetite, colds, heart and nerve diseases, upper respiratory tract pain and swelling (inflammation), fluid retention, stomach irritation, and disorders of circulation; for dissolving phlegm; as a gentle laxative; and as a diuretic to increase urine output.
In foods and beverages, hibiscus is used as a flavoring. It is also used to improve the odor, flavor, or appearance of tea mixtures.
