the Indian traditional system of medicine, Ayurveda. Hibiscus rosa-sinensis or "China rose" is a beautiful, showy flower
native to East Asia, mainly China. It is cultivated primarily as an ornamental plant. Plant breeders around the world have generated several
varieties and hybrids of China Rose giving rise to an enormous array of colors and patterns within the species.
Hibiscus rosa-sinensis leaves are used as a laxative, while the root is used in cough treatment. The flowers are considered to
be aphrodisiac, emollient and emmenagogic and are used in bronchial catarrh, diarrhoea and fertility control. The flowers of H.

All tropical hibiscus are
evergreen, and leaf variation extends from the almost circular leaf to the very narrow, with many in between, while leaf margins can vary from
smooth, or slightly serrated, to highly indented. The flower
classification from, red, brown, white and other colours. Hibiscus
tree are generally found in four sizes of blooms: miniature (under 4 in, or 10 cm), medium
(4-6 in/10-15 cm); large (6-8 in/15-20 cm), and extra large (8 in, or 20 cm, and over). Its leaves are alternate, ovate to
lanceolate, often with a toothed or lobed margin. The flowers of Hibiscus plant are large, conspicuous, trumpet-shaped, with five or more
petals , color from white to pink, red, orange, purple or yellow, and from 4–18 cm broad. Flower color in certain species, such as
"H. mutabilis" and "H. tiliaceus" changes with age. The fruit is a dry five-lobed capsule ,
containing several seeds in each lobe, which are released when the capsule dehisces (splits open) at
maturity. It is of red and white colours.
The major chemical constituents in Hibiscus plant are Flavonoids, Flavonoid glycosides, Hibiscetin, Cyanidine, Cyanidin
glucosides, Taraxeryl acetate, β-sitosterol, Campesterol, Stigmasterol, Ergosterol, Citric, tartaric and oxalic acids,
For all varieties of Hibiscus plant the
basic requirement for healthy growth are: sun and warmth, sharp drainage, ample moisture and nutrients.
Growers now recognize three sizes: tall (6-10 ft/2-3 m), medium (3-6 ft/1-2 m), and low (under 3 ft, or 1 m), in
hibiscus culture the description refers to flower size, not shrub size. From the grower's point of view, the main consideration - apart from,
obviously, choosing the varieties that most appeal- is the space and location for the intended plant.
Always plant out in spring season. A larger plant may need to have any long or heavy bud-bearing stems trimmed back before planting. Handle the
roots gently, leaving the roots and clinging soil uppermost. Observe the spread of the roots: they
spread out at the sides more than down at the center. The planting hole should be wide and shallow, but
well-dug and prepared deeply below, and mounded gently in the middle.
It's important that grafted plants have the graft area kept clear of soil and mulch, so don't plant
deeply. The shallow roots grow close to the surface. Cover lightly and
then water well. While transplanting a long-established in-ground hibiscus to a new
location, it will be necessary to prune it first by cutting back to about two-thirds. It
should be watered very thoroughly a day or two before transplanting. Cover the roots, and water well.
Hibiscus should be planted in the warmest part of the garden where they
receive day-long sun. Sandy loam and good drainage is vital for the
growth. Hibiscus requires high humidity, well-prepared sites that have friable, loamy, good-quality soil with a pH
reading of about 6 to 7, and plenty of organic matter that is routinely
replenished. Like all plants, hibiscus need nitrogen, calcium , phosphorus ,
potassium, magnesium and sulfur as well as trace elements. Good-quality soil
that is regularly enriched with organic matter should contain all of these elements.
The Hibiscus plant have grown for centuries in Indian and Pacific
oceans countries. Hibiscus rosa-sinensis, an old species that was grown as an ornamental
flower in China, is believed to have been cultivated there for hundreds,of years.
It have been in cultivation throughout much of the Asian continent, early reports of H. rosa-sinensis flowering around temples in China imply a Chinese origin,
hence the name "sinensis". Later the East African species H. schizopetalus, as well as H. cameronii -Hawaiian hybridists crossed and
re-crossed them in an extensive program that produced a total of more than 5000 horticultural varieties.
Using Hibiscus flowers for tea has been universally popular throughout history in a great many
cultures and was the drink preferred by the Pharoahs of Ancient Egypt,
who drank Hibiscus tea to invigorate themselves in the desert heat. It is caffeine free with a distinct flavor, and has a lovely aroma.
In the mid-20th century intensive hybridizing work was done in
Florida, and from Hawaii to southeastern U.S.A. Later still, Australian horticulturists began trialing new
cultivars with unprecedented success. By the 1980s there were over 4000 recognized tropical hybrids in cultivation. Today there are more than
10,000 hybrids worldwide. Throughout all of this breeding, H.rosa-sinensis remained the most important genetic parent

A 2008 USDA study shows consuming hibiscus tea lowers blood pressure
in a group of prehypertensive and mildly hypertensive adults. Three cups of tea
daily resulted in an average drop of 8.1 mmHg in their systolic blood
pressure, compared to a 1.3 mmHg drop in the volunteers who drank the
placebo beverage. Study participants with higher blood pressure readings (129 or above) had a greater response to hibiscus tea: their systolic
blood pressure went down by 13.2 mmHg. These data support the idea that drinking hibiscus tea in an amount readily incorporated into the diet
may play a role in controlling blood pressure, although more research is required.

found out that the presence of antioxidants can reduce cholesterol and triglyceride levels in the body.
