INTRODUCTION:

Roselle Description Hibiscus has 300 species distributed around the world in tropical and subtropical regions and is used as ornamental plants. Studies have shown that certain Hibiscus species have some medicinal properties, of which roselle is one. Usually, Hibiscus sinensis is known as "red sorrel" or "roselle. “Even though permeable soil is that the best, Roselle can adapt to a spread of soil during a warmer and more humid climate.¹A part of the Malvaceae family, Hibiscus sinensis is a well-known medicinal plant with a worldwide reputation. In most warm countries, such as India, Saudi Arabia, Malaysia, Indonesia, Thailand, the Philippines, Vietnam, Sudan, Egypt and Mexico, the plant is also found.^2,3 Roselle is especially cultivated to be consumed and therefore the main producers of Roselle blossoms are Egypt, Sudan, Mexico, Thailand and China. Other hibiscus varieties are planted for his or her fibers they produce. Hibiscus is belongs to the Malvaceae family, and its scientific name is China rose. it's an evergreen which is approximately 150-270cm tall. It’s strong branches and trunk; the leaves are dark green, shiny, smooth, and oval-shaped.^3,4 This plant doesn't bear any fruit. Flowers are found in various shades e.g. red, white, yellow, and orange. Red hibiscus flowers are quite common and widely used for medicinal purposes. This drink is usually consumed iced, and is usually sweetened. it's a sour flavor and bears some resemblance to fruit juices. Although the dried tea seems like it's made up of petals, it's actually made up of the sepals (calyces), the tiny structures at the bottom of the flower. Many species of hibiscus are grown ornamentally, but the species roselle (also referred to as roselle) is that the commonest one utilized in herbal teas. China rose, or China rose, is additionally sometimes wont to produce herbal teas, but this text focuses on the sabdariffa species.^5,6 The roselle species are often grown commercially, as a perennial, in hot tropical areas, or as an annual in colder climates. Hibiscus is additionally one among the foremost common ingredients in herbal blends; it even occurs because the main ingredient in many herbal blends widely available in supermarkets within the U.S. Hibiscus is quite acidic, and its commonest use in blends is to impart a sour taste and red or purple color, although it also imparts aroma also .In history, the medicinal plants are widely used for the varied purposes.^7,8 The plants have identified as medicinal plants due to the power to synthesize chemical compounds which play major role to stop different diseases like cancer, diabetes, etc. a strong verity of chemical compounds also have essential biological roles, and to protect against attack from predators including fungi, insects and herbivorous mammals. So far, at least 12,000 such compounds are isolated; variety estimated to be less than 10% of the total, medicinal plants are also considered and split into three significant sectors: (a) modern medicinal products using approximately 30 to 35 medicinal plants; (b) traditional medicinal products arranged and codified with written treatise texts, such as Ayurveda, Siddha, Unani, Amchi and Amchi. (c) local health traditions that are supported traditions practiced by villagers, folk healers, vaidyas, and tribal people that use quite 8,000 species of medicinal plants for primary health care purposes.^9,10 The herb Hibiscus rosa sinensis L. (Malvaceae) is native to China. Many species of Hibiscus are grown for his or her showy flowers. it's a shrub widely cultivated within the tropics as a decorative plant and has several forms with varying colours of flowers. Hibiscus also has medicinal properties and is used in many herbal teas as a primary ingredient. In medicine, the red flowered variety is preferable. The taxonomy and therefore the name of Hibiscus flowers is shown in the Table in different regions. Different studies have shown that species of Hibiscus plants have different medicinal properties. This review focused primarily on the therapeutic potential of and applications of the Hibiscus rosa sinensis plant.^11,12

Origin of roselle:

There is an enormous argument about the origin of Roselle among different scholars. Cobley suggested Roselle may be a native plant of West Africa and from there it had been carried to other parts of the planet like Asia and America, whereas in others opinion.^13,14Roselle was originated from India and Saudi Arabia. Varieties of Roselle Among numerous verities of Hibiscus, Hibiscus altissima and Hibiscus sabdariffa are the most typical and better introduced. Hibiscus altissima is branchless plant with yellow flowers and red or green colored calyxes. Though this species isn't used for food, this plant is more economically important than roselle because of its high fiber content. The opposite distinct type Hibiscus sabdariffa or “Roselle” grows during a bush with many branches.^15,16
