What is Hibiscus?

Before we get into the health benefits of this exceptional tea, we must first look into hibiscus as a plant and its beneficial components. Hibiscus tea is a beverage made by infusing the so-called Roselle flowers in hot or cold water. The Roselle flowers are actually Hibiscus sabdarifaa, a plant that is a member of the Malvaceae family. The flowers and the plant, in general, are medicinal and there are over one hundred species. Hibiscus usually grows in tropical and subtropical regions, where there is a variety in soil and the climate is warmer. Such regions can be found in North Africa, Southeast Asia, the Caribbean, Central, and South America.

The plant is mainly grown and cultivated mainly for its flowers, or Roselle blossom. Because it has so many varieties, it is important to know that not every variety is safe for consumption. There are several species cultivated primarily for food and drink consumption, as well as a supplement added to medicine, or simply used in traditional medicine. The application of the plant is versatile; mostly because of its numerous health properties it is used for different treatment and disease management.

Hibiscus – Chemical Composition

The chemical composition and bioactive compounds found in Hibiscus make this plant medicinal. Among vitamins, proteins, and carbohydrates the plant provides, it is mainly cultivated for its calyx (also known as the outermost flower parts). Even though there are different types of Roselle flowers (like green, white or dark red), the red calyx is mostly used for its safe and rich chemical composition.

Studies have shown that the main compounds, which are also responsible for the Hibiscus therapeutic effects, include as following;

  • Organic acid (Hibiscus and hydroxycitric acid) – usually responsible for the flavor characteristics of the calyx. The acid also contributes to the regulation of pH and the inhibition of enzymes.
  • Phenolic acids and components (catechin, gallic acid, caffeic acid, salicylic acid, etc.) – usually responsible for the dietary antioxidants in the calyx. Phenolic compounds also play an important role when it comes to anti-inflammatory and anti-tumor properties of the plant.
  • Flavonoids (hibiscitrin, luteolin, etc.) – usually responsible for the inhibition of fat accumulation and reduction of body weight. Flavonoids also block lipid accumulation in the liver and decrease cholesterol levels.
  • Alkaloids – usually responsible for the anti-microbial effects and properties of hibiscus. They also help the body fight off diseases such as cardiovascular diseases or prevent heart attacks and strokes.
  • Other compounds – include minerals, amino acids, vitamin C, calcium, iron, niacin, riboflavin, thiamine, carotene, anthocyanin (naturally occurring pigment), and other, medically important compounds.

Hibiscus Tea Overview

Hibiscus tea is consumed all over the world, and there are, of course, varieties in which it is made. It can be served either hot or cold; dried Roselle flowers are brewed in hot water, as regular tea, or can be cold-brewed in cold water, overnight. Throughout the world it is either consumed or named differently, for example; in West Africa, this beverage is known as bissap, or as Orhul in India and Ayurvedic diet. In Jamaica and the Caribbean, it is known as sorrel. In Cambodia, the tea is brewed until the leaves have no more color, and then lime juice is added to the beverage. Elsewhere, the tea is paired with raw honey, sugar and cold water or ice cubes.

Dried Roselle petals are also edible on their own, so they can be used, for example, as a vegetable (in the Philippines), or as an indispensable ingredient for soups. In the Indian Ayurvedic medicine, hibiscus and Roselle petals are indispensable for their medical properties. Speaking of medical properties, it is time to see which health benefits the hibiscus tea really provides.
