A brief history of tea

Tea initially began as a medicinal drink and overtime evolved into a beverage. It is said that in the year 2737 the Chinese emperor, Shen Nung, was sitting underneath a tree while his servant boiled drinking water, when some leaves from the tree blew into the boiled water. The leaves were from the tree called Camellia sinensis. The emperor decided to try the water-leaves infusion that we now know as tea. Today Camellia senensis is responsible for majority of the tea used worldwide.

Hibiscus tea

Hibiscus tea, also known as sour tea, is among the healthiest beverages. It is known for its nutritional and therapeutic benefits. The most common variety for tea making is Hibiscus sabdariffa (roselle), a herbaceous perennial that is native to Africa. The calyces and flowers are used to make tea, spices, jam, wine, and syrup

In Nigeria, Hibiscus is known as isapa or yakuwa or ashwe. It is used to make soup by cooking the calyces. Hibiscus is used to make Zobo drink, a popular local beverage. It is also used as dye.

In most parts of Africa and the world, Hibiscus calyces are used to make tea and soda. Even though the calyces are usually used, other parts of the plant (such as the leaves, seed, and roots) are also safe to consume. The fibre extracted from the stem is used to make cords, ropes, sacks, and twine.

In South Africa, Hibiscus beverages are not sold commercially or promoted for nutritional and therapeutic benefits. As a herbal product, it has great potential. Obesity, high blood pressure, immune compromising diseases such as HIV, and diabetes, are prevalent in South African and Hibiscus can be used to manage them.
