Herbal tea made from hibiscus beginning to steep
Herbal tea made from hibiscus beginning to steep

Herbal teas—less commonly[1] called tisanes (UK and US /tɪˈzæn/, US also /tɪˈzɑːn/)[2]—are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. They do not usually contain caffeine.[3] Herbal teas should not be confused with true teas (e.g., black, green, white, yellow, oolong), which are prepared from the cured leaves of the tea plant, Camellia sinensis), nor with decaffeinated tea, in which the caffeine has been removed. Like beverages made from true teas, herbal teas can be served hot or cold.

Origin

Herbal Tea “has a long history from Southern China, especially in Guangdong Province. Because of the weather of the southern China was damp heat “濕熱” and many people having a business activity here so that If they feel sick, they will drink a cup of Herbal Tea ”涼茶”.[4]

According to the earliest record of Guangdong, Herbal Tea was appeared from the Yuan Dynasty before 1751"公元1751年前元代的" AD <<嶺南衛生方>>. Also, they will name the Heat soup”清熱的湯” as a cold medicine”涼藥”. However, because of the meaning of the medicine, Chinese did not like the meaning of medicine so that they changed the name as Herbal Tea in Qing Dynasty “清代”.[5]

The ancestor of herbal tea is Wong Lo Kat “王老吉” [6], it was created by Wang Zebang “王澤邦” in 1828. The operation style of the earliest herbal tea shop was Street vendors “路邊攤”, [7]they will selling on the street. In 1869, Herbal Tea was appeared in Hong Kong.[8]

On May 28, 2006, the herbal tea was formally approved and published as a national intangible cultural heritage.[9]

Etymology

Some feel that the term tisane is more correct than herbal tea or that the latter is even misleading, but most dictionaries record that the word tea is also used to refer to other plants beside the tea plant and to beverages made from these other plants.[10][11] In any case, the term herbal tea is very well established and much more common than tisane.[1]

The word tisane was rare in its modern sense before the 20th century, when it was borrowed in the modern sense from French. (This is why some people feel it should be pronounced /tɪˈzɑːn/ as in French, but the original English pronunciation /tɪˈzæn/ continues to be more common in US English and especially in UK English).[2]

The word had already existed in late Middle English in the sense of "medicinal drink" and had already been borrowed from French (Old French). The Old French word came from the Latin word ptisana, which came from the Ancient Greek word πτισάνη (ptisánē), which meant "peeled" barley, in other words pearl barley, and a drink made from this that is similar to modern barley water.[12]

Health risks

While most herbal teas are safe for regular consumption, some herbs have toxic or allergenic effects. Among the greatest causes of concern are:

Herbal teas can also have different effects from person to person, and this is further compounded by the problem of potential misidentification. The deadly foxglove, for example, can be mistaken for the much more benign (but still relatively toxic to the liver) comfrey.

The US does not require herbal teas to have any evidence concerning their efficacy, but does treat them technically as food products and require that they be safe for consumption.

Fruit or fruit-flavored tea is usually acidic and thus may contribute to erosion of tooth enamel.[15]

Contamination

Depending on the source of the herbal ingredients, herbal teas, like any crop, may be contaminated with pesticides or heavy metals.[16][17] According to Naithani & Kakkar (2004), "all herbal preparations should be checked for toxic chemical residues to allay consumer fears of exposure to known neuro-toxicant pesticides and to aid in promoting global acceptance of these products".[16]

During pregnancy

In addition to the issues mentioned above which are toxic to all people, several medicinal herbs are considered abortifacients, and if consumed by a pregnant woman could cause miscarriage. These include common ingredients like nutmeg, mace, papaya, bitter melon, verbena, saffron, slippery elm, and possibly pomegranate. It also includes more obscure herbs, like mugwort, rue, pennyroyal, wild carrot, blue cohosh, tansy, and savin.[medical citation needed]

Composition

Herbal teas can be made with fresh or dried flowers, leaves, seeds or roots. They are made by pouring boiling water over the plant parts and letting them steep for a few minutes. Seeds and roots can also be boiled on a stove. The herbal tea is then strained, sweetened, if desired, and served. Many companies produce herbal tea bags for such infusions.

Major varieties

While varieties of herbal teas are defined as any plant material for infusion, below is a list of common herbs:
