Herbal teas, also known as herbal infusions and less commonly [2] called tisanes (UK and US /tɪˈzæn/ , US also /tɪˈzɑːn/ ), [3] are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. Oftentimes herb tea, or the plain term tea, is used as a reference to all sorts of herbal teas. Many herbs are used in herbal medicine. Some herbal blends contain actual tea (e.g., the Indian classic masala chai).

Contents

The term "herbal" tea is often used in contrast to the so-called true teas (e.g., black, green, white, yellow, oolong), which are prepared from the cured leaves of the tea plant, Camellia sinensis . Unlike true teas (which are also available decaffeinated), most tisanes do not naturally contain caffeine. [4] [5] There are a number of plants, however, that do contain caffeine or another stimulant, like theobromine, cocaine or ephedrine. Some have the opposite effect, acting as a sedative. Some common infusions have specific names such as coffee , mate (yerba mate), and rooibos (red bush).

Herbal tea in a glass teapot and cup

Some feel[ clarification needed ] 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. [6] [7] In any case, the term herbal tea is very well established and much more common than tisane. [2]

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.) [3]

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. [8]

Composition

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

Varieties

While varieties of tisanes can be made from any edible plant material, below is a list of those commonly used for such:

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. Care must be taken not to use any poisonous plants.

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 individual 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 ]

Although health benefits have been assumed throughout the history of using Camellia sinensis as a common beverage, there is no high-quality evidence that consuming tea confers significant benefits other than possibly increasing alertness, an effect caused by caffeine in the tea leaves. In clinical research conducted over the early 21st century, tea has been studied extensively for its potential to lower the risk of human diseases, but there is no good scientific evidence to indicate that consuming tea affects any disease or improves health.

<span class="mw-page-title-main">Tea blending and additives</span> Blending different teas together

Tea blending is the act of blending different teas together to produce a final product that differs in flavor from the original tea used. This occurs chiefly with black tea, which is blended to make most tea bags, but it can also occur with such teas as Pu-erh, where leaves are blended from different regions before being compressed. The most prominent type of tea blending is commercial tea blending, which is used to ensure consistency of a batch on a mass scale so that any variations between different batches and seasons of tea production do not affect the final product. However, it is also common to blend tea leaves with herbs and spice, either for health purposes or to add interesting and more complex flavor notes. It is important that any one blend must taste the same as the previous one, so a consumer will not be able to detect a difference in flavor from one purchase to the next.

Infusion is the process of extracting chemical compounds or flavors from plant material in a solvent such as water, oil or alcohol, by allowing the material to remain suspended in the solvent over time. An infusion is also the name for the resultant liquid. The process of infusion is distinct from both decoction—a method of extraction involving boiling the plant material—and percolation, in which water is passed through the material.
