Herbal Teas

Herbal teas, also known as herbal infusions and less commonly called tisanes (UK and US , US also ), 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).

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. 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 , ''mate'' (yerba mate), and ''rooibos'' (red bush).

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. In any case, the term ''herbal tea'' is very well established and much more common than ''tisane''.

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 as in French, but the original English pronunciation continues to be more common in US English and especially in UK English.)

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 , which came from the Ancient Greek word (), which meant "peeled" barley, in other words pearl barley, and a drink made from this that is similar to modern barley water.

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.

Health risks

While most herbal teas are safe for regular consumption, some herbs have toxin, toxic or allergy, allergenic effects. Among the greatest causes of concern are:
* Comfrey, which contains alkaloids which may be harmful to the liver from chronic use, and particularly is not recommended during pregnancy or when prescription drugs are used; comfrey is not recommended for oral use.
* Lobelia, which contains alkaloids and has traditional medicine uses for smoking cessation, may cause nausea, vomiting, or dizziness at high doses.

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.

Contamination

Depending on the source of the herbal ingredients, herbal teas, like any crop, may be contaminated with pesticides or heavy metals.
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".

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 pregnancy, pregnant individual could cause miscarriage. These include common ingredients like nutmeg, mace (spice), mace, papaya, bitter melon, verbena, saffron, Ulmus rubra, slippery elm, and possibly pomegranate. It also includes more obscure herbs, like mugwort, Ruta graveolens, rue, Mentha pulegium, pennyroyal, Daucus carota, wild carrot, Caulophyllum thalictroides, blue cohosh, tansy, and juniperus sabina, savin.
