Herbal tea
From Free net encyclopedia
An herbal tea, tisane, or ptisan is an herbal infusion not made from the leaves of the tea bush (Camellia sinensis). (Varieties of "real" tea include black, oolong, green, yellow, and white tea.) Tisanes can be made with fresh or dried flowers, leaves, seeds or roots, generally 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 tisane is then strained, sweetened if so desired, and served.

Medicinal concerns
Herbal teas are often drunk for their physical or medicinal effects, especially for their stimulant, relaxant or sedative properties. The medicinal effects of certain herbs is discussed under herbalism. The medicinal benefits of specific herbs are often anecdotal or controversial, and in the United States and elsewhere, makers of herbal teas are not allowed to make unsubstantiated claims about the medicinal effects of their products.
While most herbal teas are safe for regular consumption, some herbs have toxic or allergenic effects. Among the greatest causes of concern are:
- Comfrey, which contains alkaloids that can cause permanent liver damage with chronic use.
- Lobelia, which contains toxins similar in effect to nicotine.
- Pineapple weed, which is sometimes sold as chamomile, is closely related to ragweed and can cause violent allergic reactions in hay fever sufferers, up to and including anaphylactic shock and death.
Any herbal tea with unknown effects should be taken in moderation.
Inexperienced use of wild herbs in herbal tea should be avoided. Poisonous plants can be similar to common herbs, for example, certain deadly nightshade leaves look like comfrey leaves.
