Have you visited the tea section of your local grocery store lately? If so, you've seen the dizzying array of herbal tea blends, brands and flavors. There's no doubt that herbal teas are a huge commercial success, and they've been enjoyed for centuries. Many tea lovers buy them for their smell and taste. Others expect herbal teas to be a healthier alternative for other caffeine-containing beverages. Some buy them strictly for the medicinal benefits or effects on the packages.
These claimed medical effects can include calming, soothing, and relaxing. On the other hand, other high-caffeine tea blends may promise increased energy and concentration. Green tea remains a top-seller for its legendary health effects. Is there a dark side to the booming herbal tea business?
Reading The Tea Leaves
In the U.S., the Food and Drug Administration (FDA) has the responsibility to evaluate foodstuffs and medications sold to the public. Herbal teas receive very little regulation. Generally, herbal teas fall into a gray area between foods and drugs. Traditionally, the FDA has considered herbal teas taken only for taste and aroma to be classified as foods. Another FDA "rule of thumb" has been that any herb that is safe for consumption in food is therefore assumed to be safe when taken as a tea. However, the FDA has been taking a closer look at herbal teas and their effects.
Are Herbal Teas Toxic?
That's a difficult question to answer, as the FDA is learning. The large majority of commercial herbal tea blends contain multiple ingredients in relatively small concentrations. These teas are quite safe to drink when used according to the product instructions. Problems arise, however, when people prepare their own herbal teas, deliberately concentrate commercial blends, have an allergic reaction to the tea ingredients, or the tea is incompatible with prescription medications.
What's The Problem?
The problem is one of consumer awareness. Many plants and herbs used in teas have specific and measurable medical properties. Caffeine is one of the best examples. It is a naturally occurring ingredient in both tea and coffee plants. Problems are possible when uninformed persons attempt to medicate themselves with teas.
Some Examples
* Chamomile is reported by some to be both a relaxant and a digestive aid. The chamomile plant is a member of the same plant family as ragweed, asters and chrysanthemums. People allergic to those plants should be cautious of chamomile tea.
* Comfrey tea has been associated with two reported cases of liver disease in the U.S. In one case, the patient abused the herb by drinking nearly a dozen cups of comfrey tea daily as well as consuming many comfrey pills. This extreme herbal dosage continued for over a year, resulting in the liver ailment.
* Lobelia tea can cause vomiting, breathing problems, convulsions, and lead to coma and death when used in large amounts.
* Aromatic sassafras tea in large amounts has caused cancer in lab rats. Oil of sassafras and safrole are the major chemical components of the sassafras oil. These components were banned from root beer decades ago. Although sassafras bark is banned from all food use, extract that contains no safrole is allowed.
Should You Be Scared?
Commercial herbal tea vendors would never willingly endanger you, their customer. Commercially available herbal tea blends are expected to be very safe to drink when prepared according to their directions. Similar to drugs, problems with herbs arise when they are abused or taken in extreme concentrations.
These herbs, even those in commercial herbal teas, can have medicinal effects. Therefore you should always talk to your doctor before using herbal preparations, especially if you use prescription medication. Even if you are not on medication, stop any herb use immediately if you experience unusual symptoms. The symptoms may be an allergy to the herb, or something totally unrelated to the herb. Only your doctor can tell you for sure.
