Chamomile tea may help beat colds.

  1. Study: Chamomile tea may help beat colds

    NEW YORK (Reuters) -- Tea drinkers, rejoice: new research supports claims that chamomile tea can protect the body from a host of ills, including colds and menstrual cramps.

    During the study, researchers tested the urine of 14 healthy volunteers who drank five cups of chamomile tea every day for two weeks. They found that drinking tea produced changes in the urine that suggest there was an increase in a substance that helps the body fight off colds.

    Tea drinkers also produced higher levels of a substance called glycine, which can ease muscle spasms. This finding may help support claims the tea can relieve menstrual cramps, the researchers note.

    The study clearly shows that chamomile tea produces changes in the body. What remains unknown, study author Dr. Elaine Holmes told Reuters Health, is whether these changes are good or bad overall.

    "There are good reasons why the tea may be beneficial, but these hypotheses require further testing," said the researcher, who is based at Imperial College London in the UK.

    According to Holmes' report in the Journal of Agricultural and Food Chemistry, chamomile is used as an anti-inflammatory, sedative and ulcer-fighter. Research also suggests that chamomile may act as an antioxidant and antimicrobial.

    However, so-called "natural" products are not without risk, experts warn. For instance, chamomile tea can cause a severe reaction in people allergic to ragweed. Chamomile can also affect the absorption of iron, Holmes noted.

    During the study, Holmes and her team tracked urine samples from seven men and seven women who drank multiple cups of chamomile tea every day. The researchers also tested urine samples from the two weeks before and after participants' weeks of tea drinking.

    The researchers found that when participants drank the tea, their urine showed significantly more hippurate, a substance that can act as an anti-inflammatory. Drinking the tea also increased urinary levels of glycine, which may relieve muscle spasms, perhaps explaining reports that chamomile can ease menstrual problems.

    After participants stopped drinking the tea, glycine and hippurate stayed elevated for up to two weeks, which suggests the effects of chamomile tea may be long-lasting, the study authors note.

    Since hippurate is produced by substances in the gut, "it would appear that chamomile, which is known to have antibacterial properties, has changed the bacteria living in the gut," Holmes said.

    "Even two weeks after stopping the intake of chamomile tea, the urine profile did not return to the starting profile, and therefore, the effects of chamomile tea are prolonged," she added.

    The study was funded by Oxford Natural Products plc, which develops plant-derived products.

    Heh... amazing.

    Something I grew up with using and most Europeans have used for centuries... chamomille

    T'aint nuthin' new folks... we've just "boo- hoo'd" this (and so much more) in the name of "western medicine"...

    You guys are welcome.

    I know what Jnette is saying as truth. Western medicine has, for the most part, dismissed this stuff. Up until a couple of years ago chicken soup was considered non-sense.

    I remember growing up in Puerto Rico, and my mom would make me stuff like ginger tea with a touch of butter for a sore throat and chest cold, lemon grass for colds, etc...from our back yard. Stuff that the Indians and Africans used.
