Herb Gardening - Medicinal Herbs

Few places house more junk science than in the advertisements of herbal medicines. Near miraculous claims are made that haven't been tested or substantiated. Nevertheless, some herbs have, in fact, been used for thousands of years to help treat a number of conditions. Here are a few herbs that have been examined by leading research firms, along with possible benefits and side effects.

CHAMOMILE

Chamomile is an herb made from the dried flower of the same name. It's often used to make a tea that is both tasty and safe. It has a soothing effect and can be used as a mild sedative.

It's been claimed that chamomile can reduce inflammation and fever though this hasn't been proved. Some studies suggest that compounds in chamomile can inhibit certain bacteria linked to stomach ulcers. But the results are inconclusive.

Some individuals may be allergic to the pollen of this daisy-like flower, but for most the herb is safe even if not quite the miracle cure it is sometimes said to be.


ECHINACEA

Echinacea is a perrennial containing a number of substances that have been well studied. It has been used to treat upper respiratory problems produced by colds. It's sometimes thought to help the immune system. None of the claims made for it have been completely validated, however.

Some studies have suggested that it can help reduce the duration of colds and ease symptoms. Others have shown that it can reduce the frequency of catching colds. These claims are hard to prove, since there are so many factors that are operative whenever someone gets a cold, but at least the herb is generally thought to be safe. If nothing else, it might be a good placebo.

Individuals with diabetes are cautioned to seek the advice of a physician before taking Echinacea, however.


FEVERFEW

A bushy perrennial, feverfew contains active ingredients parthenolide and glycosides that it's believed may help in the treatment of inflammation and migraines. There is some support for the notions, since feverfew does tend to reduce clotting effectiveness.

But, there are some potential side effects, such as skin inflammation and mouth ulcers. Heart rate can be raised and it can interact with drugs taken for migraine. It may reduce the absorption of iron.

The jury is still out on this one.


GINSENG

An ancient herb, used in China and India for thousands of years, it's derived from the ginseng plant and used in hundreds of forms. Studies suggest it reduces blood sugar levels and increases HDL (high-density lipoprotein), the 'good' cholesterol.

Though safe, there is no evidence that it can actually enhance sexual performance. However in this area a placebo is often as good as an actual active ingredient. Sometimes, if you think you can, you can.

Ginseng has compounds similar to estrogen, though, and pregnant or breastfeeding women should avoid taking it. Asthma attacks have been induced in some people by taking large quantities. Also, it can reduce blood sugar levels to unhealthily low levels.

Anyone seeking to use herbs as medicine should try to get the best information possible before risking his or her health. There is much anecdotal evidence, based on thousands of years of use, that some can be beneficial. But, it's difficult to evaluate those experiences objectively. Proceed with care.
