Mixing Medications With Herbs Spells Trouble

It is generally accepted that prescription medications may have side effects, and there is also the belief that herbal medicines are more desirable, as they cannot possibly have dangerous side effects.
An anonymous survey of rheumatology patients in the United Kingdom shed some light into the use of over-the-counter herbal remedies: nearly half of the patients (40%) had used herbal remedies in the past six month in the hope of enhancing their health. Trouble started for one in ten patients who took an herbal remedy that could negatively interfere with their traditional medicines. Dr. Wendy Holden of the Nuffield Orthopedic Center in Oxford, the author of this study, reported that the risk is especially high for rheumatology patients who take anti-inflammatory drugs in combination with herbs. The traditional medicines do have a risk for gastrointestinal bleeding, however the additions of herbs like ginkgo biloba, ginger, devil’s claw and even garlic can increase the anticoagulant effect and bleeding may be the consequence. Some patients who reported the use of Echinacea were increasing the risk of a liver disease. Of those patients who took a potentially harmful treatment combination 92% were unaware of the risk. Less than half had mentioned to their physicians that they used herbal medications in combination with their prescription medications.

Herbal medicines are powerful and their effects and side effects have to be taken into consideration. It is important for the patient to mention every medication, even the seemingly harmless over-the-counter herbal remedies, to the treating physician, as the mix may be not a winning combination, but one that is hazardous.

Study Shows Echinacea Not Effective For The Common Cold

A study shows echinacea not effective for the common cold. 148 college students participated in this experiment at the University of Wisconsin. The researchers wanted to see whether Echinacea was more effective than placebo (“fake pills” with no herb in it). The Annals of Internal Medicine (Ann Intern Med 2002;
137:939-946,1001-1002) published this study recently.

How they did the experiment

The students were given 1 Gram capsules of a mixture of Echinacea herbs that can he bought in health food stores. With the onset of the common cold the students were given 1 capsule 6 times daily for the first day and three times daily from the second to the 10th day. The researchers examined all the students in the placebo group and the Echinacea group for symptoms, duration of the cold and the severity of the cold. The mean duration for both groups was 6 days. None of the criteria in measuring the severity of the cold symptoms were different in both groups. Dr. Barrett, the lead investigator concluded that there was no measurable difference between the two groups, but added that the findings of this trial should not be “the last word” on Echinacea. More studies need to investigate this matter.

Conclusion

Here is the problems with the study.  The investigators assumed that a placebo pill would not have an effect. However, countless other studies have shown that a placebo often has a 15% to 20% effect. On the other hand it is difficult to have another control for this by not taking any pill. It would be obvious to the subject in the trial that they are the negative control. A negative placebo effect would kick in. So, don’t stop taking Echinacea yet, if you have been taking this normally to treat a common cold. But those of you never took it in the past, you may want to wait first. See what other studies will say in future regarding Echinacea.
