Drug–herb interactions are also common and can mitigate levitra 20mg expected clinical outcomes of the drug treatment. There are reports in literature where investigators used substandard products, resulting in confusing and biased results. In general, compared to pharmaceutical medications, botanical preparations are expected to act slowly and with a greater variability.
Despite the general belief that herbs are safe, severe side effects may ensue in sensitized individuals. The “active” principles in these products, if present, take time to reach a “therapeutic level.” In some cases, if the herb is taken continuously for a prolonged period it may even reach a “toxic” level. A common issue facing botanical research is the quality of herbs used in study.
In certain studies, patients showed improvement for a particular “herbal” treatment, yet when the product was tested for its contents, no herbal material was found within it!. For example, if echinacea is taken for more than six to eight weeks it can result in the depression of the immune system—an undesirable effect, especially when the herb is expected to enhance the immune system.
