If you believe that herbal supplements are useful to your body because of the "natural", you are wrong, say researchers from the University of Leeds.
For example St. John's wort may reduce the effectiveness of birth control pills, it also affects the effectiveness of the drug for coagulation of sarafina.
Asian ginseng will harm patients with diabetes, and Ginkgo and Echinacea can cause allergies. Even garlic can have a negative impact, as it interferes with the anti-HIV drugs.
According to scientists, consumers need to be more widespread information on the effect of medicinal herbs. A team of scientists from the University of Leeds purchased in pharmacies and big box stores 68 different packages of herbal medicines. In 93 percent of cases, the products were have not licensed, and therefore not tested for compliance to quality standards, and more than half of them were sold as dietary supplements.
Only 13 percent of the drugs contained information sheet, and a reasonable amount of information about the effect of the drug was found only in three packages.
