Herbs are not regulated by the FDA, and are
therefore exempt from investigation and restrictions. What does that
mean? Proof of safety and possible side effects are not required to be
placed on the labels; exact ingredients and the amount and potency are
not required; presence of other herbs or substances are not required on
labels; and last but not least, other substances such as atropine,
steroids, caffeine, and lead can and have been found to be added.
What should you do? Carefully evaluate and
investigate each product prior to using. Read confirmed research
reports, and not just someones advertisement for the product. ASK YOUR DOCTOR!
Don't take any herbs that your doctor isn't aware of your taking. I can
give you a prime recent example, me: In addition to hepatitis B, I have
hypertension and Chronic depression. My antidepressant costs a fortune,
so I decided to try St. John's Wort for the depression. WRONG THING TO
DO! This particular herb has a counter effect on the medicine for my
hypertension! Valuable lesson learned. Thank God I took it only once
before finding additional information, here on the internet, regarding
its interaction with my medicine.
When herbs are used, it is best to introduce them a little at a time, and be aware of the potential reactions. If an ingested herb is either liver toxic or causing a hypersensitivity reaction, damage can be avoided if the ingestion of the offending herb is stopped when adverse symptoms first appear.

Without an ongoing stress, using Silybum or it's extracted silymarins on general principle can actually depress normal liver function.Info from: SOUTHWEST SCHOOL OF BOTANICAL MEDICINE 122 Tulane SE, Albuquerque, NM 87106 (505) 255-9215

complications ranging from acute hepatitis and jaundice to cirrhosis
and death from liver failure! The bottom line is, be careful rather
than sorry. Always check it out with your doctor before trying any new herbal remedy.
FDA Investigates Kava-Liver Disease Link
Reviewed by Michael W. Smith, MD
On Dec. 19, 2001, the FDA announced it was investigating a link between the food supplement kava and liver disease. Federal health regulators said that there have been about 25 cases of serious liver toxicity in Germany and Switzerland, but the agency was not certain if similar problems have occurred in the U.S. Switzerland has already banned the sale of the kava products that have caused the liver problems, and similar measures are being taken to ban all kava products in Germany. Liver problems such as hepatitis, cirrhosis, and liver failure have been reported. In a letter recently sent to doctors, the FDA asked for help in determining if any recent cases of liver problems in this country could be traced to use of kava, which is also known as kava kava or Piper methysticum. Read the FDA letter. The FDA noted it had received several reports of alleged ties between kava and liver problems. There was at least one case of liver failure requiring a liver transplant in an otherwise healthy young woman. Kava is marketed as a food supplement to help with many ailments including stress, anxiety, tension, sleep problems, and PMS.
What to Do
If you use products containing kava extracts, discuss your risks of liver problems with your doctor and whether your liver function should be tested. It also is a very good idea to let your doctor know about any food supplements you use.
