Green tea is quite refreshing and tasty, and it serves as a natural way to ward off cancer, but if taken in concentrated amount can lead to liver damage. Comfrey tea is very dangerous that it is no longer marketed in the United States, and other unknown harmful herbs have sent many people to hospital for treatment.
New guidelines from the American College of Gastroenterology warns consumers about relying too much on “natural” or “herbal” products, especially in the strong belief that they are safer and performs more better than prescribed drugs.
They’re usually not, a statement from Dr. Herbert Bonkovsky of the Carolinas HealthCare Systems in Charlotte, who assisted in writing the new guidelines.
“A lot of consumers have a preconceived notion that if it’s a natural product, it must be safe. But that is not necessarily the case,” Dr. Herbert says.
“Currently, there is not actually very much effective oversight. It’s pretty much up to the manufacturers of these supplements to guarantee what’s actually in there.”
Some products of green tea extracts may contain big amount of dose of a product. Other times, the products might be infected or contaminated. Most examples are “all natural” fat burning products that contain discontinued prescription drug sibutramine, but phenolphthalein, a laxative that’s also been pulled out of pills because it might cause cancer.
But sometimes it’s the herb itself that is dangerous, says Bonkovsky. “Obviously, there are lots of things in botanicals, hundreds maybe even thousands of compounds,” he said.
Here are five herbs the American College of Gastroenterology is warning about:
GREEN TEA
“Green tea is widely used. If you drink a few cups a day, it is unlikely you will suffer any adverse reaction,” Bonkovsky said. “But the extracts are concentrated formulations.”
The vigorous ingredients are a class of compounds called catechins. “They can reduce or eat u[p some of the protective molecules in cells such as glutathione that are there to protect us from injury. A high dose of green tea extract can lead in susceptible persons to actually quite severe or even fatal liver injury,” Bonkovsky said.
One of the catechins most suspected is epigallocatechin-3-gallate (EGCG).
“We don’t really fully understand the basis for the susceptibility, but it seems likely to be a combination of genetic factors…but also maybe related to their diets, to whether or not they have been drinking alcohol,” he added.
The U.S. Food and Drug Administration have discarded some of the health claims made by manufactures of green tea.
COMFREY (Symphytum officinale)
Comfrey contains has toxic substances called pyrrolizidine alkaloids that damage the liver, sometimes fatally. Comfrey is no longer sold in the U.S., except in creams or ointments, but even used this way the alkaloids can build up in the body.
KAVA
Kava root
Kava kava is made from the roots of the plant Piper methysticum, best known as the basis for a ceremonial drink in Oceania but also sold to treat anxiety and insomnia. It’s been documented to have cause liver damage in as many as 100 people, however, and its use is banned or restricted in Germany, Switzerland, France, Canada, and Britain.
SKULLCAP (scutellaria incana)
Skullcap was traditionally used by Native Americans to treat anxiety, stress and insomnia. Chinese skullcap is a different species, but both are suspected of causing liver damage. Skullcap is often used in products containing multiple herbs, so it’s not entirely clear that skullcap is entirely to blame. But it’s something to keep an eye on.
CHAPARRAL (Arctos taphy los luciana Adelaide Manzanita)
Chaparral, an extract of a shrub known as creosote bush, is used by people believing it can benefit conditions ranging from skin rashes to cancer. The suspected liver-damaging compound is one called NDGA. It’s possible that people with liver injury from the herb are having a type of allergic or immune reaction to it. But it’s been severe enough in some cases to have forced an emergency liver transplant.
Liver injury is difficult to diagnose, Bonkovsky says. “Symptoms are pretty non-localized,” he said. They can include feeling tired, low appetite, a feeling that food isn’t as tasty as usual. “There might be some pain in the area of the liver, in the right upper part of the abdomen,” he said. Jaundice – yellow skin – is a big red flag, as is dark-colored urine.
“If people have any sign of that, they should stop whatever they are taking and seek medical attention,” said Bonkovsky.
Note: Green tea and other herbs are nutritious but are not to be taken over dose, it causes serious malfunctions (disease) in the body system.
