MIAMI -- In the search for the perfect body, many Americans are taking short cuts.

"Forever people have been trying to lose weight using some magic potion, lotion, pill or powder," said Dr. Maritza Paz, a specialist in herbal and alternative medicine.

A product from China called Fruta Planta is a big seller on the internet, but Paz says buyers should beware.

The package is riddled with spelling errors, warnings of heart attack and nonsense statements such as "take easily specially the same day never healthily safely." Yet consumers continue to buy these diet pills.

"This particular product has something called sibutramine, which is related to amphetamines," said Paz.

Beyond that, Paz said it's hard to know what's in the product, and that's reason for concern.

"It does trouble me that you can't even read an ingredient list," she said. "What people don't understand is that even though a product is herbal and so-called natural, it can have adverse affects on your health."

The label, which is riddled with spelling and grammatical errors, suggests using the supplement could cause heart attack, high blood pressure and serious disease.

The Food and Drug Administration urges consumers to contact the agency with information about reactions to over-the-counter products.
