The U. S. Food and Drug Administration (FDA) issued a public health alert yesterday at the center of the controversy, over herbal supplement. This issue has been put up one month after a downtown Lawrence store had been raided by the authorities.

Seizing an herbal weight-loss supplement known as Que She, the law enforcement officials had shut down Sacred Journey, 1103 Mass., on 10 June. Very hazardous ingredients are present in these weight-loss tablets, according to FDA.

It said that any person, who had bought these pills, should not intake them, and consult their doctors as soon as possible. Que She had been commercialized as 'an all-natural blend of Chinese herbs', containing active pharmaceutical constituents, which are not detailed on the label that it may harm consumers, particularly to the ones with cardiovascular conditions.

A drug called fenfluramine is an important element in Que She, which had been withdrawn from the U. S. market in the year 1997, as it had caused fatal heart valve damage to many. It also contains various other substances that can be a reason for high risk of heart attack and stroke in patients, who have been suffering from heart ailments.

There were other drugs also detected in Que She, which were the beta-blocker propranolol: a serious element that can cause asthma.
