The manufacturer of an injectable herbal remedy blamed in three deaths in China's southwest has voluntarily widened its recall, the nation's drug monitoring agency said Saturday.

Wandashan Pharmaceutical Co. based in the northeastern province of Heilongjiang is now recalling all of its injectable products throughout the country, the State Food and Drug Administration said on its Web site.

Previously, only the sale of two batches of an injectable remedy containing the extract of an herb called ciwujia, a type of Siberian ginseng, had been suspended and sent to the SFDA for testing.

The action comes as China is trying to reassure consumers over a widespread tainted milk scandal, the latest to mar its already troubled product safety record.

The SFDA said local food and drug bureaus should monitor the injection recall and make sure the products are pulled off shelves. Any adverse reactions should be immediately reported, it said.
