Final answer:
The 1994 DSHEA allowed herbs to be sold as dietary supplements, transferring safety responsibility from the government to manufacturers, significantly boosting the supplement industry. so, option B is the correct answer.
Step-by-step explanation:
The 1994 Dietary Supplement Health and Education Act (DSHEA) had a significant impact on herbal therapies by allowing herbs to be sold as dietary supplements. This legislation shifted the responsibility for determining the safety of dietary supplements from the government to the manufacturer. As a result, supplements, including herbal remedies, no longer required approval from the U.S. Food and Drug Administration (FDA) before being distributed. However, manufacturers are required to ensure the safety of their products and must notify the FDA if a new dietary ingredient is added to a supplement. Since the enactment of the DSHEA, the supplement industry has seen growth in sales, partly due to this deregulation.
Before the DSHEA, herbal therapies were not regulated as dietary supplements, and manufacturers had to provide evidence to the U.S. Food and Drug Administration (FDA) to substantiate safety.
However, after the DSHEA, responsibility for determining the safety of dietary supplements shifted to the manufacturers, and they no longer had to seek FDA approval before distributing herbal supplements.
