Which statement is NOT true about herbal supplements?

• A. They can interact with prescription medications.
• B. They are always regulated like medicines.
• C. They can vary in potency.
• D. They can contain contaminants.

Answer: (B)

Herbal supplements don’t go through the same premarket testing and approval process as medicines in many places, so they aren’t always regulated like drugs. That’s why the statement claiming they are always regulated like medicines isn’t true. In practice, these products are often regulated as dietary supplements or traditional remedies, with rules focused more on labeling and manufacturing standards than on proving safety and efficacy before they reach the market. This looser oversight helps explain why potency can vary from batch to batch, why contaminants or adulterants can appear, and why interactions with prescription medications are possible. For example, different lots of the same herb can have different levels of active compounds, processing, storage, and sourcing all affecting potency. Contaminants such as heavy metals, pesticides, or undeclared ingredients can also be present due to manufacturing or supply chain issues. And because their active constituents can influence drug-metabolizing enzymes or have additive effects, herbal supplements can interact with prescription medications.
