What's in those supplements? It might be "houseplant."

The evidence for these herbs’ effectiveness is sketchy to begin with,” said David Schardt, Senior Nutritionist of the Center for Science in the Public Interest. “But when the advertised herbs aren’t even in many of the products, it’s a sign that this loosely regulated industry is urgently in need of reform. Until then, and perhaps even after then, consumers should stop wasting their money. Attorney General Schneiderman has done what federal regulators should have done a long time ago.

Unless you've been told by your physician that you are lacking or low on some kind of nutrient or vitamin and you're unable to consume or generate this missing thing, you likely don't need a supplement (Americans have the most expensive pee in the world.) I'm so glad someone is finally taking on these companies. Lying about the health benefits is one thing, but not even selling the thing you're advertising? Unconscionable. I'm definitely sympathetic to wanting to feel better and being willing to try over the counter options (especially if you don't have health care), and I understand the power of the placebo effect... but people trust these companies. What if the mystery ingredients are contraindicated for a medication? 

Some of the contaminants identified include rice, beans, pine, citrus, asparagus, primrose, wheat, houseplant, wild carrot, and others. In many cases, unlisted contaminants were the only plant material found in the product samples.

I wonder if houseplant is contraindicated for any meds?
