Is there an economic opinion on "bullshit" products/markets and how they work?

Lately after searching the internet and buying products. I notice there are a lot of services and products that thrive on uncertainty, buyer desperation, and fog of war to sell. And if buyers had more information I imagine these bullshit products wouldn't sell. For example tons of "herbal" products, coaching, and informational products that actually lackluster?

I was wondering has economics spoken on the topic of this market of "bullshit" products and is there anything that takes an economics lens and focuses on exploring the nature of these bullshit items. 

Further details: I know scamming isn't new, but these technically aren't scams (or maybe so). The product or service is being offered it just doesn't meet the needs the consumer was hoping to address during the purchase.

Some of this falls into the area of asymmetric information. One type of goods is credence goods. These are goods in which you can't learn the true quality of the product even after consuming it. As opposed to search goods, goods in which quality can he learned by inspection, and experience goods, in which quality is learned by consuming it. Credence goods usually involve a diagnosis or some kind of "expert". For things like herbal supplements you can someone saying you have this problem this product will help. Even after you consume it, maybe it helped, maybe it didn't. maybe you didn't have a problem at all. More generally it seems you are interested in information asymmetry.
