What is a Psoriasis Remedy?

I am confused by the term that is being used a lot by people trying to sell products to us psoriasis patients.  The term is psoriasis remedy.  The word remedy means cure to me but I know that there is no cure for psoriasis right now.  I don’t know why these people are calling their products remedies.  I think it’s a bit of false advertising to call it a remedy.  I know that they help to make the side effects of the skin disease less brutal but I also know that there is no way to get rid of psoriasis completely, once you have it.
