The subject came up because Cellceutix posted the story of the purchase on their Facebook page. You are hitting on what I believe to be a key point. The other treatments don't target mild psoriasis because the risk reward is not there for the biologics to treat mild psoriasis. Prurisol will definitely have a seat at the table if it works as it did in preclinicals. Safe,effective and in pill form w/o injections. Also less expensive than biologics.
