Not true. Every RB product that you can buy is stabilized and has Ca added to balance out the P. RB in it's natural state goes rancid faster than you can get it to the stores and has such an inverted Ca:P it's not of value without adding Ca.
I'd add a heaping tuna fish can (6oz) twice a day of ground flax. If he'll eat it get him up to 2 per meal. Flax seed it much cheaper than the prepackaged flax products ($40/50#) as well as fresher (FAs deteriorate quickly when ground). Is his ventral midline raw was well? My gut would say allergies not sweet itch. What other changes can you quantify. Diet, trees, type of grasses in pasture... When does it start/end? Was he anxious in similar situations with he previous owner? I wouldn't put a fly sheet on him. He looks like he's trash it by dinner. If it is sweet itch, putting him up with a fan blowing on him will keep the bugs off.
Hydroxyzine is an rX antihistamine that has been on the market a few years. It's the gold standard when they don't respond to other products. I'd experiment with other OTC products first. Have you tried regular old Benadryl? How much Dex? Liquid or compounded? Some companies that do the compounding hit it on the head with some products while others act like sugar pills. (My mare responds to the liquid given orally but big fat 0 on the powder form.)
