Anhidrosis - Silver Lining Pititary, new xiang ru san....?

My mare sweats under the tack when I ride but not really well anywhere else. She’s on electrolytes and OneAC. Been on OneAC about 50 days, so maybe too soon to tell.
Anyone had luck with Silver Lining Pituitary formula or New Xiang Ru San? There is a vet in town that does eastern medicine so could probably get NXRS.
