6 year old castrated male Mini Mediterranean Donkey, Stormy, has developed Pemphigus foliaceaus following lice and topical treatment. Has been on Apequel, Hydroxozine, medicated baths, and antibiotics. Corticosteroids are next to be started. The condition has not resolved. Biopsies have been done. What homeopathic remedies may be helpful or other treatments? See attached med file. @dr.Jeff
