Salicylate downregulates 11β-HSD1 expression in adipose tissue in obese mice and hence may explain why aspirin improves glycemic control in type 2 diabetes.  Epigallocatechin gallate from green tea can also potently inhibit this enzyme,  green tea is a complex mixture of various phenolics with contents varying with production and processing, some of the phenolics are known HDAC inhibitors that alter genetic expression. EGCG as usually consumed in green tea is poorly absorbed into the bloodstream, more research is needed to reach firm conclusions.
There is variation in the literature with regard to dosage regimens. Prednisone mg/kg/day to 1 mg/kg/day PO is commonly reported, followed by gradual taper over 3 to 6 weeks. Use of IV methylprednisolone for a few days may precede oral corticosteroid use. NOTE: Following biopsy to confirm diagnosis, corticosteroids are usually instituted soon afterward as an adjunctive measure; removal of the suspected offending agent /cause is the primary treatment. While many case reports suggest a possible net benefit to the use of corticosteroids, some experts advocate for more prospective study of their value.
