Is there a natural remedy i can use to replace kortisone?

Topical, yes: Topical hydrocortisone is often used for skin inflammation/other skin conditions. Chamomile, licorice, chickweed creams & witch hazel all seem to have some anti-inflammatory effects. The saponins in the Yucca plant are precursors of natural cortisone produced by our adrenal glands & products containing this have helped arthritis. However, if you have systemic adrenal insufficiency, NEED cortisone
