Are there any alternative treatments to use in place of prednisone?

Depends: This depends on what the Prednisone is for. In certain inflammatory cases Prednisone is necessary - but hopefully temporarily. Although ribes nigrum has some steroid properties, it is not nearly as powerful. Have you adressed the root cause of inflammation: dietary allergens, omega-3, probiotics, nutrients (vitamin c, d, a, zinc...)? Find the root cause and then won't need the prednisone.

Homeopathic option: There are homeopathic medicines (remedies) that can assist with inflammatory conditions.
