Interested in natural treatments for psoriasis, insomnia and chronic lower back pain. what are some natural methods of healing/treating psoriasis?

None Proven: Natural treatments are generally backed by little if any evidence of effectiveness.

Anxiety: Often anxiety is a comorbid diagnsosis with psoriasis, which is to say that people with excessive and/or prolonged anxiety may be at higher risk for psoriais. Consider getting a referral to a reputable psychotherapist to help better manage your anxiety. There is nothing more natural and med-free than talk therapy.
