I'm  suffering from psoriasis  from last six year. Now I switch to homeopathic treatment from last 5 month and there is improvement in my conditions but from last 20 days it seems that my medicine is not working properly as it used to, and this all take place when I return back to my native state from Bangalore. I think environment change may be a reason so which medicine of what power should I take for activation of my psoriasis medicine.
