If you search the CAFL for Psoriasis, you get some hints.
1. Psoriasis (also use Hypothyroid set and see General Parasite, ascaris, and other roundworm freqs)
** Iodine and supps as per Iodine Support Forum
2. Psoriasis_ankylosing_spondylitis
**Which makes one wonder if there is Threadworm connection and if so then perhaps its dead bodies and much Bromelain is needed
3. Nanobacter (Nanobacterium sanguineum, a nanobacteria which can be found in some calcium deposits in the arteries, kidneys, gallbladder, muscle and joints as well as in increased numbers in those with "autoimmune" diseases such as lupus, psoriasis, scleroderma, and similar disorders)
