Alleged Psoriasis cure(s) from Pakistan

On another discussion site there was a post regarding a Psoriasis herbal cure, from a Pakistani gentleman who tried to explain 3 different methods of curing this disease; unfortunately he did not explain the scientific names of the herbs, and he had bad English, so I asked him for clarification and after awhile he got back to my email. Here's the goods (I have no idea of the legitimacy of the claims):

1) He mentioned a "Dr. Reckeweg" who can be reached at info@reckeweg.de; the 4 homeopathic treatments for Psoriasis would be R60 (for blood impurities and chronic rashes), R65 (eczema/psoriasis), R21 (chronic skin diseases w/ rheumatic complaints), and R23 (rashes, eczema, herpes, scabs).

2) Macco (Solanum nigrum) (Pakistani: LINN). Boil this herb and drink its water.

3) Charrita (Swesta chirata) (Pakistani: BUCHHAN) and Sanna Makki (Cassia angustifolia(sp?)) (Pakistani: VAHL). Soak these herbs in water overnight then strain and drink.

He said that all three of these are for the total eradication of Psoriasis however it can flare up after a period of time. He said it's due to liver dysfunction. Again I can't vouch for any of these but for those of you who like to experiment, might want to give this a try. I doubt #2 and #3 would be that pricey. Good luck.
