Do you know any medication for foot psoriasis?

The best panacea for skin disease that I know and I've applied it is salt soap bar. It size similar to normal bath soap bar size and light brown. I used it at home and it only cost me for MYR10 = $2.86USD = 107.41 Indian Rupee. Just touch that salt soap bar on the effected skin area, apply it 30 minutes or at least 15 minutes before take bath. It is also available in granules type and must be use by soaking the effected skin area in the mixture of salt and water. For those who has acnes or pimples and athlete's foot is advised to use this salt soap bar.

If I remember rightly someone had a discussion on this some time ago and suggested taking fish oil and using goatmilk soap. Maybe you can search back and find it... good luck...
