Problems with feet
Athletes Foot / Tinea
"Athletes Foot, fungal infection of the skin of the foot. The disease, also called tinea pedis, is caused by species of the genus Trichophyton or by Epidermophyton floccosum. Symptoms are a reddish eruption, followed by cracks in the skin between the toes and a watery discharge, accompanied by itching at all stages. It is highly infectious and may be contracted by walking barefoot, particularly on moist floors such as those of bathrooms and swimming pools. The fungus may spread to other parts of the body." - Encarta
Athletes foot can be alleviated by correcting calcium deficiency as the primary remedy. Potassium and sodium phosphate and sulphate as secondary remedies.
I once knew a man who used to get frequent incapacitating gout attacks. After taking a few sodium tablets each day he went a whole year without having a gout attack until he stopped taking them. The sodium phosphate neutralises the uric acid crystals and sodium sulphate helps remove poison charged fluids from the body.
