If you have bad odour on your foot, soak your feet with Epsom Salts. You can also add 2 cupfuls of Epsom Salts to soak in your bath to help with aches and pains. Epsom Salts contain magnesium which is absorbed through your skin, which is a good thing.
for getting rid of foot odour in your shoes, sprinkle Bicarbonate of Soda. This can be purchased in the supermarket in the bakery section and also at the pharmacy.
You can purchase Epsom Salts from the web at a reasonable price and you can also choose which size you wish to purchase.
I would not advise soaking your feet in urine.
Wash your feet every day and wear clean cotton socks every day. Cotton socks allow your feet to breath. The more cotton in the fabric, the better.
Hi don't know about the black tea , but i think your own Urine is good for the Feet i believe , take care ,
