An Ingrowing Toe Nail
Put a small piece of tallow in a spoon and heat it very hot and pour it over the granulations. This acts like magic.

Nails (Ingrowing)
Scrape surface — a piece of glass is good for this purpose. Cut in V-shape. Pack absorbent cotton under affected side. Paint with iodine.

For Ingrowing Toenail
Take one drachm of muriatic acid, one drachm of nitric acid, and one ounce of chloride of zinc. Apply one drop of this mixture to the affected part once a day. This gives instant relief to the pain caused by ingrowing toenail.
