Cracked heels can be softened to a great extent by applying the sap of the Peepal tree.
The Latin name is Ficus religiosa or the Sacred fig.*
( This is not to be confused with Ficus benghalensis which is the Banyan tree. )
The leaves have a distinctive shape -kind of heart shape which has a tapering end.
A milky white sap oozes out of the branches and leaves.When this is applied on the cracks they heal faster.
