Does anyone know how to calculate odds ratio in its original scale from the coefficient and/or odds ratio from a logistic regression model which includes a natural log transformed independent variable?

For example,
logit (p/(1-p)) = b0+ b1 In (x)

If b1=0.1, (b1 is the coefficient of natural log transformed independent variable)

What is the OR for one unit increase in the natural log of x? What is the OR for one unit increase in original scale of X?

What is the OR for 5-unit increase in natural log of x? What is the OR for 5-unit increase in X?
