Joanna Stephens (d. 1774) was a healthcare individual who supposedly created a cure for kidney stones and received a £5000 reward for her cure.

Personal life
Joanna Stephens was born in Berkshire, England in the early 1700s. She died at Hammersmith, England on August 6, 1774.

Cure for "the stone"
Stephens created a recipe for kidney stones that included eggshells, soap, calcified snail shells. She initially tested the recipe on 4 men over a year-long treatment period. The men were left with little or no signs of their kidney stones. Stephen Hales advocated for the treatment and advised her to sell the recipe to the English Parliament.

She received a £5,000 from Parliament after the recipe was reviewed and approved by a medical board with little disapproval. She published her recipe on The London Gazette in 1740.
