From olden times, yellow python has been used as a tonic. 

The DPRK made a tonic pill, a natural health food, by processing the snake.

The pill prevents stress-borne diseases by improving immunity and exerts strong efficacy on reducing fatigue and retarding the aging. It is also helpful for the treatment of hepatitis as it enhances the test findings of enzyme and liver functions and is efficient in removing jaundice and ascites.
