Jack Beans to treat eye discharge

This one is introduced to me by my mom. She says that Jack Bean has the function of healing people with extra eye discharge and also remove the "wet heat" in the body.

Hmm...how should I describe the "wet heat" mentioned by Mom?

Chinese believe that if our body has "wet heat", one will have a lot of eye discharge and loose stool.

Ingredients:
RM2 of Jack Beans
1 handful of Hong Chou (Red date)
1/2 handful of Kei Chee (Wolfberry)

Put to boil for 2 hours and it's ready!
