I used to live in a town in Davao Oriental, where people religiously follow the herbal medicine to relieve their illnesses. When stomachache happens, they use tuba-tuba or Jatropa Curcas, as their solution to the pain. What they do is, they first make the patient relax and let the patient drink lukewarm water for the stomach. Then they get several leaves of tuba-tuba and they steam it for at least 10 seconds. Then they place the leaves in the stomach area of the patient and wrap it with clean cloth. They let the wrap stay there for 2 hours. Usually, the patient sleeps when the procedure is applied. When the patient wakes up, the pain in the stomach is relieved by the tuba-tuba leaves wrap.
