'Resdong' is the Malay word for nose sinus. This is a traditional therapy in some place in Malaysia. The footage have been in Majalah 3 by TV3 few years ago. It shows that the medicine man rubbed some substance from insect to the man's face and then soon after that all the worms come out directly from the face. This treatment is said to able to heal the sinus problem and almost never to re-occur again.
There are more Malay's traditional treatments for the sinus problems such as using medicated smoke and other methods, but i found that this method is more amusing.
