The use is to roll the sulfur stick from bottom to top, with light pressure for 4-5 minutes on the painful area.
The advice is to store the torches in the refrigerator or freezer. They can be used multiple times. In the event of strong negative electrostatic discharges, you may hear slight crackling sounds from the sulfur torch, these are indicative of a rapid absorption of the tensions present in the area.
It is possible that the torch itself will break into one or more pieces or crumble slightly, indicating that it has absorbed negative electrostatic charges. It is necessary to continue rolling the torch until the popping sounds are no longer heard.
After the treatment, the sulfur sticks can be rubbed with a sponge or passed under running water for about a minute, in order to discharge the negative energy that has been accumulated; they can then be used again.
