When a man gets sick and he needs medication. If he uses some medication that cures the sickness. He gets well and recovered. This is called right medication.
If he uses some medication that does not cure the sickness, or worse makes the sick get more serious and last for a long time or may kill him, in the worst case. This is called wrong medication.
If he does not want to use any medication or won't use at all, then let him take care of himself or the Death will take care of him.
