decrystallizing honey

so, its cold and flu season. i have been lucky enough not to have a major bout yet. but, i am getting a bit of scratchy throat probably from yelling too much. so, i thought i would bite the bullet and have some hot tea with honey. i can only stand honey not sugar with hot tea. problem is that honey is rarely used in my house. so, my honey had crystallized. i couldn't remember initially how to fix it and was going to throw the bottle away. a bit later, i remember having heard to fix this problem by placing the bottle in boiling water to warm it. the problem with that is that i have a plastic bottle. so, i tried microwaving 30 seconds at a time. crystals gone. i read online and found almost exactly the same solutions.
