HI NANCY! Epsom Salts IS A POWDER/CRYSTALS, AND IT COMES IN A BOX ABOUT 200G BIG. I'M SURPRISED YOU HAVE NEVER HEARD OF IT. A LOT OF OLDER PEOPLE TAKE IT, SO IF YOU KNOW ANY OLDER PERSONS YOU MIGHT WANT TO ASK THEM. MIX ONE HEAPED TEASPOON WITH 1 PINCH OF VIT C POWDER IN A GLASS OF WARM WATER FIRST THING IN THE MORNING. YOU MAY FOLLOW WITH ANOTHER GLASS OF WATER, IF YOU WISH. I USUALLY BRUSH MY TEETH STRAIGHT AFTERWARDS BECAUSE IT TASTES QUITE GROSS (YOU MIGHT WANT TO PINCH YOUR NOSE WHILE TAKING IT). ONLY EVER TAKE THE MIXTURE ONCE PER DAY, OR YOU WILL BE ON THE TOILET EVERY 5 MINUTES- YES, IT'S MIGHTY-STRONG STUFF!! OTHERWISE, TAKE THE BLT MIX.
