I'm not sure what this stuff is, and luckily I don't get horrendous cramps anymore. (Yay for things changing after kids!) But if I ever got bad cramps again, I would be sure to find out what this stuff is and where I could buy it:).
Here's the solution:
Take 1/2 to 1 teaspoon of crampbark tincture every 2 hours on the days of your worst cramps. Test-tube studies show that this North American plant works as a muscle relaxant to quickly relieve painful spasms.
