Friend had severe cramps and bleeding during her period, I suggested fennel and fenugreek, to be infused into a tea, this is what I use and it has reduced my duration from 7 to 4.5 days, and reduced bleeding and I don't have cramps any more.
She didn't have any of the ingredients so I suggested curry leaves, infused into a tea. She took a while to get back to me, but she went and got the leaves which took some time. Then the confirmation, about four hours after my advice. Cramps and pain gone, with a smiling emoji. I don't know if she did it again the next day, but I'm secure that she has the knowledge for next time.
