last time i also used to have menstrual pain ^^"

after that my mum always boil me ba chen and give me eat bak fung yin once a month after menstrual. Beside that, avoid drinking cold drinks as much as possible and drink more warm water. When menstrual hit, you won't feel pain anymore

thats I dont know ohh.. i never drink dong quai so much. been drinking ba zhen for many years. It doesn't really taste bitter though =P
