Googling for this spice will lead to vast informative results. But what I am sharing here is my personal experience with this. I started using menthe in my routine because of my mother. She is a big fan of this and uses it regularly. I have been regularly eating this from past 6 months. I soak 2 spoons of menthe overnight and consume it first in the morning along with the soaked water.  Once I started using this
1. Have seen reduction in hair fall
2. Has reduced my menstrual cramps
3. Has reduced pain in my back and calf
I cant assure that whoever uses it will see benefits the same way as I have but it will help you improve your health in one way or the other.
