The health benefits of drinking red raspberry leaf tea are numerous. The main one for women is to do with the menstrual cycle. The leaves contain lots of potassium, magnesium and iron along with vitamins B, C  and E. It can help with balancing hormones, stopping cramps and just helping balance general well being. 
I have been drinking this tea once a day for a month and I actually do feel different. I am less tired, have more energy, my cravings are less at that time of the month and my premenstrual tension seems less.
Men can drink this too. For men it is supposed to help with testosterone production as well as a boost in vitamins and minerals. 

I pick my own raspberry leaves and use them in tea but you can buy them. I dry them and crush them for winter use or pick fresh and use.

I use a ball tea holder. Place about a teaspoon of leaves in the ball. Steep in boiling water for 5 mins. Add honey or another sweetener of your choice to taste.

I use:
 2 chamomile flowers
2 large leaves chopped
2 dried raspberries
Stevia to sweeten

Warning:I am not a doctor, so my advice is speak to your doctor before taking this tea.
