red raspberry leaf tea for menstruation, does raspberry itself work

Have read many places that red raspberry leaf tea is good for heavy menstruation. Are raspberries also, or just the leaves? Also, I'm told my period is probably normal, but I think it's too much, and have always been drained during. I try to eat enough vitamins in my food but when bleeding that much feel like I have to start back over n that I've lost too much. Sometimes I do not have enough food to always have proper nutrition, n i do not enjoy feeling like I have to replenish so much because of a period every month. What else would be good for this that is natural? Again, its probably normal, but I think its too much.

I also found out I have worms recently, n I know they leech off of peoples nutrition. That's a separate forum but I can't post this particular post there.
