Dr. Karchmer on Four Substance

“A women’s monthly cycle is draining - literally.  Pregnancy, childbirth and breastfeeding are even more demanding on the body.  In our rush to succeed to school, careers and social horizons of our modern world, it is also possible to not full appreciate the unique physiology of women related to menstruation.  Indeed, some women may find their period a hassle, a needless interruption to the schedule, a problem to be managed pharmacologically - there’s where Four Substance can make an incredible difference.”
