I've used Clary Sage. Don't think I noticed a difference but I didn't use it regulary. Haven't tried Ylang Ylang, I'm thinking the reason why was probably the cost.I can help you on that one, I use essential oils. Clary sage helps with hormone balance. It is a phytoestrogen. Ylang ylang also helps to balance out male/female energy. Also get the hormones checked. I use Her Balance Cream, which is a progesterone cream that is used by doctors.
Pepawbear is correct on the cream. I highly recommend reading all of Dr. Lee's books about perimenopause, menopause, and breast cancer. All check out Dr. Christiane Northrup book Women's Bodies, Women's Wisdom, which covers the physical and emotional aspects of women's health.
I've used progesterone cream and that helped, probably second to the Estrovera which is what really worked for me.
