I like the herb based over-the-counter tablets. They work really well for post-menopause, especially hot flashes. I used to get so many hot flashes before I started taking these and it's almost completely gone now.
I actually also tried some herb teas that are said to be natural estrogen. I drank garden sage tea for a while. It did help a little, but it really is hard to control how much estrogen you're getting, so I went back to the tablets.
I've never wanted to take prescription tablets because my doctor said that they are very strong and it's unnecessary in my situation. Over-the-counter tablets are weaker and better for post-menopause symptoms.
