Meh, this is not going to be what you want to hear unfortunately.
By and large you should probably start out with a therapist rather than hormones as those silly hormones can have some very unpleasant side effects for some. Granted it is unlikely you will be part of the percentage that practically drops dead but HRT IS playing with fire, I suggest trying to determine what is what before you worry about HRT in general.
But that said I am really not sure if a herbal thing would give you a clue anyway so I can't really give a yea or nae on that but by and large you can generally get all of the confirmation you need internally, and hence the recommendations of therapists.
This is just how I see things mind. I wish you luck and good fortune, and bid you keep thy brain engaged at all times
