Hi, I am a Chinese medical herbalist. Ginseng is very powerful. Like a lot of medicines it should be prescribed according to the individual person's issues and constitution. Ginseng has a powerful warming property, strengthens the immune system, stimulates energy but also calms the nervous system.
It's great for women who tend to have lower BBT's, sluggish Luteal phase temps that don't "hold up" or women who have pre AF spotting and women who feel nervy and anxious that also feel cold easily do well with ginseng as do women who get lower backache and feel cold.
Women who have "warm blood" indicated by acne, red skin blemishes, sensitive to chilli peppers who feel bad tempered easily and who have higher BBT's should only take ginseng if they are advised to do so IMO.
