THE best healing herb to start as quick as she can is licorice root. I've seen licorice root powder completely heal a severe gastritis caused by too many NSAID meds after several rX scripts didn't touch it.
If it's actually bleeding, your in dangerous territory treating it yourselves. However, yarrow (achillea millefolia) is a powerful yet usually safe astringent herb which can work on bleeding. Shepherds Purse is an even stronger one, often recommended for internal bleeding of all types. Whether or not either of them are available commercially, I can't say.
If the divorce is causing her that much stress, she might want to consider taking some of the nervine herbs- skullcap, passionflower, lemon balm, valerian or kava kava- for awhile. Of them all, I prefer skullcap, but others have different preferences. Most places that sell herbs or alternative health care products have products which are combinations of some of the above list, and they really can make a large difference in the stress level the body is feeling.
Also, because of her stress, she needs to get on a good B Complex vitamin package as soon as possible. Stress absolutely eats the B vitamins, and without adequate levels, the body can't deal with stress- it's a vicious circle.
Hope she's feeling better soon
