Juliet,
One place you might start is with
The Macrobiotic Path to Total Health: A Complete Guide to Preventing and Relieving More Than 200 Chronic Conditions and Disorders Naturally by Michio Kushi and Alex Jack (Ballantine Books)
http://www.qualitynaturalfoods.com/s...345439872.html.
Michio and Alex address a variety of reproductive disorders in that book including endometrial and endometrium on pages 164, and 184 including how to eat and what remedies to take macrobiotically.
Also, Dr. Christiiane Northrup's book
Women’s Bodies, Women’s Wisdom:Creating Physical and Emotional Health and Healing http://www.drnorthrup.com/health_store-cn-lit.php also addresses endometriosis quite extensively.
Both of those books should help you improve your situation, somewhat.
Also, get a ($4.) copy of the May /June 2004
macrobiotics today "Raising Healthy Families" issue (800-232-2372
http://gomf.macrobiotic.net/Newsletter.htm) and read the inteview with Diane Avoli (who has had eight macrobiotic kids and who teaches cooking at the Kushi Institute).
Afterwards you might want to e-mail her with specific questions.
Let us know how things go.
Thank you, very much.
