Alternatives To Hormonal Therapy During The Perimenopause

Abstract

Two types of phyto-estrogens are available from food sources; isoflavones and lignons. Isoflavones are present in legumes, particularly soy, whereas grains and seeds contain lignons. These phyto-estrogens exhibit physiological effects and have been investigated for their potential usefulness in chronic disease, atherosclerosis, and cancer.Ingestion of soy protein, flax seed, and clover has had varying effects on FSH and LH level, luteal phase length, hot flushes, and vaginal epithelial proliferation. Herbal products have been used for centuries and are frequently recommended to relieve perimenopausal symptoms. Many herbals have ingredients with therapeutic effects while others experience only anecdotal success and tend to be exploited by the industry. The safety and efficacy of these products depends upon many factors. In Canada, the Health Protection Branch of Health Canada has been working on revision of existing legislation in order to adapt regulations to this product classification.Health care professionals must not blindly accept or reject alternative remedies but must be open-minded enough to evaluate critically the use of foods and plant medicines during the perimenopausal period.
