Women often face challenges in their efforts to breast-feed their infants. One of these challenges may be a real or perceived insufficient milk supply. Presented here are some results from a qualitative study of self-care in pregnancy, birth and lactation among a purposeful sample of childbearing women in British Columbia. Twenty-three women were interviewed at one to four months postpartum, and were asked to share their experiences with childbirth and postpartum self-care. Interviews were tape recorded and transcribed. All 23 women were breast-feeding. Four women reported insufficient milk supply, whereas 14 women used galactagogue substances including herbal remedies, food items and pharmaceutical drugs to enhance their milk supply. Eleven women (48% of the sample) were using any of five galactagogue herbs, in many cases prophylactically. Each herb is reviewed and discussed here: blessed thistle (Cnicus benedictus), fennel (Foeniculum vulgare), fenugreek (Trigonella foenicum-graecum) raspberry leaf (Rubus idaeus), and stinging nettle (Urtica dioica). This study reveals that galactagogue herb use is an element of postpartum self-care for some women, and it also identifies a need for clinical testing of the herbs. A larger-scale survey of galactagogue herb use would be beneficial to the state of knowledge, as would clinical trials and case reports on the more popular herbs.
