PICO Framework

P — Population104 women with postpartum hypogalactia
I — InterventionHerbal galactagogic decoction combined with auricular acupressure
C — ComparatorAuricular acupressure alone
O — OutcomesBreast milk production, formula supplementation, serum hormone levels (estradiol, progesterone, prolactin), symptom scores, psychological status, clinical effectiveness

Bottom Line

This RCT suggests that combining herbal galactagogic decoction with auricular acupressure may improve lactation outcomes in women with postpartum hypogalactia compared to acupressure alone. The intervention group showed statistically significant improvements in milk production, hormonal profiles, and clinical effectiveness rates. However, the study has significant methodological limitations including unclear randomisation procedures, lack of blinding, and insufficient reporting of effect sizes and confidence intervals. While the intervention appears safe, the evidence quality is moderate at best. Australian clinicians should consider this as preliminary evidence requiring validation in larger, more rigorously designed trials before routine clinical implementation. The intervention may be considered as adjunctive therapy for motivated patients seeking complementary approaches, provided appropriate practitioner expertise is available and conventional lactation support measures are not neglected.

Evidence: Moderate

Key Findings

  • P Value: P<0.05 for between-group differences

  • Effect Size: Not reported

  • Primary Outcome: Increased breast milk production and reduced formula supplementation in intervention group

  • Nnt Or Sensitivity: Overall effectiveness rate 96.15% vs 80.77% (NNT approximately 6.5)

  • Confidence Interval: Not provided

Clinical Application

Requires access to qualified practitioners for auricular acupressure and standardised herbal preparations Complementary medicines require TGA registration; acupressure practitioners need appropriate qualifications. Consider alongside RACGP breastfeeding guidelines and lactation consultant support Postpartum women with documented hypogalactia seeking complementary lactation support

Abstract

Postpartum hypogalactia is a common condition that may impair breastfeeding and maternal-infant health. This randomized controlled study evaluated the efficacy of a herbal galactagogic decoction combined with auricular acupressure in improving lactation outcomes. A total of 104 women with postpartum hypogalactia were enrolled between July 2023 and June 2025 and randomly assigned to a control group (auricular acupressure alone, n=52) or an intervention group (auricular acupressure plus herbal decoction, n=52) for 2 weeks. Primary outcomes included breast milk production and formula supplementation, while secondary outcomes comprised serum hormone levels (estradiol, progesterone, and prolactin), symptom scores, psychological status, and clinical effectiveness. Both groups showed significant post-treatment improvements (P<0.05). Compared with the control group, the intervention group demonstrated lower estradiol and progesterone levels, higher prolactin levels, increased milk production, and reduced formula supplementation (P<0.05). Symptom scores and anxiety/depression levels were also significantly improved. The overall effective rate was higher in the intervention group (96.15% vs 80.77%, P<0.05), with comparable safety profiles. This combined therapy appears to be a safe and effective complementary approach for improving lactation in women with postpartum hypogalactia. L’hypogalactie post-partum est une affection fréquente pouvant compromettre l’allaitement et la santé maternelle et infantile. Cette étude randomisée contrôlée a évalué l’efficacité d’une décoction galactagogue à base de plantes associée à l’acupression auriculaire pour améliorer les résultats de lactation. Au total, 104 femmes atteintes d’hypogalactie post-partum ont été recrutées entre juillet 2023 et juin 2025 et réparties aléatoirement en un groupe témoin (acupression auriculaire seule, n=52) et un groupe intervention (acupression auriculaire associée à une décoction à base de plantes, n=52) pendant 2 semaines. Les critères de jugement principaux comprenaient la production de lait maternel et le volume de supplémentation en lait artificiel, tandis que les critères secondaires incluaient les niveaux hormonaux sériques (estradiol, progestérone et prolactine), les scores symptomatiques, l’état psychologique et l’efficacité clinique. Les deux groupes ont montré des améliorations significatives après le traitement (P<0,05). Comparé au groupe témoin, le groupe intervention présentait des niveaux plus faibles d’estradiol et de progestérone, des niveaux plus élevés de prolactine, une production de lait accrue et une réduction de la supplémentation (P<0,05). Les scores symptomatiques ainsi que les niveaux d’anxiété et de dépression ont également été significativement améliorés. Le taux global d’efficacité était plus élevé dans le groupe intervention (96,15 % vs 80,77 %, P<0,05), sans différence significative en termes d’effets indésirables. Cette thérapie combinée pourrait constituer une approche complémentaire sûre et efficace pour améliorer la lactation chez les femmes présentant une hypogalactie post-partum.
