BACKGROUND
Engorgement is the overfilling of breasts with milk, often occurring in the early days postpartum. It results in swollen, hard, painful breasts and may lead to premature cessation of breastfeeding, decreased milk production, cracked nipples and mastitis. Various treatments have been studied but little consistent evidence has been found on effective interventions.
OBJECTIVES
To determine the effectiveness and safety of different treatments for engorgement in breastfeeding women.
SEARCH METHODS
On 2 October 2019, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP), and reference lists of retrieved studies.
SELECTION CRITERIA
All types of randomised controlled trials and all forms of treatment for breast engorgement were eligible.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for eligibility, extracted data, conducted 'Risk of bias' assessment and assessed the certainty of evidence using GRADE.
MAIN RESULTS
For this udpate, we included 21 studies (2170 women randomised) conducted in a variety of settings. Six studies used individual breasts as the unit of analysis. Trials examined a range of interventions: cabbage leaves, various herbal compresses (ginger, cactus and aloe, hollyhock), massage (manual, electromechanical, Oketani), acupuncture, ultrasound, acupressure, scraping therapy, cold packs, and medical treatments (serrapeptase, protease, oxytocin). Due to heterogeneity, meta-analysis was not possible and data were reported from single trials. Certainty of evidence was downgraded for limitations in study design, imprecision and for inconsistency of effects. We report here findings from key comparisons. Cabbage leaf treatments compared to control For breast pain, cold cabbage leaves may be more effective than routine care (mean difference (MD) -1.03 points on 0-10 visual analogue scale (VAS), 95% confidence intervals (CI) -1.53 to -0.53; 152 women; very low-certainty evidence) or cold gel packs (-0.63 VAS points, 95% CI -1.09 to -0.17; 152 women; very low-certainty evidence), although the evidence is very uncertain. We are uncertain about cold cabbage leaves compared to room temperature cabbage leaves, room temperature cabbage leaves compared to hot water bag, and cabbage leaf extract cream compared to placebo cream because the CIs were wide and included no effect. For breast hardness, cold cabbage leaves may be more effective than routine care (MD -0.58 VAS points, 95% CI -0.82 to -0.34; 152 women; low-certainty evidence). We are uncertain about cold cabbage leaves compared to cold gel packs because the CIs were wide and included no effect. For breast engorgement, room temperature cabbage leaves may be more effective than a hot water bag (MD -1.16 points on 1-6 scale, 95% CI -1.36 to -0.96; 63 women; very low-certainty evidence). We are uncertain about cabbage leaf extract cream compared to placebo cream because the CIs were wide and included no effect. More women were satisfied with cold cabbage leaves than with routine care (risk ratio (RR) 1.42, 95% CI 1.22 to 1.64; 152 women; low certainty), or with cold gel packs (RR 1.23, 95% CI 1.10 to 1.38; 152 women; low-certainty evidence). We are uncertain if women breastfeed longer following treatment with cold cabbage leaves than routine care because CIs were wide and included no effect. Breast swelling and adverse events were not reported. Compress treatments compared to control For breast pain, herbal compress may be more effective than hot compress (MD -1.80 VAS points, 95% CI -2.07 to -1.53; 500 women; low-certainty evidence). Massage therapy plus cactus and aloe compress may be more effective than massage therapy alone (MD -1.27 VAS points, 95% CI -1.75 to -0.79; 100 women; low-certainty evidence). In a comparison of cactus and aloe compress to massage therapy, the CIs were wide and included no effect. For breast hardness, cactus and aloe cold compress may be more effective than massage (RR 0.66, 95% CI 0.51 to 0.87; 102 women; low-certainty evidence). Massage plus cactus and aloe cold compress may reduce the risk of breast hardness compared to massage alone (RR 0.38, 95% CI 0.25 to 0.58; 100 women; low-certainty evidence). We are uncertain about the effects of compress treatments on breast engorgement and cessation of breastfeeding because the certainty of evidence was very low. Among women receiving herbal compress treatment, 2/250 experienced skin irritation compared to 0/250 in the hot compress group (moderate-certainty evidence). Breast swelling and women's opinion of treatment were not reported. Medical treatments compared to placebo Protease may reduce breast pain (RR 0.17, 95% CI 0.04, 0.74; low-certainty evidence; 59 women) and breast swelling (RR 0.34, 95% CI 0.15 to 0.79; 59 women; low-certainty evidence), whereas serrapeptase may reduce the risk of engorgement compared to placebo (RR 0.36, 95% CI 0.14 to 0.88; 59 women; low-certainty evidence). We are uncertain if serrapeptase reduces breast pain or swelling, or if oxytocin reduces breast engorgement compared to placebo, because the CIs were wide and included no effect. No women experienced adverse events in any of the groups receiving serrapeptase, protease or placebo (low-certainty evidence). Breast induration/hardness, women's opinion of treatment and breastfeeding cessation were not reported. Cold gel packs compared to control For breast pain, we are uncertain about the effectiveness of cold gel packs compared to control treatments because the certainty of evidence was very low. For breast hardness, cold gel packs may be more effective than routine care (MD -0.34 points on 1-6 scale, 95% CI -0.60 to -0.08; 151 women; low-certainty evidence). It is uncertain if women breastfeed longer following cold gel pack treatment compared to routine care because the CIs were wide and included no effect. There may be little difference in women's satisfaction with cold gel packs compared to routine care (RR 1.17, 95% CI 0.97 to 1.40; 151 women; low-certainty evidence). Breast swelling, engorgement and adverse events were not reported.
AUTHORS' CONCLUSIONS
Although some interventions may be promising for the treatment of breast engorgement, such as cabbage leaves, cold gel packs, herbal compresses, and massage, the certainty of evidence is low and we cannot draw robust conclusions about their true effects. Future trials should aim to include larger sample sizes, using women - not individual breasts - as units of analysis.

Review
Cyclic mastalgia is one of the most prevalent problems in women of reproductive age and sometimes it is so severe that it influences their activities and requires treatment. The available drug treatments for mastalgia are not satisfactory and most patients have inclined towards complementary and alternative medicine including herbal medicines. Therefore, in order to evaluate the effectiveness and side effects of herbal medicines conducting systematic review studies and meta-analysis seems essential, thus this systematic review was conducted with the aim of determining the effect of herbal medicines on cyclic mastalgia and its probable side effects. The databases of Pubmed, Medline, Embase, ProQuest, Scopus, Web of science, Complementary Medicine Database, SID (Scientific information database), Magiran and Iranmedex were searched from 1997 to 2020 and limited only for English and Persian languages. The studies were appraised according to the Cochrane Collaboration's tool. Meta-analysis was conducted using RevMan software. Standardized mean difference (SMD) was calculated to assess an overall estimate of effectiveness for the continuous data. Odds ratio (OR) was calculated for dichotomous data. Thirty papers were included in the study. Meta-analysis of data demonstrated that herbal medicine was an effective method in reducing the severity of mastalgia compared to the placebo (SMD: -3.26, 95% CI: -5.05 to -1.46, p=0.00004). Subanalysis of data showed no difference between the effectiveness of herbal medicine on the severity of mastalgia compared to the pharmacologic treatment. This research demonstrated efficacy of herbal medicines in alleviating cyclic mastalgia. Therefore, these herbal medicines can be regarded as an alternative treatment for women suffering from cyclic mastalgia. However, due to the limited number of studies in relation to each specific herbal treatment, conducting further studies in this area is recommended.

Meta-Analysis Review
Mastalgia, or breast pain, is common among women which can lead to significant impairment in daily living. Hence, finding an effective treatment that can alleviate the symptom is very important. Thus, we carry out this study to determine the efficacy of evening primrose oil (EPO) for mastalgia treatment in women. The review included published randomised clinical trials that evaluated EPO used for treating mastalgia against a placebo or other treatments, irrespective of the blinding procedure, publication status, or sample size. Two independent authors screened the titles and abstracts of the identified trials; full texts of relevant trials were evaluated for eligibility. Two reviewers independently extracted data on the methods, interventions, outcomes, and risk of bias. The random-effects model was used for estimating the risk ratios and mean differences with 95% confidence intervals. Thirteen trials with 1752 randomised patients were included. The results showed that EPO has no difference to reduce breast pain compared to topical NSAIDS, danazol, or vitamin E. The number of patients who achieved pain relief was no different compared to the placebo or other treatments. The EPO does not increase adverse events, such as nausea, abdominal bloating, headache or giddiness, increase weight gain, and altered taste compared to a placebo or other treatments. EPO is a safe medication with similar efficacy for pain control in women with mastalgia compared to a placebo, topical NSAIDS, danazol, or vitamin E.

Meta-Analysis
BACKGROUND
Hyperplasia of the mammary glands (HMG) is the most prevalent breast disease and can become malignant if left untreated. Although "Sancai therapy" has been widely used to treat HMG, its efficacy has not yet been systematically reviewed. This study aims to systematically evaluate the clinical efficacy of Sancai therapy for HMG treatment and provide a clinical basis for its future use.
METHODS
PubMed, Cochrane Library, Web of Science, EMBASE, CNKI, CBM, VIP, and Wanfang databases were reviewed for related data collection. Chinese and English databases were searched for randomized controlled trials on Sancai therapy for HMG. The retrieval date was February 27, 2023. Exclusion criteria: (1) Non-HMG patients; (2) case reports, literature reviews, animal experiments, systematic reviews; and (3) full text could not be obtained. Data obtained after literature screening were imported into the RevMan 5.4.1 software for meta-analysis, and the included literature was assessed for methodological quality using the "bias risk assessment" tool within the software.
RESULTS
The meta-analysis included 11 studies. Compared to the control group, the Sancai therapy treatment group exhibited an overall increased efficacy (relative risk = 1.36, 95% confidence interval [CI] [1.18, 1.58], P < .0001), an increased cure rate (relative risk = 3.74, 95% CI [1.70, 8.25], P = .001), a significant improvement in breast pain (standard mean difference = -2.68, 95% CI [-3.41, -1.96], P < .00001), and a reduction in breast masses (standard mean difference = -2.87, 95% CI [-3.75, -1.99], P < .00001).
CONCLUSION
Sancai therapy significantly improved the overall efficacy, cure rate, and breast pain and reduced breast mass compared with the control groups. However, further large-sample, high-quality, double-blind randomized controlled trials are required to increase the level of evidence.

Meta-Analysis
OBJECTIVE
Different drugs are used to treat mastalgia, such as danazol and bromocriptine, and both are associated with side effects, due to which most of women and healthcare providers are interested in herbal medicines. Therefore we aim to study the effectiveness of phytoestrogens on the severity of cyclic mastalgia.
METHODS
To carry out the present study, English electronic resources such as the Cochrane Library, ISI Web of Science, Scopus, and PubMed were used systematically and with no time limitation up to February 10, 2020.
RESULTS
In total, 20 studies were included in the present meta-analysis. The results of the meta-analysis showed that herbal medicines versus the control group (standard mean difference [SMD] = - 0.585; 95% confidence interval [CI]: - 0.728-- 0.44; heterogeneity; = 0.02; I2 = 42%), herbal medicines versus the B group (SMD = - 0.59; 95%CI: - 0.75-- 0.44; heterogeneity; = 0.03; I2 = 42%), and its subgroups, such as phytoestrogen (SMD = - 0.691; 95%CI: - 0.82-- 0.55; heterogeneity; = 0.669; I2 = 0%), Vitex-agnus-castus (SMD = - 0.642; 95%CI: - 0.84-- 0.44; < 0.001; = 203; I2 = 32%), flaxseed (SMD = - 0.63; 95%CI: - 0.901-- 0.367; = 0.871; I2 = 0%), and evening primrose (SMD= - 0.485; 95%CI:- 0.84-- 0.12; = 0.008; heterogeneity; = 0.06; I2 = 56%] may have effective and helpful effects on improving cyclic breast mastalgia. Also, chamomile, isoflavone, cinnamon, and nigella sativa significantly reduced mastalgia symptoms.
CONCLUSION
Herbal medicines and their subgroups may have effective and helpful effects on improving cyclic breast mastalgia. The findings of our meta-analysis must be done cautiously because low methodological quality in some evaluated studies of this systematic review.
