Background
Striae gravidarum is a common skin condition that affects approximately 60–90 % of pregnant women. This systematic review aimed to evaluate the effectiveness of herbal remedies in preventing stretch marks during pregnancy.
Methods
A comprehensive literature search was conducted in PubMed, Cochrane Library, Embase, Scopus, and SID databases for studies published between January 1972 and May 2024. Randomized controlled trials (RCTs) assessing the preventive effects of herbal remedies—including oils, creams, and plant-based extracts—on pregnant women were included. Data were analyzed using RevMan software, and meta-analysis was performed using fixed-effect or random-effects models based on the degree of heterogeneity. Subgroup analysis was performed based on the type of herbal remedies on incidence (primary outcome) and itching and erythema (secondary outcomes).
Results
A total of 12 randomized controlled trials involving 1956 pregnant women were included. Herbal treatments such as Aloe vera gel, sweet almond oil, and sesame oil showed a significant reduction in the incidence of stretch marks compared to placebo (12 studies, n = 1956; OR = 0.47, 95 % CI: 0.28–0.79, p = 0.004). In addition, four subgroup analyses from four distinct studies (n = 601) demonstrated that herbal products significantly reduced the incidence of itching compared to controls (OR = 0.09, 95 % CI: 0.03–0.30, p < 0.00001), while two studies (n = 139) showed a significant reduction in erythema incidence in the intervention groups (OR = 0.17, 95 % CI: 0.07–0.38, p < 0.0001).
Conclusion
Although some herbal remedies, especially Aloe vera, Sweet Almond oil and Sesame oil have high potential for the prevention and management of stretch marks, the heterogeneity in the studies' design and results indicates the need for more high-quality research.
