Though formal scientific research on the subject is rather limited, there are a handful of studies that show promising results.
Decreases liver inflammation
Studies suggest Gua Sha reduces chronic inflammation, particularly in the liver in just 48 hours. Researchers speculate that this type of treatment could benefit anyone who suffers from chronic pain, including arthritis.
If you suffer from headaches during pregnancy, one study suggests just 14 days of treatment reduced headache symptoms. Though additional research needs to be done—the study was limited to just one individual—the findings are promising.
Reduces engorgement while breastfeeding
When coupled with proper breastfeeding techniques, studies suggest Gua Sha is more effective at reducing engorgement and discomfort in the immediate postpartum period than massage and hot packs.
Alleviates neck pain
In one study, half of participants used Gua Sha techniques, while the other half used hot packs. The group who received Gua Sha treatments reported significantly less neck pain after just one week.
Reduces symptoms of menopause
Insomnia, fatigue, anxiety, hot flashes—many women suffer from these symptoms during menopause. But in one study, women who received only 15 minutes of Gua Sha treatment a week for eight weeks reported fewer symptoms than women who used conventional therapies.
