The presented protocol describes a traditional Chinese medicine treatment procedure known for its safety and effectiveness in managing gestational vomiting.

Nausea and vomiting in pregnancy (NVP) are common symptoms that often complicate early pregnancy for many women. While clinical treatments such as fasting, fluid infusion, and nutritional support are conventionally applied to manage NVP, their effectiveness varies. However, traditional ear plaster therapy offers a promising alternative that effectively relieves symptoms and poses no known risk to the development of embryos or fetuses. This therapy is known for its ease of application, cost-effectiveness, and favorable outcomes. Previous studies have demonstrated the efficacy of combining ear plaster therapy with conventional treatments in alleviating symptoms of nausea and vomiting in pregnant women, surpassing the results achieved with conventional treatment alone. The protocol presented herein describes a method to relieve NVP using round, smooth, and hard cowherb seeds applied to specific ear points. These seeds are gently rubbed onto the surface of the ear, utilizing the principles of acupressure. By stimulating the designated ear points, this procedure aims to regulate the body's energy flow and restore balance, thereby reducing the severity and frequency of NVP. The application of cowherb seeds on specific ear points is a straightforward technique that healthcare professionals can easily implement or self-administered by pregnant women under appropriate guidance. Overall, ear plaster therapy presents a safe, effective, and economical approach for managing gestational vomiting, offering women a potential solution to alleviate their discomfort during pregnancy.

Nausea and vomiting during pregnancy (NVP) are common, affecting approximately 50%-80% of pregnant women to varying degrees1. When NVP progresses to moderate or severe levels, it increases the risk of adverse pregnancy outcomes for both the mother and the fetus. Therefore, early intervention for NVP may be beneficial in preventing the development of hyperemesis gravidarum2. The exact cause of NVP is not well understood in modern biomedicine, but it is believed to be associated with factors such as changes in the serum level of human chorionic gonadotropin during pregnancy and deficiencies of certain vitamins22. Consequently, pharmacological treatments come with their own set of dangers. On the other hand, the symptom-centered t.......
