Enhancing Vagal Tone, Modulating Heart Rate Variability with Auricular Acupressure at Point Zero: A Randomized Controlled Trial.

Introduction: Point Zero located within the vagus nerve's auricular branch shows promise in addressing imbalances. This study aims to explore its effects on vagal activity using auricular acupressure (AA), measured through heart rate variability (HRV).

Methods: This single-blinded randomized controlled trial involved 114 healthy volunteers randomly assigned to receive AA (AA group, = 57) or sham-AA (SA group, = 57) at Point Zero.

Efficacy of Shen Cao Gan Jiang Tang on Non-severe COVID-19 Patients: A Multicenter, Randomized, Open-Label Clinical Trial.

Background In the face of the escalating COVID-19 pandemic amid shortages of medications and vaccines, a Vietnamese herbal formula known as Shen Cao Gan Jiang Tang (SCGJT) has been put into use for non-severe COVID-19 patients. This study aims to assess its efficacy and safety. Methods A multicenter, open-label, randomized controlled trial was conducted on 300 patients with non-severe COVID-19, randomly assigned into two groups: 150 receiving standard care (control group) and 150 receiving additional SCGJT for 10 days (SCGJT group).

Adding thread-embedding acupuncture to auricular acupuncture enhances short-term weight reduction in overweight and obesity: A double-blinded, randomized, sham-controlled trial.

Background: Auricular acupuncture (AA) has been widely used in overweight and obesity management due to its safety and effectiveness. The combination of other acupuncture therapies with thread-embedding acupuncture (TEA) has shown enhanced effects. However, there is a lack of evidence regarding AA plus TEA for overweight and obesity.

Auricular Acupuncture Prior to Menstruation Can Reduce Primary Dysmenorrhea: A Randomized Controlled Trial.

Objective: Primary dysmenorrhea is a common condition that impacts quality of life significantly. Auricular therapies have shown promise for treating primary dysmenorrhea, but there is a lack of evidence specifically for auricular acupuncture (AA). This study evaluated the safety and efficacy of AA for managing primary dysmenorrhea.

Change in Skin Surface Temperature at the Posterior Neck When Using Acupuncture at Houxi Acupoint in Healthy Volunteers.

Introduction The use of acupuncture has been suggested for the treatment of neck pain. Recently, a large body of evidence demonstrated that acupuncture has an effect on microcirculation in pain regions, but the exact mechanism remains unclear. This study aims to evaluate the skin surface thermographic changes in the posterior neck associated with manual acupuncture at the Houxi (SI-3) acupoint.

Thread-embedding acupuncture may improve symptom resolution in patients with gastroesophageal reflux disease: A randomized controlled trial.

Background: Various traditional medicine treatments have been investigated to treat GERD. Among those, thread-embedding acupuncture (TEA) has the advantage that patients need to undergo the procedure infrequently; however, its efficacy is unclear. This study evaluated the efficacy of TEA in treating GERD.

Heart rate variability during auricular acupressure at the left sympathetic point on healthy volunteers: a pilot study.

Introduction: This research is a pilot, single-blinded study investigating heart rate variability (HRV) during auricular acupressure at the left sympathetic point (AH7) in healthy volunteers.

Methods: There were 120 healthy volunteers with hemodynamic indexes (heart rate, blood pressure) within normal ranges, randomly divided into two groups AG and SG (in each group having a gender ratio 1:1, aged 20-29), to receive either auricular acupressure using ear seed (AG) or sham method using adhesive patches without seed (SG) at the left sympathetic point while lying in a supine position. Acupressure intervention lasted 25 min, and HRV was recorded by a photoplethysmography device-namely, Kyto HRM-2511B and Elite appliance.

Auricular Acupressure Effect on Autonomic Responses Evoked by a Cold Pressor Test in Healthy Volunteers: A Pilot Study.

Objective: This pilot study was conducted to investigate changes in the pulse rate and blood pressure in healthy volunteers after applying auricular acupressure at the "heart acupoint."

Methods: A total of 120 healthy volunteers with hemodynamic indexes within normal limits were randomly allocated into 4 groups to receive auricular acupressure treatment either at the heart acupoint of the left or the right, or in both ears, and one control group without applying auricular acupressure.

Results: Before the application of auricular acupressure, there were no statistical differences in pulse rate and blood pressure increments among the four groups during the first cold pressor test.

Heart Rate Variability during Auricular Acupressure at Heart Point in Healthy Volunteers: A Pilot Study.

Heart rate variability (HRV) is the variation in time between each heartbeat. Increasing HRV may contribute to improving autonomic nervous system dysfunctions. Acupuncture stimulation through the vagus plexus in the ear is considered as a method that can improve HRV.
