Introduction

Moxibustion, a traditional Chinese medicine therapy, which involves the burning of mugwort (Artemisia vulgaris) on or near the skin to facilitate healing, has been utilized for thousands of years. It has been applied to treat various ailments, leveraging the heat generated from mugwort to stimulate specific body points. While its usage spans a rich history, modern science has sought to explore and validate the physiological effects moxibustion has on the human body. A recent study published in “Evidence-based Complementary and Alternative Medicine” by Li Ying et al. (2019) investigates the response of local and distal skin temperature to moxibustion stimulation (MS) as well as the effects of MS on sympathetic nerve activity. This in-depth news article delves into the study’s findings and its implications for the broader medical field.

Study Overview

The study (DOI: 10.1155/2019/3185987) conducted by Li and colleagues at the Key Laboratory of Thermo-Fluid Science and Engineering of MOE, Xi’an Jiaotong University, China, aimed to investigate the underlying mechanisms by which moxibustion exerts its effects, particularly in terms of thermal response and its correlation with the sympathetic nervous system.

Methodology

Thirty-six healthy participants were divided into three groups, each receiving MS at either the Quze (PC3) or Lao Gong (PC8) acupoints, with the latter also being tested with an ash cleaning (AC) operation. The fingertip temperatures, indicative of sympathetic reflex responses, were recorded alongside temperatures at the local stimulation points and corresponding control points during a resting period, an MS period, and a natural cooling period, using an infrared camera.

Findings

The results demonstrated a significant and immediate increase in temperature at the local stimulation point at the beginning of the MS period, accompanied by a simultaneous decrease in fingertip temperature. This was suggested to be a manifestation of MS evoking a reflexive sympathetic reaction, leading to a reduction in peripheral blood flow and a subsequent decrease in skin temperature distally.

Moreover, a marked and negative correlation was found between temperature changes at the stimulation point and the fingertips. Throughout the natural cooling period, the impacted skin regions gradually returned to their baseline temperatures. Notably, the practice of AC during MS influenced these thermal changes.

Implications

The findings from Li Ying and team’s study provided important insights into how moxibustion can influence the body’s thermoregulatory processes and the sympathetic nervous system. Their work elucidated that moxibustion, a key component of ancient Chinese medical practice, causes measurable physiological responses and could potentially impact sympathetic-mediated processes.

Applications of Findings

These results have significant implications for the therapeutic application of moxibustion, as it continues to be used in modern alternative medicine. Understanding the physiological mechanisms allows for better-targeted therapies and the potential integration of moxibustion into broader treatment plans. It also opens avenues for exploring its use as a non-invasive option for conditions associated with dysregulation of sympathetic nerve activity.
