Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
COPD group
This group will include 40 patients with chronic obstructive pulmonary disease (COPD).
Laser doppler
A laser doppler flowmetry will be used to measure the microcirculatory characteristics of meridian phenomena. The probes will be left at relevant measuring sites. Blood flow curve and Perfusion units (PU ) will be recorded constantly.
1. Healthy control group and COPD group The probes will be left at Shenmen (HT7) and Shaohai (HT3) of the Heart meridian, Taiyuan (LU9) and Chize (LU5) of the Lung meridian for 5 minutes.
2. Healthy intervention group Two sessions of moxibustion will be performed in the Heart meridian and Lung meridian successively.
Healthy control group
This group will include 40 healthy volunteers.

Healthy intervention group
This group will include 40 healthy volunteers. Two sessions of moxibustion intervention will be performed in the Heart meridian and Lung meridian successively. The washout period between the two sessions is at least one day.
