Acupuncture involves the insertion of fine needles into specific points on the body to balance the flow of Qi. Histological studies have shown that acupuncture can stimulate the release of neurotransmitters and endorphins, which help to reduce pain and inflammation. Additionally, acupuncture may affect the microcirculation of blood, leading to improved tissue oxygenation and nutrient delivery. These changes can be observed in histological samples as increased capillary density and reduced inflammatory cell infiltration.
