Which point is frequently used for regulating and tonifying blood?

The point that is frequently used for regulating and tonifying blood is SP-10, also known as Xuehai (Blood Sea). This point is located on the spleen channel and plays a significant role in blood-related conditions. It is primarily associated with nourishing and regulating blood, making it beneficial for conditions such as blood deficiency, irregular menstruation, and gynecological issues.

SP-10 is often selected for its ability to invigorate blood circulation and help with blood stagnation, which can result in pain or other health issues. It harmonizes the relationship between the spleen and blood, supporting the spleen's function of transporting and transforming nutrients into blood.

In comparison, SP-1 is related to regulating the spleen and generating blood but is primarily known for its role in cases of uterine bleeding. LI-11 is more associated with clearing heat and resolving dampness, making it less relevant for blood tonification. ST-36, while a powerful point for overall vitality and strength, is more focused on qi and digestive functions rather than blood regulation specifically. Therefore, SP-10 is the correct choice for tonifying and regulating blood.
