What is the alternate name of the Heart meridian?

The Heart meridian is indeed known as the Hand Shaoyin. This classification is part of Traditional Chinese Medicine (TCM), where each organ, its corresponding meridian, and its energy pathways are categorized into specific 'meridian systems.' The term "Shaoyin" refers to a specific category of meridians associated with coldness and the Yin aspect, which corresponds closely with the Heart's characteristics in TCM.

The Hand meridians are divided into two categories: Taiyang and Shaoyin. The Taiyang meridians, like those of the Small Intestine and the Bladder, are typically associated with Yang energy. In contrast, the Hand Shaoyin refers specifically to the Heart meridian, emphasizing its Yin qualities like cooling, calming, and nourishing functions within the body.

Understanding this classification helps practitioners in diagnosing and treating various conditions related to the Heart, considering both its physical functions and its role in the body's overall energy systems.
