K-2 is categorized as which type of point?

K-2, or Kidney 2, is categorized as a Ying Spring point. Ying Spring points are located on the channels and are characterized as the second point on a channel following the Jing Well point. They have a specific function in Traditional Chinese Medicine, primarily related to generating fluids, benefiting the heart, and addressing conditions associated with heat and Yin deficiency.

The Ying Spring points are known for their capacity to nourish Yang and clear Heat, which aligns with the characteristics of Kidney 2. This point specifically is often used to help with symptoms such as night sweats, thirst, and problems associated with the Kidneys.

In contrast, Yuan Source points are associated with the source energy of the respective organ and are crucial in tonifying that organ's function. Jing Well points, on the other hand, are located at the beginning of a channel and are used for clearing heat and treating conditions related to the mental state. Shu Stream points have a relationship with the circulation of Qi and are used in the treatment of joint pain and heavy sensations in the body.

Therefore, K-2 is designated as a Ying Spring point because of its specific therapeutic qualities and its position on the channel.
