Which point is classified as a Jing River point and related to fire?

The correct choice is GB-38, which is classified as a Jing River point associated with the fire element. Jing River points are located on theYang channels and generally relate to the transformation of energy, impacting internal organs and physiological functions.

In the context of the Gallbladder channel, GB-38 is positioned on the leg and is known for its ability to influence conditions related to the Gallbladder and liver, as well as broader systemic effects associated with fire energy, such as regulation of warmth, excitement, or even irritability. In traditional Chinese medicine, fire is linked to aspects of heat, spirit, and the capacity for transformation. Therefore, GB-38's association with fire helps practitioners utilize this point for conditions that relate to excess heat or fire.

The other points listed do not fit the criteria. GB-39 is a Hui-Meeting point related to the marrow and is not specifically classified as Jing River. GB-40 serves as a Source point, which has different therapeutic implications. Liv-2 is a Ying Spring point, corresponding with the water element instead. Each point’s classification within the system of acupuncture holds a specific relevance to its therapeutic applications, and understanding these distinctions helps in selecting appropriate points for treatment.
