What symptoms may be alleviated by the point BiZhong?

The point BiZhong, located on the forearm, is primarily used to address symptoms related to the upper extremities. It is particularly effective in alleviating issues such as paralysis or spasm, as well as forearm pain. This association stems from the point’s ability to influence the Qi and blood circulation in the channels that run through the upper limb, making it useful for treating conditions that involve motor dysfunction and pain in that area.

When considering the other options: cholecystitis and cholelithiasis pertain to the gallbladder and digestive issues, which are not within the purview of BiZhong's effects. Similarly, knee pain and weakness of the lower extremities are generally treated with points that are more specifically located in the lower body, and not with an upper extremity point like BiZhong. Lastly, symptoms such as stuffy chest, gastric pain, and hemoptysis are associated with more central or digestive system challenges, which do not align with the primary uses of BiZhong.
