The liver meridian's connection to physical aspects is primarily seen in which part of the body?

The liver meridian is closely associated with the health and condition of the nails in Traditional Chinese Medicine (TCM). In TCM, the liver is believed to play a vital role in the nourishment and smooth flow of Qi (energy) and blood throughout the body. It is also linked to the sinews and tendons, which can be indirectly connected to nail health.

Nails are thought to reflect the state of the liver and its ability to nourish the body. According to TCM theories, strong, healthy nails indicate an adequate supply of liver blood and Qi, while brittle or unhealthy nails can be a sign of liver deficiency or disharmony. This connection emphasizes the holistic view in TCM where organs are interconnected with various physical aspects, making the nails a clear manifestation of liver health.

Other options, while relevant in their own contexts, are not directly associated with the liver meridian in the same way as nails. For instance, while hair health can be influenced by liver function, nails more specifically reflect its condition in TCM.
