Lv 4, also known as Zhongfeng (中封) and translated as Mound Center, is a crucial acupuncture point located on the Liver meridian. Its strategic position on the dorsum of the foot, between SP 5 (Shangqiu) and ST 41 (Jiexi), in the depression on the medial side of the tendon of the tibialis anterior muscle, makes it a potent point for addressing a wide range of conditions, particularly those related to Liver function and meridian imbalances. Understanding the anatomical location, energetic properties, and clinical applications of Zhongfeng is essential for practitioners of Traditional Chinese Medicine (TCM) and can provide valuable insights for individuals seeking holistic health solutions.

This article will delve into the multifaceted aspects of Lv 4, exploring its precise location, its relationship to the Liver meridian, its indications for various conditions, and its connection to broader patterns of disharmony within the body. We will also discuss how it relates to other acupuncture points and patterns, particularly in the context of kidney yang deficiency, liver blood deficiency, spleen yang deficiency, liver qi stagnation, liver yin deficiency, and kidney yin deficiency. By providing a comprehensive overview of Zhongfeng, this article aims to equip practitioners and patients alike with a deeper understanding of this valuable acupuncture point.

I. Anatomical Location and Identification of Zhongfeng (Lv 4)

The precise location of Lv 4 is paramount for accurate needling and effective treatment. It is found on the dorsum of the foot, which is the upper surface of the foot. To locate it accurately:

1. Identify SP 5 (Shangqiu): This point is located anterior and inferior to the medial malleolus (the bony prominence on the inner side of the ankle).

2. Identify ST 41 (Jiexi): This point is located in the depression between the tendons of the extensor hallucis longus and extensor digitorum longus muscles on the anterior aspect of the ankle joint.

3. Palpate the Tibialis Anterior Tendon: This tendon runs along the front of the lower leg and crosses the ankle joint to insert on the medial side of the foot.

4. Locate the Depression: Zhongfeng (Lv 4) is situated in the depression on the medial (inner) side of the tibialis anterior tendon, approximately midway between SP 5 and ST 41.

Precise palpation is key to accurately locating this point. The depression may be subtle, requiring careful attention to anatomical landmarks. Once located, the area may be slightly tender to the touch.

II. Energetic Properties and Functions of Zhongfeng (Lv 4)

In TCM theory, each acupuncture point possesses unique energetic properties and functions that contribute to the overall balance of the body. Zhongfeng, as the Jing-River point of the Liver meridian, plays a significant role in regulating the flow of Qi and Blood within the meridian and influencing the functions associated with the Liver organ system.

* Jing-River Point: Jing-River points are located where the Qi of the meridian begins to flow more deeply into the body. They are traditionally used to treat conditions that affect the joints and sinews, as well as diseases that manifest with a change in voice. In the context of Zhongfeng, this suggests its efficacy in addressing musculoskeletal issues of the foot and ankle, as well as conditions affecting the voice that may be related to Liver Qi stagnation.

* Regulates Liver Qi: The Liver is responsible for the smooth flow of Qi throughout the body. When Liver Qi stagnates, it can lead to a variety of symptoms, including irritability, frustration, distension, pain, and menstrual irregularities in women. Zhongfeng helps to smooth and regulate Liver Qi, alleviating these symptoms and promoting emotional well-being.

* Benefits the Sinews and Bones: The Liver in TCM is said to govern the sinews and tendons. Liver Blood nourishes and moistens these tissues, allowing for proper movement and flexibility. Zhongfeng can be used to strengthen the sinews and bones of the foot and ankle, treating conditions such as sprains, strains, and arthritis.

* Clears Damp-Heat: The Liver meridian traverses the lower abdomen and can be susceptible to damp-heat accumulation. Zhongfeng can help to clear damp-heat from the Liver meridian, addressing symptoms such as jaundice, genital itching, and difficult urination.

* Calms the Spirit (Shen): The Liver is associated with the Hun, which is the ethereal soul and a component of the Shen (spirit). Liver disharmony can disrupt the Shen, leading to anxiety, insomnia, and emotional instability. By regulating Liver Qi and Blood, Zhongfeng can help to calm the Shen and promote mental clarity and emotional balance.
