Er Long Zuo Ci Wan

Log in to view price

Zhenatura Er Long Zuo Ci Wan Extra Strong is a traditional Chinese herbal and mineral preparation formulated according to the principles of Traditional Chinese Medicine (TCM). This classical combination features key ingredients including Rehmannia root (Shu Di Huang), Magnetite (Ci Shi), Bupleurum root (Chai Hu), Cornus fruit (Shan Zhu Yu), and Poria fungus (Fu Ling). These ingredients are traditionally valued for their ability to support clarity in the senses, promote a feeling of inner calm, and maintain a healthy energy balance in the head and ears. Rehmannia (Shu Di Huang) and Cornus (Shan Zhu Yu) are used in TCM to deeply nourish the body’s Yin and support foundational vitality, while the mineral Magnetite (Ci Shi) is traditionally believed to anchor ascending energy and soothe the system. Bupleurum (Chai Hu) assists in maintaining a smooth, clear flow of energy to the upper body. Together, these ingredients help support sensory comfort, emotional grounding, and overall wellbeing.

This product is sold exclusively as a dietary supplement. It is not a medicine. Its use is based on traditional TCM applications.

Main benefits

  • Pattern Identification: Traditionally used for the TCM pattern of Kidney Yin deficiency with ascending Liver Yang, presenting as chronic tinnitus (often described as a high-pitched, cicada-like ringing), gradual hearing loss, dizziness, and a sore lower back.

  • Core Function: The formula is classically said to deeply nourish Kidney and Liver Yin, anchor floating Yang, and open the sensory orifices of the ears.

  • Kidney, Liver, and Ear Relationship: Based on the TCM principle that "the Kidneys open into the ears" and "Liver and Kidney share the same source." When Kidney Yin is depleted, it cannot nourish the ears or control Liver Yang, which then rushes upward to obstruct hearing.

  • Key Ingredients: Shu Di Huang (Prepared Rehmannia) deeply nourishes Kidney Yin and Essence; Ci Shi (Magnetite) provides heavy anchoring to subdue floating Yang and directly treats tinnitus (note: EU standards strictly monitor or substitute mineral ingredients for heavy metal compliance); Chai Hu (Bupleurum) acts as a guiding herb to direct the formula's actions to the Shaoyang channels around the ears; and Shan Zhu Yu (Asiatic Cornelian Cherry) astringes and nourishes Liver and Kidney Yin.

  • Emotional Component (TCM): Ringing in the ears and dizziness often worsen during periods of stress, anger, or exhaustion, reflecting how emotional strain depletes Yin and further triggers the upward flare of Liver Fire/Yang.

  • Region of Action: Specifically targets the inner ear and head for symptom relief, while structurally addressing the lower back and Kidneys as the root cause of the deficiency.

  • Classical Heritage: A widely used modification of the Song-dynasty foundational formula Liu Wei Di Huang Wan, specifically adapted with anchoring and guiding herbs to become the archetypal treatment for age-related or Yin-deficient auditory decline.

Zhenatura Er Long Zuo Ci Wan Extra Strong is based on the classical Er Long Zuo Ci Wan (“Deafness Left-Benefiting Pill”), first recorded in the Ming-dynasty medical text Shou Shi Bao Yuan (“Achieving Longevity by Guarding the Source”) by the renowned physician Gong Ting-xian. Within traditional Chinese herbal literature, this specific combination of ingredients—including Prepared Rehmannia Root, Asiatic Dogwood Fruit, Chinese Yam, Poria Mushroom, Magnetite, and Bupleurum Root—was described as a method to “nourish Kidney Yin,” “subdue Liver Yang,” and “open the orifices” in accordance with the TCM theoretical framework. These descriptions belong exclusively to the traditional conceptual system of Chinese medicine and do not refer to modern anatomy, psychology, or scientifically validated physiological effects.

1
Subjective Tinnitus — Anchoring Rising Yang
https://pmc.ncbi.nlm.nih.gov/articles/PMC9006145/

Please note: This summary is a concise interpretation of the original article; please refer to the source for the full context and details.

The absolute primary clinical application for Er Long Zuo Ci Wan is the treatment of subjective, high-pitched tinnitus (ringing in the ears), particularly in older adults or individuals suffering from chronic stress and burnout.

Clinical studies have demonstrated that Er Long Zuo Ci Wan achieves an overall effective rate of over 80% for subjective tinnitus when taken over a one-month course by patients matching the Yin deficiency pattern. Pre-clinical pharmacological research on rat models of salicylate-induced tinnitus revealed that the formula directly suppresses the abnormal, spontaneous hyper-excitability in the auditory central nucleus of the brain. By tonifying the Yin and using Ci Shi to physically "anchor" the nervous system, the formula reduces the neurological misfiring that causes the patient to hear a constant ringing sound.

Sensorineural Hearing Loss — Nourishing the Ear Orifices
https://www.scienceopen.com/hosted-document?doi=10.15212/npt-2025-0001

Please note: This summary is a concise interpretation of the original article; please refer to the source for the full context and details.

The formula is widely used in integrative medicine to slow the progression of age-related sensorineural hearing loss (presbycusis) and sudden deafness linked to neurological exhaustion.

In TCM, hearing loss that develops gradually and worsens with fatigue is a direct result of the Kidneys failing to nourish the ears. Research suggests that Er Long Zuo Ci Wan possesses distinct "otoprotective" (ear-protecting) properties. By heavily nourishing the Kidney Essence (Shu Di Huang, Shan Zhu Yu), the formula increases microcirculation to the inner ear labyrinth and protects the delicate hair cells in the cochlea from oxidative stress and age-related degradation. The addition of Chai Hu (Bupleurum) acts as a specific "envoy" herb, guiding this increased blood flow directly to the Shao Yang channels surrounding the ear.

Dizziness, Vertigo, and Hypertension — Subduing Liver Fire
https://www.mayway.com/blogs/articles/er-long-zuo-ci-wan-for-tinnitus

Please note: This summary is a concise interpretation of the original article; please refer to the source for the full context and details.

Because the formula excels at pulling "escaped" Yang energy out of the head, it is also highly effective for treating dizziness, vertigo, blurred vision, and high blood pressure associated with Liver Yang Rising.

When Liver Yang flares up, it often causes a feeling of a "heavy head," irritability, and a red face, alongside the ringing ears. The heavy mineral Ci Shi (Magnetite) strongly subdues this Liver Yang, while Mu Dan Pi (Moutan) cools the associated "Liver Fire." This combination rapidly lowers the physical pressure in the head, resolving the dizziness and helping to regulate systemic blood pressure.

For Er Long Zuo Ci Wan, take 3 tablets 2 times per day. These should be taken before or after meal.
