Dr. Na Herbal Formulas

1. Why Do We Need Herbal Medicine?

Modern medicine has performed miracles in acute care and emergency medicine. However, for complex, long-term chronic diseases, it often focuses on managing isolated symptoms rather than addressing the root cause of the illness.

Chinese herbal medicine is a sophisticated clinical system refined over thousands of years. It offers a different path: instead of simply suppressing a symptom, herbal formulas work to promote the body's overall functional balance and enhance its innate capacity to heal and regenerate.

For over 40 years of clinical practice in both China and the United States, Dr. Na Zhai recognized that differences in diet, lifestyle, and stress levels between cultures significantly affect health and healing. She realized that the American disease profile is fundamentally different from the Chinese profile. This led her to develop and adapt her herbal formulas specifically to aid the wellness of American patients, delivering fast-acting, consistent, and noticeable results.

2. What is Dr. Na's Herbal System?

Dr. Na's formulas are not over-the-counter supplements. They are clinical tools designed to work together with acupuncture as part of her two synchronized protocols: clearing metabolic waste and awakening the body's healing systems.

A Story Behind Each Formula
Every formula in Dr. Na's system has a story. Each one was created to help a specific patient who had run out of options. They are the distilled experience of thousands of patient encounters. Over the decades, these formulas have been refined, standardized, and proven in clinical practice.

Practitioner-Distributed: To ensure appropriate use, Zhai Scientific products are distributed exclusively through licensed healthcare practitioners and to patients under the care of Dr. Na Zhai.

3. Key Formulas

Below are some of the most widely used Dr. Na’s herbal formulas in her clinical practice. Each one is the result of years of refinement and clinical validation.

#25 Body Clean — The Starting Protocol

Body Clean is the foundational formula in Dr. Na's system. Every patient begins with it, regardless of their illnesses. It is designed to clear accumulated metabolic waste from the colon—waste that has built up over years that creates systemic inflammation throughout the body.

How Body Clean Works Without Being a Laxative:
Body Clean is not a laxative. It was designed for a patient with 30 years of severe diarrhea. A laxative forces the bowel to move artificially. Body Clean, on the other hand, restores normal bowel function by gently breaking down the waste, loosening it so it can be released naturally, while repairing the wall of the colon. It helps the colon do what it was designed to do.

#36 Serenity — For Calm, Sleep, and Mood

Serenity was created for patients suffering from stress, anxiety, depression, and insomnia. It calms the mind, improves sleep quality, and restores emotional balance. Many patients report feeling more relaxed and rested after just a few days. It was born from patients who were on heavy anti-depression and anti-anxiety medications, many of whom successfully reduced—and then stopped—their medication.

#16-1 Intestinal Clean — For Stubborn Constipation

This formula is specifically formulated to address stubborn constipation, particularly in frail elderly patients with qi deficiency, as well as individuals with severe cardiovascular conditions. By preventing excessive straining during bowel movements, it helps reduce the risk of triggering related adverse events. Unlike #25 Body Clean—which targets systemic inflammation—this formulation focuses on clearing stasis and promoting blood flow.

#8 Kidney (Yang) Tonic — For Fatigue and Hormonal Balance

Kidney Tonic strengthens kidney function, which in TCM governs energy, water metabolism, and hormonal balance. It is used for patients with chronic fatigue, hypothyroidism, edema, and other conditions related to kidney deficiency. (Born from a patient who suffered from severe hot flashes for over a year—after treatment that included Kidney Tonic, her symptoms were 90–95% better).

#23 Urinary Controller — For Bladder Control

Urinary Controller supports bladder function and helps restore control. It is used for patients with incontinence and related urinary issues, offering a natural alternative to medication.

#20 Sinus Opener — For Sinusitis and Congestion

Sinus Opener targets chronic sinusitis, nasal congestion, and related respiratory issues. It is often used alongside Body Clean when the lungs and colon are involved—based on the TCM principle that the lungs and large intestine are interior-exteriorly related.

#18-3 Cough Stop — For Cough and Lung Congestion

Cough Stop resolves phlegm and coughing problems that emanate from the lungs. It is often prescribed when a cough persists even after the foundation has been laid with Body Clean and acupuncture.

#28-1 Pain Reliever — For Pain and Circulation

Pain Reliever is designed to restore circulation and resolve pain that has persisted after years of stagnation. It is often used in combination with Body Clean for patients with chronic pain and inflammatory conditions.

Customized Formulas

While these core formulas form the foundation of the system, effective treatment for chronic conditions often requires a personalized approach. Dr. Na frequently creates customized herbal regimens that last from three to six months. This timeline aligns with the body's natural regeneration cycle. By working in harmony with your body's own rhythm, herbal medicine promotes deep healing and fosters lasting well-being.

They are prescribed as part of a comprehensive treatment plan under the supervision of Dr. Na Zhai or a licensed practitioner trained in her system.
