THE REAL PROBLEM

It's Not That Your Body Isn't Healing.

It's that it hasn't been understood.

If you have been dealing with hormone imbalance, fatigue, brain fog, digestive discomfort, or chronic pain, you have probably already tried:

Supplements that didn't work

Diet changes that felt restrictive

Medications that only masked symptoms

In Traditional Chinese Medicine, the same symptom can have entirely different root causes.

Which means the same supplement will not work for everyone. Guessing leads to frustration.

EXPERT GUIDANCE MATTERS

Why You Shouldn't Self-Prescribe Herbs

Chinese herbs are powerful, but only when used correctly. The combination, dosage, and timing all matter. Taking the wrong herbs can:

Worsen an exisitng imbalance rather than correct it

Delay real healing while symptoms shift or supress

Create new symptoms unrelated to the original concern

This is why a proper TCM diagnosis preceeds every custom formula we build. Pattern first, prescription second.

Why Root-Cause Matters

Supplements and medications typically target isolated symptoms with standardized dosing.

Traditional Chinese Medicine treats the whole system

If you have tried eliminating gluten, adding magnesium, cycling through probiotics, or balancing hormones with generic protocols and still do not feel like yourself, the issue is rarely a missing ingredient. It is usually a pattern of imbalance that a one-size-fits-all approach cannot reach.

Traditional Chinese Medicine has been refining this diagnostic framework for over two thousand years. A custom herbal formula combines multiple herbs that work synergistically, and it is adjusted over time as your body responds. It is precise, systematic, and profoundly personal.

That is what we do at Healing with Zen. No guesswork. No generic protocols. Just personalized, root-cause care.

Common Questions

The questions patients ask most often before their first consultation.

What is a custom Chinese herbal formula?

A custom Chinese herbal formula is a personalized prescription of medicinal herbs selected by a trained Traditional Chinese Medicine practitioner to address your specific pattern of imbalance. Unlike pre-packaged supplements, each formula is tailored to your individual symptoms, constitution, root cause, and is adjusted over time as your body responds.

How is Traditional Chinese Medicine different from supplements or medication?

Supplements and medications typically target isolated symptoms with standardized dosing. Traditional Chinese Medicine identifies the underlying pattern causing symptoms, such as Liver Qi stagnation, Kidney Yin deficiency, or Spleen Qi deficiency, and treats the whole system. Herbal formulas combine multiple herbs that work synergistically, and they are refined as your condition changes.

Why shouldn't I self-prescribe herbs?

Chinese herbs are powerful but only work correctly when matched to your specific TCM pattern. Taking the wrong herbs can worsen existing imbalances, delay healing, and create new symptoms. In Chinese Medicine, the combination of herbs, dosage, and timing all matter, which is why practitioner guidance is essential.

What happens on the 15-minute discovery call vs the herbal consultation?

On the free 15-minute discovery call, we can answer general questions about herbs and how herbal therapy works. We will not be able to discuss your main symptoms or identify potential root imbalances, as this is done during the full herbal consultation that can last between 30 to 45 minutes. There is no pressure to commit to treatment by scheduling a 15-minutes discovery call.

Who is Zen Tuan, L.A.c.?

Zen Tuan, L.A.c. is the owner, founder, and Clinical Director of Healing with Zen in Pasadena, California. She is a California board certified physician of Acupuncture and Traditional Chinese Medicine, holds a Masters Degree from Emperor's College, and a Bachelor of Science from UC San Diego. She has served the Pasadena, San Gabriel and Los Angeles community since 2013.

What conditions can Chinese herbal medicine help with?

Chinese herbal medicine is commonly used to support a wide array of health issues, ranging from hormone imbalance (PMS, fertility issues, and menopause symptoms) to chronic fatigue and low energy; brain fog and poor concentration; digestive issues such as bloating, IBS, and food sensitivities; and chronic pain and inflammation. Results vary by individual and are strongest when paired with ongoing practitioner guidance. Check out more common conditions we treat by clicking here.

How long does it take to see results from Chinese herbs?

Most patients notice initial shifts within two to four weeks, with deeper constitutional changes taking 3 to 6 months. Acute conditions often respond faster than chronic patterns. Formulas are typically reviewed every 2 to 4 weeks and adjusted based on your progress.

Do I need to come in person to get a custom formula?

No. Healing With Zen offers virtual consultations for custom herbal formulas. After an intake conversation and review of your health history, your formula is shipped directly to you. In-person visits are available at our Pasadena clinic for patients who also want acupuncture.
