During my first day of clinical placement, I shadowed Prof Yang Lu at the Acupuncture Department of Nanfang Hospital (1). His specialised areas include bloodletting therapy, auricular acupuncture, and embedding needle therapy for the treatment of neck, shoulder, lower back, and leg pain, Bell’s palsy, stroke rehabilitation, neurological disorders, and internal conditions such as asthma, vertigo, stomach pain, constipation, and obesity. Although the time was limited, the knowledge I gained from him was extremely valuable.
The Acupuncture Clinic was always fully packed and busy. I remember one morning when around 20 patients were queuing outside the treatment room waiting to be seen. The room contained 10 treatment beds, six electroacupuncture devices, TDP lamps, and three fully equipped trolleys containing various TCM tools. It was a simple medical setting, yet it consistently delivered effective care, as each professor had unique techniques and approaches to treating patients efficiently and successfully.
During my clinical practice, I encountered a wide range of conditions, including Cervical Spondylosis, Sciatica, Bell’s Palsy (BP), post-stroke symptoms, Parkinson’s Disease, cataracts, and emotional disorders. However, the most unforgettable case was a four year-old girl suffering from Bell’s Palsy. She was not the only patient with this condition; even among the adults, around six out of fifteen patients that morning were receiving treatment for Bell’s Palsy.
Honestly, I had never imagined that Bell’s Palsy could occur at such a young age. During the case discussion, Professor Yang explained that in younger patients, the condition is often associated with flu-like infections affecting the ear region.
From a TCM perspective, Bell’s Palsy is often categorised under 'Wind-Stroke' or 'Deviation of the Mouth and Eye'. When it appears after a viral illness, such as herpes simplex, shingles/Ramsay Hunt syndrome, flu-like infections, or an immune flare-up, TCM does not describe the virus in biomedical terms. Instead, it interprets the condition as an external pathogenic factor disrupting the body’s internal balance.
How Does TCM View Virus-Associated Bell’s Palsy?
1. Wind-Heat Toxin
Signs and symptoms: Cold or flu symptoms, sore throat, fever, swollen glands, ear pain, and facial inflammation.
Treatment principle: Expel Wind, clear Heat, resolve toxicity, and open the channels.
TCM interpretation: External Wind combined with Heat or Toxic Heat invades the channels, causing inflammation and obstructing the flow of Qi and Blood within the facial meridians.
2. Damp-Heat or Toxic Heat
Signs and symptoms: Heaviness, swelling, redness, ear vesicles (such as shingles), yellow phlegm, and digestive sluggishness.
Treatment principle: Clear Damp-Heat, detoxify, and transform Phlegm.
TCM interpretation: Dampness and Heat combine with toxin, obstructing circulation within the channels and collaterals.
3. Zheng-Qi Deficiency
Signs and symptoms: Stress, exhaustion, poor sleep, and overwork.
Treatment principle: Strengthen Wei-Qi (defensive Qi), support Spleen and Lung function, and prevent recurrence.
TCM interpretation: Wei-Qi becomes weakened, leaving the body more vulnerable to external pathogenic invasion.
4. Blood Deficiency with Channel Malnourishment
Signs and symptoms: Fatigue, pale complexion, dizziness, dry skin, numbness, muscle weakness, poor circulation, pale tongue, and thready pulse.
Treatment principle: Nourish Blood, regulate Qi and Blood circulation, and nourish the channels and sinews.
TCM interpretation:
When Blood is deficient, the channels and facial muscles become undernourished, weakening the body’s ability to support normal movement and tissue recovery. As a result, residual pathogenic factors may remain within the meridians, delaying healing and prolonging facial weakness or stiffness.
Once the patient’s condition has stabilised, acupuncture treatment (2, 3) should be considered as early as possible. The first seven days are especially crucial for recovery. Shallow needling is generally preferred, particularly on the affected side of the face. Daily treatment is considered ideal, although treatment three to four times per week may still be effective.
However, electroacupuncture is usually avoided during the first seven days, as the facial nerves are already inflamed and damaged, and excessive stimulation is not recommended during the acute stage.
I spoke with the little girl’s mother to better understand the onset of her condition. The child had suffered from a fever for three days in April, and on the fourth day, the left side of her face became paralysed. She was unable to blink her left eye, and the muscles around her mouth became difficult to control.
The recovery process may take approximately 20 days if daily treatment is provided, although outcomes vary depending on the patient’s condition and constitution. During my placement, I witnessed encouraging improvement by her sixth treatment on the fifteenth day. The facial muscles on the affected side had become more relaxed, especially around her left eye and mouth, which were beginning to move more naturally.
According to her mother, the only remaining noticeable issue was that her mouth would still deviate slightly when smiling or crying. She had initially started treatment twice a week from the end of April until mid-May.
On my last day of placement, I saw the little girl again. She was noticeably more cheerful, talkative, and relaxed than when I first met her at the Acupuncture Department.
Seven Key Lifestyle Suggestions for Patients
- Consume more vegetables and fibre-rich foods in your diet, including tofu, bean products, sweetcorn, lean meat, onions, seaweed, red dates, hawthorn (Shanzha), bitter melon, winter melon, bananas, aubergines, pumpkins, and blackberries.
- Avoid spicy and overly sour foods, hot-natured foods, strong tea, alcoholic drinks, lamb, and animal organs such as liver and kidneys.
- Soak your feet in warm water before bedtime for 10–20 minutes to promote circulation and relaxation.
- Minimise overstimulation from activities such as excessive phone use, television, and laptop screen time.
- Moderate exercise is beneficial for recovery. Listening to calming music, maintaining a regular sleeping pattern, and keeping emotions stable may also support healing.
- Perform gentle facial muscle exercises regularly, such as raising the eyebrows, tightly closing the eyes, puffing the cheeks, opening the mouth, wrinkling the nose, and smiling gently. Applying a warm damp towel to the neck and facial area may help relax the muscles. Avoid washing the face with icy cold water, as cold stimulation may aggravate the condition. During windy or cold weather, keep the face and neck well protected.
- When facial muscles feel weak or difficult to control, practise gently closing the eyes and mouth tightly to improve muscle coordination and awareness.
This placement experience deepened my understanding not only of Bell’s Palsy from both biomedical and TCM perspectives, but also of the importance of early intervention, patient reassurance, and consistent treatment. Most importantly, it reminded me that healing is not only about restoring physical movement, but also about rebuilding confidence, comfort, and hope in the patient’s daily life.
