Herbal Treatment for Trigeminal Neuralgia: Insights from the Compendium of Materia Medica
Introduction
Trigeminal neuralgia (TN), also known as tic douloureux, is a chronic pain condition that affects the trigeminal nerve, responsible for sensation in the face. The pain associated with TN is often described as sharp, shooting, or electric-like, severely impacting the quality of life. Modern treatments for TN include medications and surgeries, but Traditional Chinese Medicine (TCM) provides alternative natural remedies.
The Compendium of Materia Medica (本草纲目), an ancient Chinese text, offers valuable insights into the use of herbal medicine for managing trigeminal neuralgia. This article explores these treatments, including herbal formulas, their dosages, and specific points of acupuncture that help relieve nerve pain.
TCM Understanding of Trigeminal Neuralgia
In TCM, trigeminal neuralgia is understood as a disorder of Qi and Blood stagnation, often involving internal wind and fire rising to the face. The imbalance in the body leads to blocked meridians, which causes the sharp nerve pain experienced in TN.
The treatment strategy focuses on moving stagnant Qi and Blood, calming internal wind, clearing heat, and nourishing Yin to restore harmony to the body. Herbal remedies from the Compendium of Materia Medica are particularly effective for addressing these imbalances and providing lasting relief.
Key Herbal Remedies for Trigeminal Neuralgia in the Compendium of Materia Medica
1. Chuan Xiong (川芎) – Ligusticum Chuanxiong
Properties: Pungent, warm
Meridians Entered: Liver, gallbladder, pericardium
Function: Moves Qi and Blood, expels wind, alleviates pain
Chuan Xiong is a fundamental herb for treating neuralgia. It helps move stagnant Qi and Blood, which is believed to be the root cause of trigeminal neuralgia. Its ability to expel wind makes it particularly useful for addressing the facial pain characteristic of TN.
Dosage: 6-9 grams, decocted for oral consumption.
2. Bai Zhi (白芷) – Angelica Dahurica
Properties: Pungent, warm
Meridians Entered: Lung, stomach
Function: Expels wind, opens nasal passages, alleviates pain
Bai Zhi is commonly used in TCM for facial pain, particularly trigeminal neuralgia. Its warming properties help disperse wind and cold from the face, reducing pain intensity and improving circulation in the affected areas.
Dosage: 3-9 grams, taken as a decoction.
3. Dan Shen (丹参) – Salvia Miltiorrhiza
Properties: Bitter, slightly cold
Meridians Entered: Heart, liver
Function: Invigorates blood, dispels stasis, clears heat, soothes irritability
Dan Shen is known for its ability to move blood and dissolve stasis, which is critical for addressing the blocked meridians in trigeminal neuralgia. Its cooling effect helps clear heat, especially useful in cases where inflammation accompanies the nerve pain.
Dosage: 9-15 grams, decocted and consumed twice daily.

Acupuncture and Herbal Medicine Synergy
In addition to herbal treatments, TCM strongly emphasizes the role of acupuncture in managing trigeminal neuralgia. Acupuncture targets specific points along the meridians connected to the trigeminal nerve, helping to alleviate pain and restore Qi flow.
Key Acupuncture Points for Trigeminal Neuralgia:
- ST7 (Xiaguan): Located in front of the ear, this point is particularly effective for facial pain, especially along the jawline.
- LI4 (Hegu): Found between the thumb and index finger, this point is a powerful analgesic and helps regulate Qi throughout the body.
- GB20 (Fengchi): Situated at the base of the skull, this point helps dispel wind and relieve head and facial pain.
- LV3 (Taichong): A primary point for moving Liver Qi and reducing stagnation, important for treating trigeminal neuralgia’s root causes.
Lifestyle and Dietary Considerations for Trigeminal Neuralgia
In TCM, lifestyle and diet are critical components of managing chronic pain conditions like trigeminal neuralgia. Avoiding stress and following a balanced diet that nourishes the liver and promotes blood circulation can enhance the effects of herbal treatment.
Dietary Recommendations:
- Incorporate foods that invigorate blood and improve circulation, such as garlic, ginger, and turmeric.
- Avoid cold and raw foods that can exacerbate wind and cold stagnation in the body.
- Drink plenty of warm fluids to keep the body’s Qi flowing smoothly.
