What’s the Difference Between Fengchi and Baihui?
Fengchi and Baihui are often confused because they’re both located on the head and treat headaches. However, when you look closely, their mechanisms of action and target conditions are distinctly different. Fengchi is an exterior-releasing acupoint that expels “wind,” while Baihui is a qi-tonifying acupoint that elevates “central qi”—they have opposite characteristics. The effects differ dramatically depending on the symptoms.
Understanding Fengchi (GB20) in Depth
Precise Location
Fengchi is an important acupoint on the Gallbladder meridian, located in the hollow below the occipital bone. More precisely, starting from the back of the neck and feeling downward behind the ear to find the two mastoid processes, it’s located at the point where the neck muscles meet—in the depression between the trapezius and sternocleidomastoid muscles. Find the spot about a thumb’s width apart on each side. Tilting your head slightly forward makes it easier to locate the point.

True to its name “Wind,” Fengchi is effective when wind (external pathogenic factors) invade the body. It’s typical for the early stages of colds accompanied by chills and headaches, or excessive sneezing from allergies. It’s particularly effective when the neck is stiff and the shoulders feel tight, for headaches from eye strain, and for one-sided headaches from trigeminal neuralgia. The more acute the symptoms, the faster Fengchi works.
Pressure Technique and Tips
Since Fengchi is a superficial acupoint, careful pressure is needed. Place your thumbs on the acupoint and press upward (toward the brain) at about 15-30 degrees, applying pressure until you feel soreness and distension. Perform for 1-2 minutes per session, 2-3 times daily. During early cold symptoms, apply stronger stimulation; for chronic symptoms, frequent light stimulation is more effective. Drinking warm water within 30 minutes after pressure helps promote sweating.
Understanding Baihui (GV20) in Depth
Precise Location
Baihui is an acupoint on the Governing Vessel, located at the center of the vertex (crown of the head). The most accurate way to find it is at the intersection of the line connecting the apexes of both ears (extended upward over the head) and the midline running vertically up from the center of the face. You can find it by running your fingers upward over the head to locate the highest point of the vertex. Externally, it’s at the center of the line dividing the front and back hair in a 1:1 ratio.

Baihui is called “one character governing a hundred ailments” because of its wide-ranging effects. It’s particularly effective for chronic fatigue, lethargy, and lack of energy. It excels for daytime sleepiness despite sufficient nighttime sleep, mental fog, and poor concentration. It helps improve depression or anxiety when mood is depressed, and weakness from menopause. It also helps with chronic headaches, especially dull pain around the vertex or facial flushing.
Pressure Technique and Tips
Baihui requires deep stimulation. Gather 3-4 fingers on both hands and place them on the vertex, pressing downward (toward the brain center) with a tapping sensation. Apply pressure carefully—excessive force may cause dizziness. 2-3 minutes per session, 1-2 times daily is appropriate. Since Baihui has an upward tonifying effect, it’s better to perform it in the morning rather than evening to avoid disturbing sleep. For chronic fatigue, consistent daily stimulation is important.
Key Comparison Summary
| Item | Fengchi | Baihui |
|---|---|---|
| Corresponding Meridian | Gallbladder (GB) | Governing Vessel (GV) |
| Location | Between trapezius at back of neck | Center of vertex |
| Primary Effects | Colds, acute headaches, stiffness | Fatigue, lethargy, chronic headaches |
| Mode of Action | Superficial exterior-releasing (expel pathogenic wind) | Deep qi-tonifying (elevate central qi) |
| Location Difficulty | Moderate (neck flexion area) | Easy (center of vertex) |
| Pressure Intensity | Moderate pressure | Light pressure |
| Recommended Timing | When acute symptoms develop | Daily habitual maintenance |
Synergistic Effects When Pressed Together
Interestingly, Fengchi and Baihui are mutually complementary. When recovering from a cold, combining them—first using Fengchi to expel residual pathogenic wind, then using Baihui to restore original qi—is effective. When headaches and fatigue appear together during seasonal transitions, it’s good to first stimulate Fengchi to relieve symptoms (after 5 minutes) then stimulate Baihui. If chronic fatigue has weakened immunity, it’s better to first supplement qi and strength with Baihui, then use Fengchi if needed. When stimulating both in one day, pressing Baihui in the morning and Fengchi in the afternoon at different times doesn’t disrupt body rhythm.
Conclusion: Situation-Based Selection Guide
Choose Fengchi: I suddenly developed a headache starting yesterday | I have signs of a cold | My neck and shoulders are stiff | My eyes are fatigued | I was exposed to cold wind yesterday | I have sneezing and nasal discharge
Choose Baihui: I continue to feel fatigued | I feel foggy all day | Despite sleeping at night, I’m sleepy during the day | My mood is depressed | I have chronic headaches | My concentration has declined
Try Both: I have headache and fatigue together during seasonal transitions | I’m recovering from a cold | I have systemic symptoms from stress | I have fatigue and symptoms accumulated over a long period
