Items de localisation
Deng 1993
Remarque: Il ne faut pas confondre la localisation de Fengchi 20VB avec celle de Yifeng 17TR, mentionnée dans Su Wen annoté par Wang. Les autres ouvrages localisent ce point sous l'occiput, à proximité de la ligne de plantation des cheveux, dans la dépression située à l'extérieur du grand muscle sur la nuque. Actuellement, on situe Fengchi 20VB sur la nuque, au-dessous de l'occiput, au niveau de Fengfu 16VG, et dans la dépression qui se forme entre les attaches supérieures du muscle sterno-cléido-mastoïdien et du muscle trapèze.

Needle oblique towards the tip of the nose 0.5-l.0 in. | Moxa stick 3 min.,3 moxa cones | Li Su Huai 1976 |
Selon Su wen, puncturer à 0,4 distance ; 0,3 distance, selon Jia yi jing. Selon Tong ren, puncturer à 0,7 distance, laisser l'aiguille le temps de 3 expirations, selon Jia yi jing, puncturer à 1,2 distance ; en cas d'atteinte par le grand vent, il faut d'abord tonifier puis disperser, laisser l'aiguille le temps de 5 expirations, disperser le temps de 7 inspirations | Selon Tong ren appliquer 3 cônes de moxa, selon Jia yi jing la moxibustion est moins efficace que la puncture ; appliquer de 7 à 100 cônes de moxa par jour | Zhen jiu ju ying (Guillaume 1995) |
Piqûre perpendiculaire, au même niveau que le lobe de l'oreille, légèrement vers le bas, à 1-1,5 distance Piquer obliquement vers le Fengchi du côté opposé, à 2-3 distances | Cautériser 3-7 fois, chauffer 5-10 minutes | Roustan 1979 |
Puncture entre 0,5 et 1 distance de profondeur, pointe de l'aiguille inclinée vers le bas en direction de la pointe du nez | Cautérisation avec 3 à 7 cônes de moxa, moxibustion pendant 5 à 7 minutes | Guillaume 1995 |

Acupuncture at Fengchi (GB20) in the posterior neck improves vertigo. However, subarachnoid hemorrhage and spinal epidural hematoma have been reported to occur after acupuncture in the posterior neck. Therefore, in the present study, we assessed the safety of acupuncture at Fengchi. Laboratory tests and adverse event reports were used to evaluate the safety of different acupuncture manipulations for the treatment of posterior circulation ischemia with vertigo. A total of 136 patients were randomly assigned to four groups. Verum acupuncture was conducted with different needle insertion directions (contralateral paropia or prominentia laryngea) and different needle twisting frequencies (60 or 120 times/minute) at Fengchi and matching acupoints (for example, Zhongwan [CV12], Qihai [CV6], Zusanli [ST36], and Fenglong [ST40]). The patients received 14 treatments over 3-4 weeks. Routine blood analysis, hepatic and renal function tests, urine and feces tests and electrocardiography were performed before the first treatment session and after the final session. Adverse events were recorded after every session. Of the 136 patients, 120 completed the study. There were no significant differences between pretreatment and posttreatment test results in any of the groups. Only five patients suffered from minor adverse events (needling pain, slight hematoma and transient chest tightness). No serious adverse events were found. Our results indicate that a 14-session course of needling at Fengchi is relatively safe for treating posterior circulation ischemia with vertigo.

Localisation et puncture du point. Si le 20VB gauche est puncturé l'aiguille doit être dirigée vers l'orbite droite, la puncture doit donc être croisée, à une profondeur de 1,2 à 1,5 cm. En cas de céphalées et vertiges liés à un traumatisme cranien ajouter 20VG et 16VG. Epilepsie : 14VG, 20BG et 5P. Céphalée unilatérale : 20VG et Tai Yang. Vertiges : 18V et 36E. Bourdonnement : 2VB et 17TR. Douleur abdominale : 36E et 11V.
Objective | Analysis of clinical efficacy of acupuncture Fengchi and Quchi acupoint in the treatment of primary hypertension. |

To observe the curative effect and the hemodynamic change of cervical vertigo treated by acupuncture, 66 patients were randomly divided into two groups: group A in which acupoints Yuzhen (BL 9) and Fengchi (GB 20) were used and Group B in which Cervical Jiaji points (C4.6) were used. Before and after treatment, the symptom of the cervical vertigo and the grade variety of function and the change of Color Doppler Flow Imaging (CDFI) of vertebral artery were observed. After treatment, the grade in two groups increased, there was a remarkable difference between two groups(P < 0.05); after treatment, the grade of vertigo degree increased, there was a remarkable difference between two groups(P < 0.05); needling Yuzhen (BL 9) and Fengchi (GB 20) can remarkably improve the symptom of cervical vertigo and vertebral artery blood flow rate, and the curative effect was superior to needling Jiaji points.
AIM: To study the nervous-pathways of Fengch'ih acupuncture by means of anterograde transport of aqueous solution of horseradish peroxidase (HRP). METHODS: Fifty Wistar rats were randomly divided into 1, 2, 3, 4, and 5 d groups, and every group had 10 animals. HRP (30% aqueous solution) was injected into a Fengch'ih. Serial, transverse or capital, 40 mum sections of the cervical spinal ganglia, cervical and thoracic spinal cord segment and brain were cut on a cryotome. Sections were incubated for HRP histochemistry according to the tetramethylbenzidine (TMB). Part of the sections were counterstained with neutral red. RESULTS: After 1 d of survival times, many labeled cell bodies were found in 1-4 cervical spinal ganglia, anterior horn of 1-4 cervical spinal cord, ventromedial division of facial nucleus, accessory facial nucleus ipsilaterally. With increasing survival times, the intensity of labeled cells were slightly decreased. CONCLUSION: Fengch'ih may bring into full play its effect by correlation of posterior ear branch of facial nerve and anterior branch of 2-3 cervical nerve with 1-4 cervical the anterior horn of the spinal cord, ventromedial division of facial nucleus, accessory facial nucleus
