Description

Magnetic therapy underwear
Technical Field
The invention relates to a magnetic therapy underwear.
Background
The magnetic therapy is also called magnetic point therapy or magnetic field therapy. As the name suggests, magnetic therapy is to use a magnetic field with a certain intensity to act on certain parts of a human body to treat diseases. As early as more than 2000 years ago, ancient workers in China used magnetism to treat diseases. In the spring and autumn warring state, ancient famous medical magpie of China has been tried for magnet therapy; the characteristics of magnetite are recorded in the book of Shen nong Ben Cao Jing in the early stage of West Han dynasty: can be used for treating pain, arthralgia due to pungent and cold taste of Magnetitum, rheumatism, and arthralgia. There are many other descriptions that follow, and magnetite is used as a part of decoction or patent medicine. Until Ming Dynasty Li Shizhen, Magnetitum powder and various ointments are mixed to make into topical medicine. The proved recipe for treating nerve deafness and tinnitus by using magnetite is recommended by people in Qing Dynasty. In addition, there is a record in the medical book "ge zhi jing yuan": the people who benefit sleep, like the magnet, are used as the basin pillow, and the pillow is used for keeping the people away from dizziness and keeping the people constant, so that the health care effect is achieved.
Tianchi acupoint:
tianchi acupoint is located in the fourth intercostal space of the chest, 1 cun lateral to the nipple. On the other hand, "two cun behind the breast" in the same body and cun as the latter "(Wang Bing from Huang Di Nei Jing Su Wen & Qi Fu Lun); "one inch after breast, the fifth part below it" is an integration of acupuncture and moxibustion.
Tianchi acupoint significance: the high-temperature water vapor transported outside the pericardium is condensed into water passing through the ground and is transported downwards along the channels. Characteristics of qi and blood: the qi and blood substance is high-temperature water vapor in the upper part of the body. The operation rule is as follows: the heat-dissipating cold descending from the ground circulates downward through the pericardium. Specificity: the point of intersection between hand jueyin and foot shaoyang. The efficacy and the effect are as follows: the Tianchi point has the functions of regulating qi, relieving chest stuffiness, clearing heat, dissipating stagnation, promoting blood circulation, removing blood stasis, relieving chest stuffiness and regulating qi.
Tianchi acupoint is very important for modern women, especially for women living in large cities. Tianchi acupoint is the first acupoint of the pericardium channel, one inch above the nipple, and between the fifth rib, which is also the high-lying region of breast cancer, and deep qi and blood obstruction is one of the causes of cancer, and Tianchi acupoint is often massaged to dredge local qi and blood, so that self-kneading and massaging the Tianchi acupoint can prevent breast cancer.
The pressure of life of the women in the large city is large and many, the women are more likely to suffer from breast cancer, the incidence of the breast cancer is generally in great relation with the damage of bad emotion to go deep into the heart, the Tianchi point is a happy point of the women, the heart and the chest of the women can be widened by frequently rubbing the point, the qi is not easy to generate, the people can live long without generating the qi, and the breast cancer can be prevented because the bad emotion can be relieved by frequently rubbing the point. It is better to perform an-rou on this acupoint in combination with an-rou on Taichong acupoint, Jianjing acupoint and Qimen acupoint.
Tianchi point is mainly used for treating vexation, fullness in chest, hypochondriac pain, scrofula, swelling and pain in armpit, etc.; circulatory diseases: angina pectoris, epicardial inflammation; gynecological system diseases: mastitis, insufficient milk secretion; diseases of the surgical system: lymphoid tuberculosis, axillary lymphadenitis; and (3) the other: intercostal neuralgia, cerebral congestion, etc.
The edible sinus acupoint:
the food sinus is subordinate to the spleen meridian of foot taiyin. In the 5 th intercostal space, the anterior serratus muscle, there are intercostal medial and lateral muscles in the deep layer; there are thoracic lateral artery and vein; thoracic abdominal wall artery and vein; the 5 th intercostal nerve lateral cutaneous branch is distributed. It is commonly used to treat stomach qi failing to descend.
And (4) feeding the antrum. Food and stomach are affected by five cereals, spleen and earth. The sinuses, orifices and uterus. The point name means that water flows through the spleen meridian and falls into the spleen in the triple energizer. The substance in this acupoint is the water of the local meridians from the abdominal sorrow, and there are more spleen-earth substances which flow with the water of the local meridians, but the gaps in the local acupoints are connected with the spleen, and the spleen-earth substances return to the spleen with the flowing water of the local meridians, so the name is.
The function and the effect are as follows: the spleen is returned to spleen via qi and blood on body surface.
The main treatment is as follows: 1. distending pain in the chest and hypochondrium; 2. syndrome of stomach-qi failing to descend, such as belching, regurgitation, abdominal distention, etc.; 3. edema.
Breast root acupoints:
the Rugen acupoint is most likely to be various gynecological diseases for female friends in modern life, and is common for many female friends, and the Rugen acupoint can help women to solve gynecological diseases, so that the condition of the Rugen acupoint is
The breast root part, as the name implies, is the position of the heart below the breast and to the left of the breast root acupoint, and after hitting the heart, the breast root part can impact the heart and even cause shock.
Firstly, the points, namely the breast root points, are found right below the chest, the breast root points can be found along the lower part of the front surface of the breast by the thumbs of the two hands, then the breast root points on the two sides are pressed, but the force is not too strong, the deep breathing can be realized by matching the pressing frequency, the best pressing is realized before the sleep every night, the pressing frequency is about 20 times, and the excessive pressing is not suitable.
Since the breast root points have a plurality of advantages and can be used for health care through massaging the breast root points, the breast root points are frequently massaged, which is known by a plurality of people, and the breast root points are really beneficial, the breast can be enlarged firstly, the regrowth and the development of the breast can be stimulated through pressing the breast root points, and the long-term massage has obvious effect. Secondly, the breast distending pain can be relieved, the breast distending pain condition of women in the lactation period is often caused, the breast distending pain can be relieved by massaging the breast root acupuncture points, the breast hypogalactia condition in the lactation period can be treated, and the mastitis disease caused by the leucocytosis in the mammary gland can be relieved. Can also be used for treating respiratory diseases, and can be used for treating cough, asthma, chronic bronchitis and the like caused by obstructed respiratory tract due to the specificity of the part and great association with the respiratory organs.
