Where can I buy real gravel products?

You can go to Tong Ren Tang to see, there are stones sold in Tong Ren Tang here in Beijing, and they have been sold for several years, and their reputation has been very good. If the local Tong Ren Tang is not sold, you can buy it online on Toucui, which is the same as what Tong Ren Tang sells, which are all "Si Binbao" brand stone products, ** may be discounted. Moreover, now the stone is mythologized by many merchants, and what can be worn on the body can "cure all diseases", which is an exaggeration.

Excerpt: The composition analysis of Sibin pumice stone by the Institute of Geology of the Chinese Academy of Sciences shows that the stone contains more than 30 kinds of rare earths and trace elements that are beneficial to the human body, such as strontium, titanium, chromium, manganese and zinc. The Institute of Acupuncture and Moxibustion of the China Academy of Traditional Chinese Medicine and the Beijing Sibin Stone Technology Development Center (Sibin Baotou Stone) carried out the detection of Sibin Stone acting on specific acupuncture points of the human body to observe the improvement of human microcirculation shows that

The stone can significantly accelerate the blood flow rate of the nail fold microcirculation, and its increase in value can reach more than 20% and the effect is sustained.

The stone is a traditional Chinese medicine physiotherapy utensil, which can usually be purchased in a Chinese medicine store, ** about 100 yuan. Although the stone sold in some places is cheap, it has basically not been tested and is not safe to use. Moreover, the stone products of regular merchants usually have medical device record numbers, ingredient test reports, far-infrared and ultrasonic test reports, etc.

The origin of the stone is generally Surabaya

Gravel generally refers to microcrystalline limestone. The rocks composed of microcrystalline calcite and < argillite calcite are called microcrystalline limestone and argillaceous (or cryptocrystalline) limestone, respectively, and are sometimes collectively referred to as limestone, which can also be called lithographed limestone (for lithographic printing).

These rocks are the product of very weak hydrodynamic or hydrostatic environments, and are formed under conditions similar to those of clay rocks. Microcrystalline limestone is a dense massive microcrystalline aggregate of limestone, the main chemical composition is calcium carbonate, which is a sedimentary rock.

Microcrystalline limestone is mostly used as traditional Chinese medicine physiotherapy equipment and health care products. Because its composition is calcite, the hardness is 3, and the toughness is low, so hard objects should be avoided and beaten. It is easy to react with acids.

**The origin of Sibin stone originates from the ancient Surabaya Basin, the ancient Surabaya Basin flows through many provinces, does not refer to the current Surabaya City, Beijing is not necessarily roast duck, and the Surabaya product is not necessarily the stone.

Now some businesses in order to make huge profits, regardless of the health of consumers, crazy tampering with and hyping the "stone origin concept", all kinds of stone quality is unknown, rough appearance, specifications are not.

1. The crazy birth of stones of various colors has led to the fallacy that the stones of "Surabaya" are called stones, and that stones can cure diseases.

Stone is a general term for stone medical devices in traditional Chinese medicine, and the Sibin stone made of Sibin pumice stone is the top grade of stone products. The origin of Sibin pumice stone originates from the ancient Surabaya Basin, which flows through many provinces, and does not necessarily refer to the current Surabaya City. It is worth noting that the origin alone can not distinguish the authenticity of the stone, because there are more stones produced in the same area, but the function and efficacy are very different.

To identify the stone, it is still necessary to rely on the composition and characteristics of the stone.

The origin of Sibin stone is the source of the Si River in Surabaya, Shandong. Surabaya is located in the south-central part of Shandong Province, at the southern foot of the Taiyi Mountains, between 35°28 -35°48 north latitude and 117°5 -117°35 east latitude. The county boundary is bordered by Pingyi in the east, Qufu in the west, Zou Cheng in the south, Xintai in the north, and Ningyang in the northwest.

The maximum horizontal distance of the county border is 46 kilometers from east to west, and the maximum longitudinal distance from north to south is 46 kilometers. The total area is square kilometers. Among them, low mountains and hills are square kilometers, and river valleys are flat square kilometers.

The county seat is located in the central part of the county, in the west of the county, in the lower reaches of the Ji River. 40 kilometers east to Pingyi County, 35 kilometers to the county boundary; 47 kilometers to Zoucheng City in the south and 20 kilometers to the county; 30 kilometers west to Qufu City and kilometers to the county boundary; It is 80 kilometers north to Xintai City and kilometers to the county border. Taisi Chi Jade Mountain is located at the junction of Surabaya and Xintai, a mountain is divided into two areas, and there are boundary monuments at more than 900 meters.

Stone is a general term for stone medical equipment, and stones that can cure diseases can be called stones. Since it is a general term, it can come in a variety of colors and come from different sources. What we usually call the origin of the stone refers to the origin of the Sibin stone.

Sibin stone is the top grade in the stone, its raw material is Sibin pumice, Sibin pumice stone origin from the ancient Surabaya Basin, the ancient Surabaya Basin flows through many provinces, does not refer to the current Surabaya City.

Hello, the authentic Sibin stone is produced in Surabaya, Shandong.

Strictly speaking: the best stone is from the ancient Surabaya Basin Shandong section, Surabaya County and the Surabaya Basin is different, just like the Yangtze River Basin is not a specific place. Nowadays, many businesses use the Surabaya Basin recorded in ancient books that consumers do not have a clear understanding, and the vague concept of the origin mistakenly refers to the Surabaya Basin as the current Surabaya County, but it is not.

The origin of the stone is the Surabaya Basin, because the ancient saying called the Surabaya Basin "Sibin", so it is called Sibin pumice. In ancient times, the Surabaya basin was larger than it is now, and the name of Surabaya County was derived from the Si River.

Sibin pumice, the true color of Xuanhuang", this is the description of the color of the raw material "Sibin pumice" in the ancient book, and the "Xuan" referred to here is interpreted as "black" (Xinhua Dictionary 542 pages). The skin of Sibin pumice rough stone is gray yellow, but it is black after polishing and polishing process, and it will become black and shiny after long-term absorption of human oil, which is a black stone.

Surabaya County is a county under the jurisdiction of Jining City, Shandong Province, located in the south-central part of Shandong Province, at the southern foot of the Taiyi Mountains. The topography of Surabaya County is high in the north and south, low in the middle, and slopes from east to west. The highest point in Surabaya County, Fengxian Mountain, is 608 meters above sea level, and belongs to the warm temperate monsoon climate zone.

The Sihe River originates from the foothills of Dongbeiwei Mountain, Quanlin Town, Sishui County, and is named after the four sources of Baotu, washing bowl, Xiangshui and Hongshi Spring. The current Sihe River flows through Surabaya County, Qufu, Yanzhou, Zoucheng border, and Jining, and flows into Weishan Lake.

Summary. Usually, the origin of the stone refers to the origin of the Sibin stone, which is located on the bank of the Sihe River in Sishui County, Jining City, Shandong Province. Stone is a general term that refers to a class of stones that can be used to heal diseases.

As a result, the stone can come in a variety of colors and come from different places. Among them, Sibin boulder is the top grade in the boulder, and its raw material is Sibin pumice, and Sibin pumice stone comes from the ancient Surabaya Basin, which flows through many provinces, and today's Surabaya County is not the same thing. The scientific name of Sibin boulder rock is "silty limestone", its color is yellow, the main component is microcrystalline limestone, and contains strontium, titanium, chromium, manganese, zinc and other more than 30 kinds of rare earths and trace elements that are beneficial to the human body.

Sibin boulder is an extremely valuable rock variety, and the reserves are very small. Regarding its causes, experts from the China National Bureau put forward the meteorite impact theory after the geological survey and research of the Sibin gravel production area: 65 million years ago, the meteor shower hit the southwest of Shandong (now the area of Surabaya County, Shandong Province), and the surface rock layer was produced after impacting, and in the high-temperature, high-pressure, plasma environment, the interstellar material and the surface rock layer blended, infiltrated and deposited each other, and finally formed the current Sibin stone.
