[ China Pharmaceutical Network Health Health ] Many people think that "the millennium ginseng, a hundred years old tangerine peel", the longer the Chinese medicine is placed, the better the drug effect. Many elderly people even store some Chinese medicines for collection, which is believed to enhance the efficacy of the medicines, but found that the medicines are mildewed or long-haired. The industry reminds that moldy long hair medicine should not be used, because mold enters the body will have an impact on the body, light diarrhea, but damage liver and kidney function, and even cause cancer.
Experts pointed out that in fact, Chinese medicine also has a certain shelf life. In the case of dried tangerine peel, although these herbs need to be stored for at least 3 years, they are effective, and the best period of efficacy is 3-10 years, but it is not stored as long as possible. The "hundred years old tangerine peel" that people have heard in their mouths can only be used as a collectible, and there is no drug effect.
Factors affecting the deterioration of traditional Chinese medicine
It is understood that there are many factors affecting the deterioration of traditional Chinese medicine, which requires people to need a suitable storage environment when storing Chinese herbal medicines. There are strict requirements on the temperature, humidity and air of the storage place, otherwise the Chinese medicine is prone to mold, rancidity and volatilization.
Storage time of Chinese medicine
The storage of traditional Chinese medicine is divided into decoctioned Chinese medicine and dried Chinese medicine. The former Chinese medicine decoction is generally packaged in a vacuum or in its own container. The higher the temperature, the faster the deterioration of the liquid.
According to the industry, when the room temperature reaches 25 ° C, the preservation period of the decoction can not exceed two days, if it is refrigerated, it will be stored for seven days. If the liquid contains protein, starch, and sugar, it will change faster. Therefore, in order to ensure the safety of the use of drugs, the sealed package of soup should be stored at zero to 5 ° C, and the storage time should not exceed seven days. If the liquid is odorous or has air bubbles, it cannot be taken.
For dry medicines that can be stored for a long time, the industry said that it can be generally divided into three categories: herbal medicines, woody medicines and mineral medicines. The shelf life of these three types of medicines varies. Among them, the shelf life of herbal medicines is generally about 2 years, such as ginseng, Cordyceps sinensis, etc., the drug effect will decrease with the passage of time, in order to improve the efficacy, some drugs even use fresh grass medicine. The shelf life of woody drugs can last up to 4 years, such as angelica and cockroaches. The ore-based medicines should not be stored for more than ten years, such as keel, magnetite, and saltpeter. In addition, the shelf life of volatile oils and lactones is generally one year.
It is worth noting that in the storage process, once the Chinese herbal medicine is found to have mildew and insects, it should be placed in a ventilated and dry place.
How to judge whether the medicine has efficacy or not
The medicinal materials will be affected by the environment, and there will be mildew, rot, biting by the insects, discoloration, odor, etc. How to judge whether the medicinal materials are effective or not, can they be used? Experts said that "look at it, smell one smell" can know the efficacy.
Look at the date of production. If there is no date of production, the medicinal materials can be visually observed for worms, mold, long hair, and decay. It is worth reminding that it is necessary to pay attention to whether some medicines containing a lot of fatty oil and sticky sugar ingredients are oily or rancid.
Second, smell the medicinal material. It can be judged whether the drug has the effect by smelling the medicinal material. If the medicinal material is odorous, the efficacy has been volatilized almost.
In addition, there must be some attention to the storage of medicinal materials. For example, herbal medicines are usually packed in burlap bags and placed in a dry and ventilated place. The wood medicine needs to be sealed in a plastic can, and the mineral medicine needs to be sealed in a cool place.
What is Indoor PTZ Camera
PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.
PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.Automatic tracking is divided into three types: one is through embedded video encoder, also known as intelligent visual server; the other is PC software; the other is to directly write the tracking algorithm to DSP chip, and then design the DSP chip as a hardware circuit on the high-speed ball motherboard, and the high-speed ball is directly read. Among the three types, the third type is used most in the current market.
The intelligent vision PTZ automatic tracking and monitoring system consists of an intelligent vision server (responsible for intelligent analysis and command) and a high-speed spherical camera (responsible for tracking targets). The automatic PTZ intelligent tracking function enables the camera to automatically PTZ drive its own PTZ and zoom lens, and automatically control the PTZ camera to rotate the PTZ in all directions and zoom the lens, and perform visual oriented automatic tracking for the locked moving target, so as to ensure that the tracking target continues to appear in the center of the lens with a close-up image, so that the security personnel can see the information more clearly, It can also be used for obtaining evidence afterwards. The automatic PTZ tracking module makes up for the narrow field of vision of fixed camera monitoring, which is an essential function of a perfect security monitoring system.
The intelligent vision PTZ automatic tracking and monitoring system has the target analysis function, and is equipped with a high-resolution camera, a large magnification optical zoom lens and a high speed PTZ, which can automatically capture suspicious targets quickly and accurately. By setting the preset position intelligent vision PTZ automatic tracking monitoring system, the preset position scanning, automatic cruise and other functions can be realized, and many special requirements of intelligent monitoring can also be realized. In addition, the intelligent vision PTZ automatic tracking and monitoring system also has the advantages of beautiful appearance and strong concealment, so it is very suitable for public security intelligent monitoring applications in airports, squares, rail transit, villas, government administrative units, military regions, museums and other types of places.
The automatic PTZ tracking and monitoring system integrates optics, electronics, machinery, information processing and network, and is composed of camera, power transmission, motion control device, image analysis, recognition, compression and communication based on high-speed parallel processing. It has the functions of video camera, position control, orientation and lens preset, moving object detection, recognition and tracking, flame and smoke detection and alarm, etc. It can be widely used in buildings, banks, airports, stations, customs, transportation, power, factories and mining enterprises and other security monitoring occasions.
