The basic situation of expiry date The concept of expiry date of drugs comes from the west, and all western medicines have expiry dates. Chinese patent medicines sold in medical institutions and pharmacies in China have a quasi-brand name of national medicine, and their validity period is mandatory; Traditional Chinese medicine and Chinese herbal pieces are not mandatory by the state.
How to ensure the quality of traditional Chinese medicine and Chinese herbal pieces?
To tell the truth, the product quality is really out of control. If it is a Chinese pharmacy in a hospital or a relatively large chain pharmacy, the safety can generally be guaranteed.
Validity period of Chinese patent medicine
This is actually a good thing for users. Otherwise, drugs will fail, toxic and harmful substances will increase, and everyone will not know that they are still in use. If there is a safety problem, it will be troublesome. Even with this requirement, there are still problems such as frequent adverse reactions of traditional Chinese medicine injections and other proprietary Chinese medicines, which are very necessary to be controlled. Therefore, it is necessary to give drugs a standard, a qualified standard, and draw the conclusion of validity period after long-term stability research, that is, to ensure that drugs are safe and effective within the validity period. For proprietary Chinese medicines, it is now mandatory and the expiration date must be indicated.
Validity period of traditional Chinese medicine
For traditional Chinese medicine, most of them are made by processing and drying. As long as it is stored properly, it will generally not deteriorate. Especially mineral drugs, are very stable and generally have no problem for ten years. However, the quality of some herbs may have declined, and the appearance has not changed, which does not mean that they are still effective. In particular, some medicinal materials containing volatile main components, if stored for too long, the effective components will volatilize, the quality will certainly not be guaranteed, and the curative effect will also decline. So, although there is no expiration date for this traditional Chinese medicine at present, I think it is estimated that there will be corresponding regulations soon. This is actually to avoid risks, and it is for the safety of people's medication.
Angong Niuhuang Pill can clear away heat and toxic materials, relieve shock and begin to understand. Used for fever, pathogen entering pericardium, febrile convulsion and delirium; Stroke coma, encephalitis, meningitis, toxic encephalopathy, cerebral hemorrhage and septicemia.
Why can Angong Niuhuang Pills be preserved for so long? Dr Yao believes that everything should be viewed from two sides, not across the board. For example, Angong Niuhuang Pill mentioned in Tong Ren Tang is honey pill, and its main components are mostly mineral Chinese medicine, which is not easy to deteriorate. It's covered with a thick layer of wax to isolate the air, basically? There is nothing to lose. Yes It is said that Tongrentang does have Angong Niuhuang Pills that have been preserved for more than 100 years, and they have not deteriorated. Tongrentang Chinese patent medicine Angong Niuhuang Pill was approved for only 48 months. This is actually a waste of resources.
Therefore, simply putting Angong Niuhuang Pills, if the wax layer is not broken, odorless and sticky, will basically not have adverse effects on the body. However, other proprietary Chinese medicines, mainly herbs and woody medicines, should still be used within the validity period.
How to preserve Angong Niuhuang Pills? Ventilation. In order to avoid the deterioration of Angong Niuhuang Pill, it should be placed in a cool and ventilated environment as far as possible, and Chinese herbal medicines in a closed environment are prone to mildew and deterioration.
Damp-proof angong Niuhuang pills should be stored in a dry and non-humid place, because the Chinese herbal medicines in them are easy to lose their medicinal properties and even deteriorate after being wetted.
Sun protection. Angong Niuhuang Pills must be kept away from direct sunlight and placed in a box or glass container with good shading and ventilation.
Prevent low temperature. Many people think that keeping drugs in the refrigerator can prolong the shelf life, but this is actually a wrong idea. Because it is easy to condense water in the refrigerator, the medicine will deteriorate due to moisture.
Pressure protection. Angong Niuhuang Pill should be placed on the top layer as far as possible to avoid being squeezed by heavy objects, which will damage the medicine and affect its normal preservation.
Don't destroy protective substances. Generally, Angong Niuhuang Pills have a protective layer sealed with wax on the surface, which can effectively protect the medicinal properties of drugs and extend the shelf life of drugs.
