[ China Pharmaceutical Network Health and Wellness ] Drugs have a shelf life, and Chinese herbal medicine is no exception. Li Hong, the Chinese pharmacist in charge of the Pharmacy Department of Tangshan Traditional Chinese Medicine Hospital, said: There is no relevant shelf life requirement for Chinese herbal medicines, but it does not mean that Chinese herbal medicines can be preserved indefinitely. Some people think that the better the Chinese herbal medicines are, the better they are, and even the blind collection. This is a misunderstanding.
Chinese herbal medicines are available for purchase
“Only through proper and reasonable preservation methods can Chinese herbal medicines be preserved.†Most common Chinese herbal medicines should be stored in a cool, ventilated and dry place. High-grade Chinese herbal medicines such as Cordyceps sinensis and ginseng can be stored in an environment of minus 5 degrees in the refrigerator. However, there are also some Chinese herbal medicines that are “more and better.†Chinese herbal medicines such as dried tangerine peel generally need to be stored for more than 5 years, and the efficacy is better. "Most of Chinese herbal medicines are best eaten early. Once the quality of the medicinal materials is reduced, the efficacy of the medicinal materials is reduced. Sometimes, not only does it not have health care and health effects, but it also affects the health of the body." How much is allocated.
Chinese herbal medicine is not as good as possible
At present, the more common view of the Chinese medicine industry is that Chinese herbal medicines can be truly "guaranteed" during the shelf life and using appropriate preservation methods. Once the quality of Chinese herbal medicines declines, the efficacy of the medicines is reduced, and the effect of healing and saving people cannot be achieved. Naturally, it cannot be “preserved and value-addedâ€, and the collection is worthless.
Herbal medicine. Once the herbs are made into pieces, the efficacy will decrease with time and the shelf life should not exceed 2 years. Take herbal medicines such as ginseng. The longer the medicine is in the ground, the better it will be. However, once it has been dug out and made into pieces, the efficacy will decrease with time. After storage for more than 1 year, the active ingredient will be lost by 20%~30%; the rhubarb will be stored for more than 5 years, and the ingredients with medicinal valueè’½The terpenoids will all fail. Angelica, medlar, etc. contain a lot of fatty oils and sticky sugar components. Although they are not easy to be infected by insects, they are easy to "go oil" for a long time, that is, oil-like substances will appear on the surface, and such Chinese medicines have no effect at all.
Woody drugs. Such as: hawthorn meat, cork, honeysuckle and so on. The shelf life of these woody drugs can be as long as 4 years. However, experts have found that some herbs have been stored for a long time, although there is no deterioration in appearance, but the efficacy is reduced. For example, peppermint, musk sage and other volatile ingredients, such as storage for a long time, the fragrance will seriously affect the quality of the drug, thereby reducing the efficacy.
Mineral medicine. A mineral-based medicinal material in traditional medicine. The molecular formulas of mineral medicines such as keel, magnetite and saltpeter are relatively stable, and it is not a problem to put it for a long time. However, long-term storage will still have an impact on the efficacy of the drug. In general, the storage time should not exceed 10 years.
Learn to discern whether Chinese herbal medicines have deteriorated
Most of the sugar-containing Chinese herbal medicines are mainly plant and animal. They mainly contain starch, protein, fat, sugar, cellulose, etc. These ingredients are the nutrients needed for the growth and reproduction of worms. Therefore, Chinese medicines that are powdery, fleshy, and sugary, and loose in texture are susceptible to insects such as yam, lotus seeds, angelica, bitter almonds, and Cistanche. Hard drugs such as Sanqi and Yujin are not susceptible to insects. After the Chinese medicinal materials are passed through the worms, some of them form pores to produce glutinous rice, and some are even completely pulverized. For example, after the honeysuckle and chrysanthemum worms are scattered, the whole petals are scattered; after the skin, flesh and internal organs of the soil mites are hollowed out, the residual part may be mildewed by the contamination of the worm body and its excrement, resulting in odor or discoloration.
More "oil" is afraid of getting wet. After the damp, discoloration, and deterioration of the medicinal material, the surface exhibits a change in the oily substance, which is called "oil". Herbs containing fatty oils, volatile oils or sugars, such as bitter almonds, angelica, and cinnamon, are prone to "oil". Check whether the medicine is "oily", you can start from the following points: smelling smell, nutmeg oil is easy to produce strong odor, mulberry has sugary smell; look color, mainly depends on the color, oil quality, brittleness of the medicine And the degree of adhesion. When the angelica, the solitary, etc., the oil will appear on the surface of the medicinal material, the wheat and winter will stick together when the oil is removed; if the texture is touched, if the medicinal material has a sticky feeling, it means that the oil has gone.
After processing, it is moldy. When processing medicinal materials, it is difficult to handle clean and easy to attach mold spores. Under the influence of appropriate temperature and humidity, spore germination hyphae can cause mildew of the drug. Common mold-prone Chinese medicine pieces include asparagus, melon, safflower, and earthworm. Under normal circumstances, the medicine should be sealed immediately after removal, so as to minimize the air flow around the medicine. It is found that there is mildew in the medicinal materials, and when the degree is light, the hyphae should be removed and used. You can use a soft brush or a rag to wipe the medicine with water. The medicinal material that can be wetted can also be washed directly with water. If it is inconvenient to brush, it can be mixed with rice to knock the hyphae.
Here, Li Hong reminds everyone that if the drug has serious mildew and oil, it should not be taken. Once the patient has mistreated the deteriorating Chinese medicine, vomiting, diarrhea, dizziness, etc.
Symptoms should be treated immediately to prevent poisoning.
