How to distinguish whether the brewed medicinal wine has deteriorated

Some people say that after so many years, this medicinal wine will undergo a chemical reaction and produce toxic substances, and it can no longer be drunk. So is this wine still drinkable?

Medicinal liquor refers to a clear liquid dosage form made by extracting the ingredients by soaking the distilled liquor of Chinese herbal medicines for internal or external use. Generally, the roots, stems, leaves, flowers, fruits, animal bodies, internal organs and some minerals of specific plants are soaked in a certain concentration of rice wine, liquor or wine in a certain proportion to dissolve the active ingredients of the drug and remove the slag after a certain period of time. As one of the commonly used dosage forms of traditional Chinese medicine, medicinal wine can play a good role in strengthening the body, preventing and treating diseases.

Many people believe that medicinal wine should be soaked for several months to more than a year, but in fact, the longer the soaking time, the better, so how long is it better to soak it? It depends on the temperature of soaking, the type of wine used, the concentration, the type of herbs soaked, the container of soaking, and the storage conditions. Generally, three months to one or two years is better.

There are many factors that influence the chemical composition of medicinal liquor:

At the same time, the wine is accompanied by the infiltration of the drug and the dissolution, displacement, diffusion and dissolution of chemical components. The length of the wine production time, the amount of wine used, the level of brewing temperature, and the length of storage time will affect the changes in the chemical composition of the medicine. The concentration, alcohol content, maceration temperature, and time of the sake used vary depending on the variety.

It is said that the time of soaking in medicinal wine is about 15 to 30 days, and the color is no longer deepened, indicating that most of the components of the drug have been dissolved. However, some herbs have a dense structure, and in order to fully dissolve the active ingredients, the time can be slightly longer. If the temperature is high, the soaking time is shorter, and when the temperature is low, the soaking time is longer.

Soaking medicinal wine does not produce harmful substances under normal circumstances. As for whether there will be a reaction to produce harmful substances and whether you can take it, it depends on the specific storage situation, and if the properties of the liquor do not change, it will not produce harmful substances, so you can take it with confidence.

1. How to identify whether the medicinal wine has deteriorated?

It can be judged by its color and fragrance. color, that is, to observe whether the color of the medicinal wine has changed, and it cannot be seriously blackened or turbid. Fragrance is to smell the aroma of medicinal wine and whether it maintains a mellow aroma. Taste, that is, the taste of medicinal wine can not have rancid taste.

The color of the liquid is uniform. Not some health care wine with high mineral content, after deterioration, the wine will be stratified, the bottom of the bottle will be precipitated, and the upper liquid will be clarified, in this case, the medicinal wine can no longer be drunk. The dealer will say that this is a precipitation for a long time, this excuse is not credible, and it is possible that the medicinal wine has precipitation, but there will be no such clarification and stratification.

Many health wines are packed in transparent containers, so that you can observe the inside. If the inner container wall is moldy, or if there is a mold layer on the surface of the medicinal liquor, then the medicinal liquor has deteriorated and can no longer be drunk.

Shelf life. Inside, the herbs soaked in the wine will not dissolve. If the medicinal materials in the health wine are rotten and soft, then the health wine will be spoiled, so don't drink it again.

If there is a big change in the taste of the same (one bottle) health wine before and after, it also proves that the medicinal wine has deteriorated. Some sellers will say that this is a normal phenomenon, saying that the taste of medicinal wine will change when it matures, and coax consumers. If you think about it carefully, you will know that the distributor is talking nonsense, if the medicinal wine is not mature, why did it come out for sale, isn't that also deceiving consumers?

Under the condition that the medicinal wine does not deteriorate, the color is relatively stable and will not change too much. If the current color of the medicinal wine is very different from when it was first purchased, it has deteriorated.

Some medicinal liquors are made in plastic bottles.

If the brewed wine is excluded from the influence of factors such as temperature, the bottle will be significantly inflated, and the medicinal wine will also deteriorate.

Medicinal wine generally deteriorates in three to five years, and there is no saying that it will become more and more fragrant. Expired medicinal liquor is not absorbed in the human body, the metabolism is not complete, and a part of it remains in the human body, drinking expired medicinal liquor can easily cause heart disease, and the body's body function is damaged.

If there is no mildew on the surface of the drug, it can be taken. Wine also has an antiseptic effect, and the medicinal wine made after the combination of wine and traditional Chinese medicine can not only maximize the role of traditional Chinese medicine, but also have good stability. Scientific studies have shown that when the ethanol content is more than 18%, it can delay the hydrolysis and deterioration of a variety of drugs and enhance the stability of the agent.

The higher the ethanol content, the higher the preservative of the agent. Therefore, medicinal wine is relatively easy to store for a long time, and is suitable for long-term consumption by the elderly, frail and chronically ill patients. As long as the pure Chinese medicine self-medicated wine does not deteriorate, it can be stored for a long time.
