If you drink expired and deteriorated medicinal liquor, you will have symptoms such as nausea and vomiting, and even poisoning is life-threatening.

China people's research and application of wine can be described as a complete success. Since the appearance of wine, the contents of this cup have been interpreted into countless wonderful stories by our ancestors. So there was the feat of crouching tiger drunk, the heroic spirit of beating the mountain gate drunk by Lu, and the eternal joke of granny Liu lying drunk in Yihongyuan. ...
From brewing and drinking to tasting and discussing wine, wine has penetrated into all aspects of human beings and gradually formed its own unique culture-wine culture. Wine and medicine are inextricably linked. The traditional word "medicine" comes from "unitary", which is also wine.
This is probably because the ancestors accidentally ate fermented melon juice and found that it can treat some diseases such as deficiency cold and abdominal pain, thus making wine closely related to the initial medical activities. There is a treatise on decoction and medicine in Huangdi Neijing, which specifically discusses the way of medication.
The so-called "soup" is today's decoction, and "mash" is medicinal liquor. Obviously, during the Warring States period, people had a deep understanding of the medical function of medicinal liquor.
Modern medicinal liquor mostly uses 50-60% white wine. The basis is that because the alcohol concentration is too low, it is not conducive to the dissolution of effective components in Chinese herbal medicines, while the alcohol concentration is too high, sometimes it will absorb a small amount of water in Chinese herbal medicines, making the medicinal materials hard and the effective components difficult to dissolve.
Low-alcohol liquor, yellow wine, rice wine or fruit wine can also be used for people who are not good at drinking or who can't drink because of illness, but the extraction time should be appropriately extended or the reflux times should be appropriately increased to ensure the effective components in the medicine.
When making medicinal liquor, Chinese herbal medicines are usually soaked in wine. After a period of time, the effective components in Chinese herbal medicines are dissolved in the wine, which can be filtered to remove residues and then drunk.
