The meaning and characteristics of medicinal liquor and tincture

Medicinal liquor refers to a clear liquid dosage form made by extracting ingredients from medicinal materials with distilled liquor. Medicinal liquor is mostly taken orally and can be flavored and colored with sugar or honey. Medicinal liquor is a traditional dosage form with a long history. The "mash" in Huangdi Neijing refers to medicinal liquor for treating diseases. The taste of wine is sweet and pungent, which can promote blood circulation and remove blood stasis, promote drug efficacy and dispel cold. It contains a small amount of esters, acids, aldehydes and other ingredients, and its smell is mellow and unique. It is a good extraction solvent. Many components in medicinal materials are easily soluble in wine, so it is better to make some prescriptions for treating wind-cold-dampness arthralgia, warming kidney and supporting yang, expelling wind and promoting blood circulation, removing blood stasis and relieving pain into wine. However, children, pregnant women, patients with heart disease and hypertension should not take it.

Medicinal liquor can be prepared by extraction methods such as soaking, percolation or reflux. The concentration and dosage of distilled liquor used, soaking temperature and time, or percolation speed, and the alcohol content of finished products vary from variety to variety, and there is no uniform regulation at present.

Medicinal liquor should be sealed and stored in a cool place. During storage, a small amount of sediment that is slightly shaken and easily dispersed is allowed.

colour and lustre

It refers to the clear liquid dosage form made by extracting or dissolving drugs with ethanol with specified concentration, collecting and sorting, or diluting fluid extract. Most tinctures are taken orally, and a few are used externally. Tincture is flavored and colored without sugar or honey. Because ethanol has certain selectivity to the solubility of various components in medicinal materials, the liquid medicine leached by ethanol with appropriate concentration has less impurities, higher content of effective components, smaller dosage, convenient administration and less mildew. However, ethanol also has certain pharmacological effects, so the application of tincture is also limited.

Tincture can be prepared by soaking, percolation, reflux and other leaching methods, or by dissolution and dilution. Unless otherwise specified, if there is no method to determine the content of active ingredients, it is generally stipulated that each lml of tincture containing toxic medicinal materials is equivalent to 0.1g; Original medicinal materials; Other medicinal tinctures are equivalent to 0.2g 1 ml.

Tincture should be sealed in a light-proof container and stored in a cool place. When precipitation occurs after long-term storage, it can be removed by filtration when the contents of ethanol and effective components meet the relevant quality standards of various drugs.
