What are the common Chinese medicine preparations?

At present, the commonly used dosage forms are soup, pill, powder, ointment, Dan, wine and so on. As for which dosage form to adopt, it must be decided according to the medicinal properties and therapeutic needs.

In terms of medicinal properties, we should consider the toxicity, heat resistance and solubility of drugs. When toxic drugs are used as decoction, the effective components are most easily affected by water and heating, and the efficacy is difficult to master; Moreover, the decoction is absorbed quickly after oral administration and is easy to be poisoned. Therefore, when toxic drugs and drugs whose active ingredients are insoluble or insoluble in water or not resistant to high temperature are used, they should be used as pills, especially highly toxic drugs, and cannot be used as decoction or wine. In terms of absorption speed, powder is faster than pill, and decoction is faster than powder.

In the need of treatment, decoction should be used to clear the viscera, dredge the meridians and reach the limbs; Powder should be used to evacuate stagnation; Pills should be used to relieve symptoms and replenish qi slowly; Warm up the four veins and use wine appropriately; Nourishing should use ointment or pills. In addition, the powder can also be used as first aid, or for the application of sores and skin diseases and the external treatment of ointment. Pill powder, also known as Dan, is strong in nature and small in dosage. If pus is pulled out, pain is relieved and granulation is promoted, plaster can be used, budan medicine can be used, or both can be used.
