膏剂作用比较广泛,无论是内服还是外用,由于其具有一定的稠度,故而具有:有效成分含量高、析出速度缓慢、作用长期持久、局部疗效切实等优点。徐灵胎说:“今所用之膏药,古人谓之薄贴,其用大端有二:一以治表,一以治里。治表者,如呼脓祛腐,止痛生肌并遮风护肉之类,其膏宜轻薄日换。治里者,或驱风寒,或和气血,或消痰痞,或壮筋骨,其方甚灵,药亦随病加减,其膏宜重厚久贴。”
Plaster has a wide range of functions, whether for internal or external use, because of its certain consistency, it has the following advantages: high content of active ingredients, slow precipitation speed, long-term and lasting effect, and effective local effect. Xu Lingtai said: "the plaster used today is called thin paste by the ancients. There are two big ends: one is to treat the surface, the other is to treat the interior. For those who treat the surface, such as purulent purulent, putrid, pain relieving, muscle building, wind shielding and meat protecting, the ointment should be changed in a light and thin way every day. In the treatment of internal diseases, it can dispel the wind and cold, or mix with Qi and blood, or eliminate phlegm and ruffian, or strengthen the muscles and bones. The prescription is very flexible, and the medicine is also increased and decreased with the disease. The ointment should be thick and pasted for a long time. "
