Eucalyptus Pineapple Enteric Softgels are not antibiotics, but belong to the class of phlegmolytic drugs. Its main active ingredients are eucalyptus oleoresin, limonene and α-pinene. Its mechanism of action is similar to that of myrtle oil, i.e. it acts as an expectorant by promoting the dissolution of mucus, regulating the secretory activity of bronchial glands and accelerating the oscillation of bronchial epithelial cilia to facilitate the expulsion of phlegm. It is often used to treat cough and sputum symptoms caused by acute and chronic bronchitis and infectious inflammation of the lungs, especially in those with thick sputum. It can also be applied to acute and chronic sinusitis to make thick nasal mucus thinner and easier to expel. Antibiotics are a class of drugs that inhibit or kill pathogenic microorganisms, and expectorants are two different things, so Eucalyptus Lemongrass Enteric Softgels are not antibiotics.
