The invention discloses a Houttuynia cordata extract preparation and application thereof. Each liter of the preparation consists of the following raw materials: 0.1-25 g of Houttuynia cordata volatile extract, 0.5-50 g of isotonicity agent, 0.1-25 g of solubilizer, and 0.5 g of citric acid. ～5g, adjust the pH value to 4-7 with disodium hydrogen phosphate or sodium citrate, and the remaining amount of double distilled water; compared with the Houttuynia cordata injection, the Houttuynia cordata extract preparation of the present invention is regulated by an isotonic agent, which is irritating to the respiratory tract. and the Houttuynia cordata extract preparation prepared by the present invention is matched with an atomizer. After being adjusted by solvents such as cosolvents and isotonic agents, the surface tension of the liquid is smaller, the diameter of the formed droplets is small and uniform, and the bioavailability Higher degree of safety and less safety risk; the Houttuynia cordata extract is formulated with volatile oil, and the stability between batches is also better. |
